Electrical Shorting Problem - Help Needed. PLEASE!

Graham and ALL,
 
That's ok at home with the van garaged or just a day trip but when one goes camping for days/weeks on end, that breaker switch is back on for the duration, in which case the van needs to be fully functioning and independent with adequate recharging equipment while away from 240vac., i.e., you need solar (if the sun is shining and park in the sun) or huge camping battery with smart charging setup on the alternator circuit (park in the shade but don't stay in one place for too long).
 
I think anyone with a reasonably equipped campervan knows only too well that on an extended trip away from 240vac, then many of us have to conserve every scrap of electrical energy we can, especially if not driving every day. I don't have room for an even bigger camping battery. There is no room for a generator. No way would I tow a trailer for extra gear. In my case I try to limit electrical usage so as to make what I have available to the biggest consumer ... the 12vdc fridge. I'm not about to replace my fridge. The 70w solar panel helps a bit, I should go to say 200w. This means of a night time, I'll even use a head-torch for lighting or use the cabin lights running off the starter battery instead. To help avoid draining the starter battery, I just installed instead an AGM starting battery (coming to all of you soon in modern cars, especially European) so this one has a higher cranking and reserve capacity and faster and deeper charge capability (using the right equipment) and is fully sealed, no maintenance, no leakage, ideal for in-cabin confined space. Also it is compatible then with my AGM deep cycle camping battery so my smart charger automatically charges bulk/absorption/float stages to both at the same time for optimum condition/longevity.
 
Now all that is ok, would be even better if I throw enough cash at it, but meanwhile my experience shows that my van is experiencing flattening batteries just parked at home, then no wonder I'm having trouble supplying enough energy for the camper equipment after a few days camping, the circuit short is eating up my batteries.
 
If need be, I also can isolate my starting battery. But fixing the electrical short problem is definitely my first choice.
 
That is going to be the interesting bit. I feel a field day coming on. You fellas can come find the leak ok ... haha
 
Cheers.
Ken

I also hadyour problem.
After years of using my Syncro for work everyday with no problem,I then retired and my Syncro / battery decided to do likewise.
Being a practical person but not over technical I spent several days chasing the elusive before going to an auto electrician in despair.
He said he wasn't interested and would only do what I did and charge me a fortune.
 
Answer...Fit one new battery (optional) and a kill switch (the big red ones in which you can isolate the battery completely and then remove the key). I fitted mine near drivers lower left seat belt mount next to the battery.
 
Result....Syncro always starts.
             Insurance cost is lower
             The dash clock is right at least twice a day.
              If you ever roll or have an accident you can kill power immediately. (Ex rally experience).
 
Good luck Graham

Andy,
 
As Jim Davis (worldwide Syncro forum) pointed out, the fuse for the powerlocks are an add-on module on top of the main fuse block. At least that is how it's installed on the LHD.
 
Yours truly has gained some notoriety in his part of the world for driving his Syncros often enough. Some get driven maybe twice a year. Rarely do the vehicle drain their battery in less than 5-6 months of just sitting. Even then, there is still enough to spin the starter once or twice.
 
Compare that to newer vehicles. My brother's Ferrari sucks it's battery completely flat after about 14 days. On-all-the-time GPS locating system makes quick work of destroying the US$755 battery unless you use a tender. As Phill has pointed, there is little if any draw on components on T3's besides possibly the factory radio and clock.
 
I don't know if this helps as I did not perform the conversion myself. My 2wd T3 with a 2.2 EJT Subaru engine conversion does drain it's battery if not driven or started every 6-8 weeks. It might be coincidental as the previous owner also installed a host of other aftermarket parts. It might be worth throwing the question to the Subaru conversion in Yahoogroups if you are unable to track down the parasitic battery drain.

Purse strings were to tight for those fancy models.I got the multi xs 3600. Which is great for working at home as I usually have time on my side. Not like when I was working with BMW, We had 40amp smart chargers which we would leave connected during testing and programming. Sometimes programming would last nine hours with all sorts of drains being activated by the ecu including high amp units like headlights and active suspension. When I am not using the ctek in the workshop I keep it connected into my motorbike (that just sits there) as a tender.

Sorry Phill I didn't directly pay for it so can't give you a price but I regularly see them in the repco catalogue. I think - and don't quote me - they start at around $140 for a unit with no adjustments mine has three settings probably around $200 from there no idea. Greg

I found the 3600 on a local eBay website this afternoon for $111.  Good value.  There is plenty of technical detail available on this until and the others in the range.

Hi Ben,

 

I remember organising a presentation by the local CTEK people for the Volkswagen Club of Victoria last year, and one of their claims was that they were OEM suppliers to many major manufacturers, including Ferrari. Of course, Ferrari might want a ‘slight’ mark up on the price for attaching their badge.

Thanks, Les. I'm afraid to admit my brother has more money than sense. Especially car sense. He insist on using Ferrari branded parts only which translates to lots of Euros for everything including his battery tender.

 

Almost all the new VW's being sent on out part of the world come with a solar powered battery tender. VW dealers are supposed to give them away to customers upon demand. Some enterprising individuals have made a career of collecting them and reselling in places such as Ebay. They are an inexpensive or maybe free alternative to keep your battery charged. Of course, I am not suggesting that Andy use a the tender to hide his discharging problem.

Hi Phill,

They have various models available, but if I remember the most
popular/useful for basic automotive use was the 3500 (I think) which retails
about $160, but I've seen them at shows and on EBay around $125.

Brian,

Let's face it, even VW will add a dramatic mark-up. The difference between them and the people at the prancing horse stable besides the percentage is they alter specifications ever so slightly so the part is considered "special". Those special details supposedly justifies the 500+% mark-up. That was not a typo.

My apologies to Andy for getting this thread sidetracked.

And Italian electrical components supplier is an endorsment?

Brian,

I was at that presentation.  The prices quoted were high, as they usually are on introduction, but I have found the 3600 on an Australian eBay site for $111.

Ken,

I don’t actually need a charger – I have a flock of tem, including the original Arlec that was fitted by Trakka.  The charger that I use for most things is a Projecta smart charger, which charges in stages according to what the battery needs and eventually gets down to a monitored float charge.  The CTEK does the same thing.  My Projecta has gone a bit wobbly so I might have to get a CTEK to take its place.

What is not generally known is that the average battery charger will never produce better than about three quarters capacity in the very best of circumstances.  The smart chargers overcome this by mapping input volts and amps in such a way that nearly full charge can be achieved.  The better ones are also capable of resurrecting nominally dead batteries.  From memory, Hartmut quoted the case of his son allowing a battery to die through neglect but he was able to bring it back to life with a smart charger.

Les,
haha .... I see. So in short, you DO need a charger! :-)
 
This CTEK charger is max 3.6 amp output. Even the old tech Arlec charger Trakka installed was small at 12 amp. Crappy I know.
 
My scenario is this for a 20yo Trakka, not atypical. You've camped OR driven short distances between camps for three or four days, no ac access. The camping battery say 100 amps (too small I know but space is a premium) is getting lower and lower in charge as the 90amp alternator is struggling to supply the motor, keep both the starter and camping battery charged to say typical 70 - 80% AND run onboard services at the same time and it's hot (12vdc 115 litre fridge is running flat out) and its cloudy so the solar panel is struggling as well. So the fridge is borderline, she who must be obeyed is nagging because the fridge is too warm and you know that below a predetermined low voltage, the fridge compressor motor will sooner than later refuse to run. What to do? Well the only option is to bite the bullet and head for a van park with a powered site for one night to try and restore the battery/s and chill down the fridge. You have only say 12 hours ac access to do that. For a 3.6 amp charger, you haven't got a hope in haideys.
 
So in my case, to try and chill down a warm and fully stocked 12vdc 115 liter fridge overnight plus drive away with fully charged batteries (70 - 80% max) I need some serious grunt in my battery charger. Mine is 30, read 30 amps smart charger dual outputs plus I added an auto sensor module to the fridge so when it senses ac present, the fridge receives direct 12vdc power via ac leaving the battery charger to concentrate on running all other services overnight and recharge the lagging battery/s.
 
Sure we can talk about more efficient fridges and smart charging the alternator circuit and doubling the solar capacity etc etc., but these aren't typical for most 20 yo T3 campervans and add huge costs. It's a balancing act of cost and benefit.
 
For mine, this CTEK 3600 would be fine for slow or trickle charging, most suitable while the van is garaged at home.
Go consult Phills best buddy Collyn Rivers (sorry Phill haha) in his book "MotorHome Electrics & Caravans Too", he sets out all this sort of stuff plainly enough.
Cheers.

Australia's #1 job site If it exists, you'll find it on SEEK.

Ken,

There is a point where the available on-board battery capacity is inadequate for the draw and that’s where you are. 

Having a charger that is capable of delivering 30A will not give you a quicker charge because there is a limit to how quickly a battery will accept a charge before it is irreversibly damaged.  If your smart charger has a comprehensive function display, you will see that the voltage and the amperage constantly vary with the requirements of the charge cycle.  On my unit, I never see more than a few amps during the cycle.

That said,  I have read that some of the higher end smart chargers have astonishing initial recovery rates and these could well be using a much higher amperage. 

The dilemma you face would probably be solved only through a portable generator of sufficient capacity to service the current draw and run the charger, which is what you are doing by using shore power.  As you say, a non-smart charger wouldn’t be in the hunt in these circumstances.

Les

Go consult Phills best buddy Collyn Rivers (sorry Phill haha) in his book "MotorHome Electrics & Caravans Too", he sets out all this sort of stuff plainly enough.
Cheers.

Ken,

I have been looking at the specs of the 3600 CTEK and you are quite right.  The specs state that its charging cycle is limited to 75Ah batteries and less

The next one up is the 7A, which goes up to 150Ah on the charging cycle.  As you say, the 3600 would be inadequate. I have seen a table of initial recovery somewhere and I will try to find it again because that is relevant to your situation – trying to get the auxiliary battery up to full capacity.

Les,
Sorry but my scenario illustrates how I now manage energy recovery far more successfully compared to what it was previously ... the inadequate charging setup as installed by Trakka. Away from ac for more than a few days, Trakkas system was problematic. I agree the camping battery at 100 amps is on the small side for such a scenario but it's the largest battery that fits in the Trakka battery box and it is within the recommended range for my 30amp charger. Meaning I can also charge 2 batteries concurrently as well on its 2 independent charging channels within the overnight timespace. This smart charger delivers faster charging, marries well with my 2 AGM batteries that support faster & deeper & unstressed charging, hence I get that higher and faster energy recovery from an ac outlet overnight which I don't get from the stock 90amp alternator, nor the Trakka 12 amp charger and certainly wouldn't from a CTEK 3.6 amp. I've experienced the before and after scenarios, the difference is self evident. Bottom line is speed of recovery in a limited timeframe on a trip.
 
However I believe the ultimate solution is something like what John Figgis has ... from memory it's a 250 amp battery married to an alternator smart charger setup. That's it, end of story. Meaning he carries no solar setup, has little if any need for ac battery charging and can have lengthier stays without running out of battery energy. I know, I've seen the difference. All this with his 90 amp alternator charging the batteries faster AND fuller and all done automatically with smart technology. Embarrasses the rest of us, he's been doing this for many years.
 
OK, real life scenario is ... John and I both start our engines and both drive the same distance in a day. We both have 90 amp alternators, he has installed as well an alternator smart charger kit, I haven't. We both have similar size electrical requirements including a 12vdc fridge. He arrives at the destination and never worries about running out of energy because his charging system has delivered more AND higher level of stored energy in exactly the same time and distance travelled. By my having a 250 amp battery as well would help my cause but it still couldn't compete as my stock alternator delivers energy more slowly and to a lower 70-80% level only. It's an interesting real life comparison.
 
So for starters, I think you better up the anti on the CTEK 3600.
 
Cheers.
Ken

I'd like to dispute that one.
...............and I'd love to hear what the theory is behind it.
Thanks everyone for the info on that. There is a place at Mortdale (Sydney) that sells the 3500 for $116. I might pick one up next week.

I've got a XS 7000  that I bought in December 04 for $300. Only lasted a few months then died. Instantly replaced by Battery World ( they said it was very unusual) and this one has been perfect ever since. But I see them a lot cheaper than that now. They certainly let you know when a battery is crook, just never charge it up and everything gets hot. But when they are OK they charge it up and the little green lights work their way up to full.

i do not know what type of battery or its age but have you had a volt drop test done on it by a battery shop' the plates sulphate up with age and if the battery is left flat over a period decreasing its efficiency.

Hi folks,



Thanks again for everyone's help and advice.

I have been very busy so have not yet been able to get back to investigation/diagnosis of the problem and may not do so until next week sometime.



I have two batteries which I have been swapping in and out of the bus so have (correctly or not?) assumed that a faulty battery is not the issue.



Les I too have been taken aback at the number of responses to my call for help.



I'll post again when I have got my tools back out!



Cheers,



Andy.
