Trakka Owners - Wiring

I have got down to the source of the starter solenoid not pulling in.
I removed the wire from the starter switch at the solenoid terminal 50 and applied 12 volts from a good battery via short leads.  The solenoid pulled in and the engine started immediately.  Prior to that, all I was getting was a mild 'clack' from the solenoid, which wasn't enough to energize it.
I had previously looked with grave suspicion at the wiring coming out of the ignition/starter switch.  Many wires have been cut and had other wires added in.  The splices are soldered but could well need re-soldering to ensure good continuity.  If any Trakka owner experiences problems, this will be a mandatory check.  These changes look to have been part of the original Trakka wiring which, in mine, leaves a bit to be desired.  Mine was the de luxe conversion, which included an alarm.
I don't want to get stuck again with a solenoid problem, so I am putting in a waterproof relay at the solenoid, using the existing 50 terminal wire as the signal line.
