Happy to answer any questions or provide more detail.
Will post the circuit diagrams for charge panel if anyone is interested.
The three battery systems Main (cranking), Auxiliary 1 (inverter) Auxiliary 2 (lights, fridge etc) can be charged independently 4 different ways.
240V mains, 240V generator, solar panel or alternator.
Trouble is the 'operator' needs a degree in engineering to work out how to use it :-)
PS: thanks for the feedback on the loose axle shaft bolts.
