Gregor:
Thank you for the info re the diff. I should have the tool you described (if I can find it ) left over from the days when L/R was a full time thing. I am reserving judgement on the prop shaft until I can drive the vehicle. It seems ok, but a cfm is in order. I have removed the spk plugs. They are gapped at .035 . My spec sheet says .025 for the 24V. Who had it right?
It was interesting to read the many comments re the 24V-12V voltage reduction. The use of diodes and a heat sink etc. would be the way I would expect a "solid state" device to be constructed, but finding the components around here will get you a little more than a "peculiar look" and the question what do you want that for? Will try the address provided by Sheldon. If one examines the principle by which a charging system works, it is obvious that tapping one of the 12's is not going to work unless you have a shed full of batteries.
