Jump starting 24v systems

[willeg]

Can you jump start a 24v system with a 12v truck? If so, how?

Never heard of it being done, and I'd be a bit wary of trying - too much risk of frying the electronics on the donor vehicle with 28V alternator output if you ever got the slave running.

You would have to use a 12V to 24V converter; don't know if there's one out there that will handle starting amperages.

Either way, it would be my last resort.

Good old Dad ran two 12v batteries on his pickup trucks, mainly to let a camper draw off of one without draining the other. But, it also helped when we needed to jump a 24v starter on a diesel bulldozer - pull both batteries out, and tie them in series.
