Bedford was flat the other day (someone left the isolator on, not me!) - we ended up taking the batteries out and charging them individually, but what's the correct procedure for jump starting a 24V veh from a pair of 12V vehicles?
If you just parallel each battery with a car battery (still in a car) using two sets of jump leads, if an electrical connection is made between one car and the truck chassis or both cars, at least two batteries are shorted! Could remove chassis earth connections from the cars but then why bother with jump leads, might as well remove the batteries.
So, have I missed something?
