Jumping a 24 volt system. Jump starting a 24 volt system from a 12 volt system won t work if only one 12 volt battery is available but if the 12 volt truck has two batteries it becomes possible to produce a 24 volt supply. In either case if a vehicle with a 24 volt battery needs a jump start it can be a headache. Orientate the vehicles so their batteries are as close to each. If this is the same way your 24 volt system is connected the starting procedure is quite simple.

It consists of 2 x 1000 cca 12 volt batteries connected in series to give 24 volts. Since the power of a 24 volt system will overload a 12 volt one in another vehicle you will need another 24 volt battery to provide the power. You could how ever put two 12 volt batteries in series and then use that set to jump your 24 volt system there are two possible waysin any case do not use one 12 volt source to boost both. Some 24 volt systems use 24 volt batteries while others wire two 12 volt batteries in series.

Some 24 volt systems use 24 volt batteries while others wire two 12 volt batteries in series. Since the power of a 24 volt system will overload a 12 volt one in another vehicle you will need another 24 volt battery to provide the power. The battery system is connected as in this diagram which is the most common setup for 24 volt systems in trucks and buses.
