Jumping A 24 Volt System

It consists of 2 x 1000 cca 12 volt batteries connected in series to give 24 volts.

Jumping a 24 volt system. In either case if a vehicle with a 24 volt battery needs a jump start it can be a headache. 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. 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.

Position the 12 volt truck as close to the 24 volt truck as possible. Orientate the vehicles so their batteries are as close to each. 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. Some 24 volt systems use 24 volt batteries while others wire two 12 volt batteries in series.

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. If this is the same way your 24 volt system is connected the starting procedure is quite simple. The battery system is connected as in this diagram which is the most common setup for 24 volt systems in trucks and buses.
