I've got a 1997 EZGO DCS 36 volt (six 6-volt batteries). When I got it, it had no accessories on it and now I'm loading it up with cool stuff like stereo, lights, etc. However, the whole 36 volt/12 volt thing is turning my mind into a pretzel.
I have a 12 volt stereo that I'd like to hook to the ignition switch. I also have a 36 volt meter that I'd also like to hook to the ignition switch. At first I thought it wasn't possible to do both because there is only one set of terminals on the ignition. But then I started thinking that the amount of voltage is really determined by the ground. So if I run a hot wire from Battery #1 positive to the ignition, can I run one wire from the ignition to the stereo and another to the battery meter as long as I make sure each of those accessories has the proper grounds?
So the 36 volt accessory would be grounded to Battery #6 ground (6x6=36) and the 12-volt accessory would be grounded to Battery #2 ground (2x6=12).
Am I making any sense? Will this work?
