Is 6 volts to chassis normal?
I am confused about the chassis ground voltage of a 2002 36v V-glide. I bought it used a year and a half ago, put 6 new batteries in it, and later installed a new D&D 42A high torque motor in it. It has been working just fine.
I was installing an automotive USB charger adapter in the cart last night and was checking various voltages and am now scratching my head. There seems to be 6 volts potential to the chassis all the time????
Using the standard battery layout on the pictorial wiring diagram for the V-glide, with plus terminal of battery number 1 being red wire (+) to the forward/reverse switch, and the minus terminal of battery number 6 being black wire (-) to motor terminal S2, and also the white wire (-) to the charging socket, here is what I found.
Voltage from + batt #1 to - batt 6 is 36 volts. Good!
Voltage from + batt #1 to chassis is 30 volts ???
Voltage from - batt #6 to chassis is 6 volts ????
I see that the chassis is electrically isolated from the wiring and is not used as a system ground like in a car, but I thought the voltage from - batt #6 to chassis should be zero. But it checks 6 volts, no matter if the switch is on or off. I checked current draw through various cables and the most I got was 12 milliamps (leakage?), so its not like a serious short to the chassis.
Is this 6 volts to chassis normal?
I haven't started tracking it down yet, but will very soon, plus I have a controller and solenoids and reversing solenoid to install, and don't want to ruin them on start-up.
This might not have anything to do with it, but when I was hooking up the USB charger, I found that the lights were wired to + and - of batt #2, so they only had 6 volts. No wonder I thought they were burned out. I switched them to - batt #6 and + batt #5, to give them a full 12 volts. I also hooked the USB charger (made for a 12 volt car system) up -6 and +5 to give it 12 volts. Should these have been hooked up to +batt #1 and -batt #5 instead? Doesn't seem like it should matter since there is no chassis ground being used.
Any comments would be greatly appreciated!
Thanks, Lloyd
