Re: Low voltage to frame?
That's because an LED draws only a couple mA to light up.

Re: Low voltage to frame?
Well, you guys are pretty smart! Checked voltage to battery plastic case, nothing. Zero volts. Checked all battery caps, Had a can of battery cleaner, sprayed batteries, cases, hold downs,as much as frame I could reach from top and bottom. Then washed all down gentle spray. Dried top of batteries then put back in run mode. LED BATTERY GAUGE STARTED WORKING! No longer stays on, and key switch working. If any voltage leaks are there they aren't registering. Thanks again to all, but got to say, pretty weird.... I guess that's why the newer carts use more plastic rather than metal trim.

Re: Low voltage to frame?
We have been around too long. I think if you added scotty,s volts and my ages together we could probably beat Noah. It's surprising what you can pick up over that many years!
Now I sit waiting for the flack from the other two 😆 |

Re: Low voltage to frame?
That ghost voltage is part of why electric carts cant have any frame grounds. Eventually there will be enough current moving through the frame to cause an issue and it also causes galvanic corrosion.
Good that you found it. Keep those batteries clean! |

It’s worth noting a little voltage may be normal, but it’s always worth looking into. I’ve had bad controllers and motors cause 48v to go into the frame before. Loss of isolation between the HV system and the vehicle frame is bad. In a golf cart it will likely just give you a nice “tingle” but in higher voltage applications like cars it can be very dangerous. |
