General question about golf cart ground wire
My 1987 electric CC DS is not grounded to the frame, I was wondering if / why all golf carts in general do not use the frame as a common ground like cars do ?

Re: General question about golf cart ground wire
Safety. If the frame were used as a ground and became compromised, when you got on the cart YOU would become the ground.
PS- Also circuits could be miss-routed. . Last edited by tag50; 04-29-2016 at 03:30 PM.. Reason: PS |

Re: General question about golf cart ground wire
Electric vehicles Don't ground the power system to the frame for safety reasons.

Re: General question about golf cart ground wire
48 volts with all the amps of 6 batteries will light you up big time. Don't ever try holding one hand on pack neg and the other on pack pos. It very well could kill you dead.

Re: General question about golf cart ground wire
There are two safety issues. One is shock - Yes 48V is dangerous. The other is high current discharge if you create a short. Both are reduced by not grounding the power system. Most electric cars and Hybrids are running over 300V so they are very dangerous. They are required to have a disconnect that first responders to an accident can hit to isolate the battery system in the event of a crash.

Re: General question about golf cart ground wire
The system us called an isolated ground and it's not uncommon in higher voltage systems that have a high amp potential...FYI...the Hybrid safety disconnect is always located in the trunk.

Re: General question about golf cart ground wire
Interesting, thanks for the answers .. I wasn't thinking about the high amp draw angle, good point, so even if "earth" ground doesn't affect a DC circuit there is still a possibility that someone could become the circuit ground IF the battery ground itself was lost and the batteries and frame got wet (to complete the circuit) a person could become the conductor that completed the series circuit to the motor ... better keep a closer eye on my cables ;) Thanks all
