0% Battery voltage on handheld
I have a 2003 club car ds in my shop and it had a bad controller in it. I ordered a new controller. I tested A1, A2, F1, and F2 against the motor case to make sure i didnt have a short in the motor. Everything came back ok. Installed new controller and nothing. No click of the solenoid. Hand held shows both switches in the MCOR are working as expected. Key switch shows that is is working as normal. Tow switch is working as normal. Forward \ Reverse switch shows working as normal with buzzer in reverse. The only faults on the handheld are low battery voltage which shows 0. I was wondering is someone could give me some insight on where the voltage comes in to the controller that gives it the readout on the handheld. Pin 5 Light blue - off the obc is providing 48 volts to the controller with the charger unplugged - as normal. I am having a field day with this cart. Any suggestions are welcome. Thanks in advance.

Re: 0% Battery voltage on handheld
Might check the pre-charge resistor on the solenoid. Maybe it's burned out? That resistor is often damaged if a controller fails.

Re: 0% Battery voltage on handheld
Does this cart have turn signals on it by any chance?

Re: 0% Battery voltage on handheld
"New" controller?
or "Rebuilt" controller? Seen this numerous times with rebuilt controllers. |

Re: 0% Battery voltage on handheld
Controller is new and not a refurb. The precharge resistor does look as if it may have an issue. The plastic coating that was over it has melted away.

Re: 0% Battery voltage on handheld
no turn signals on the cart. i checked the temp of the resistor and it is getting up to about 106 with the cart in run and the key on.

EDIT: Just re-read your first post and realized you'd already tested the motor. In this case the controller is suspect. |

When i tested the motor i didnt check continuity from a1/a2 or f1/f2. i only checked from those posts to motor case. I will go back and check just to make sure. |

Re: 0% Battery voltage on handheld
The old resistor did look suspect so i put on a new resistor but as soon as i connected the battery it started getting hot so i disconnected the battery.
