No juice to solenoid
I havea 99 ezgo 36v cart I was repairing a broken frame and had to reroute part of the wiring. With the original brown and green wires was a 36v hot wire, a 12v hot wire from a voltage reducer and a ground wire from the battery pack..when I cut the wires I didn't disconnect the battery pack..the wires arched and 1 blew the bulbs on my headlights which were connected to the 12v hot wire and through a headlight switch all aftermarket. The 36v wire went to a battery check gauge. After repairing the frame and splicing wires together I have no power to the motor..I get no click from solenoid or any sound. I've looked for fuses and cannot find any in the wiring harness. I have 36v at the charging plug. Batteries are fresh and charged. I've tried jumping across the solenoid and nothing. Does anyone have any suggestions on what to check? I need help!

Re: No juice to solenoid
Which drive system does your 1999 cart have?

Re: No juice to solenoid
Not sure. It does have the Manuel fwd/rev switch under the seat. How can I determine which drive system I have?

The first place to check is for full pack voltage on the smaller of the three wires coming out of the backside of the charge receptacle. |

Re: No juice to solenoid
There is a rod so it's a series drive. I'll check tomorrow. Football tonite. But thanks so much for your help. I'll let you know what I find. Would I put the + lead from my volt meter to the the small wire and ground the other lead to read the voltage?

Re: No juice to solenoid
Unless specifically stated otherwise, the negative test lead is connected to the battery pack's main negative terminal for all voltage measurements.
The cart's frame is not, or at least shouldn't be, connected to the battery pack, so golf cart is an non-grounded system, so every electric circuit requires two wires. One from the battery pack and one back to the battery pack. |

Re: No juice to solenoid
Thanks. I'm getting no voltage from small white wire on back of charging terminal. I pulled the ignition switch and have no current on either side also.

Re: No juice to solenoid
It looks like the power goes through a switch on the throttle pedal. I started trying to pull the switch and got the four bolts removed that hold encase the switch but can't get the box to break loose from the frame. Am I on the right track??

The reed switch probably got trashed when the 36V wire arced. |

You are getting ahead of the troubleshooting. No voltage at the small wire has to be fixed first, then the keyswitch if need be, then the pedal switch if need be. To access the pedal switch, lift the floormat and go in from the topside of the box. |
