intermittent electrical prob

golfcarwop · 06-29-2010, 09:09 AM

I have a 99 ez-go electric and I am having a intermittient power problem. I was driving the cart yesterday, and it just quit, when I got it home I started testing all wiring. Two things seemed weird to me, 1 all the posts on the motor were live, 38volts, power going into the controller and coming out all wires to the motor. 2 I could here the soleniod clicking when I steped on the pedal. Then this morning hopped on and it ran like a top no problem, and I can't get it to repeat the promblem in hopoes of narrowing it down. Any suggestions would be greatly appriated!

If it quit while running, I would look for a bad battery or F-N-R switch connection.
If you had power to the motor with the key off, your solenoid is sticking and should be replaced.

Hello!

First, we'll need a little more info about your cart.
Is it a Series, PDS or DCS?
How old are your batteries?
What type of controller do you have (stock or aftermarket)?

With a little more info you'll get a lot more help!

It is a DCS, it has all new interstate batteries, stock controller, as far as i know the only things that have been replaced ever are the batteries and soleniod i just put in.it was purchased from a private owner who claims to have never had any probs with it. Until I get the hang of what info is needed to help me with this, please be patient, I am a newbe at the cart game. Thank you for your time.

Sounds like after it cools down it works, that's indicative of a bad controller, especially on the DCS carts.
I will let others chime in here on this issue, but that's my call on it.

If you just changed the solenoid, did you also change that pesky resistor assembly that spans the 2 large posts of the solenoid? They fail.... alot. especially if you switch from forward to reverse while the cart is in motion.
