EZGO Golf Cart Electric will not run

The batteries are fine, fully charged giving me a voltage of about 38v. I arced across the solenoid and the cart moved. It was working fine until it was parked. Father-in-law that drove it passed away and the cart hasn't moved since. Any ideas on what to replace or do? I replaced the solenoid, cleaned the terminals, cleaned the reostat on the accelerator, tested the switch. What is the small two pole plastic item that sits next to solenoid supposed to do and could it be the problem? Is it a diode?

Thanks for any feedback or advice you can give. I am still attempting to determine the year of the cart. Is that easy to do?

This page may help you figure out the age and model of your cart.

You say the cart moved when you arced across the old solenoid then you installed a new solenoid. Is the new one pulling in/closing?

The wiring system is pretty basic. It does sound like that piece you are describing is a diode and if it is..... it is there to suppress the arc from the solenoid when it unpowers. Maybe after you find out the vintage and the model we can find a wiring diagram and help you more.

Found the site difficult to follow but I believe that the cart is a medalist and a 1979 model.

Do you have a electric/voltage tester?

Is the new solenoid you installed being pulled in/energized? That's sorta the first step in the puzzle and since you mentioned that it moved when you jumped across the old one... This leads me to think it's the solenoid or something upstream of it.

What does the pulled in refer to. The solenoid is a brand new EZGO part. I have a volt meter. Upstream from that is a small two pole item about two inches wide, about an inch and a half tall and about 3/4" thick. What do you think that might be.

The solenoid is basically an electrically powered switch or relay. By pulled in I mean "on". When energized or pulled in current should be able to flow between to the two big lugs/bolts on the solenoid. A small amount of current is applied to the solenoid's coil (an electromagnet) that closes the switch to let power flow between the big bolts. When power to the coil stops the switch opens, cutting off the big power going to the motor.

There are several things that could cause the solenoid to not work; bad solenoid, incorrectly wired, bad key switch, broken wire, loose connection.... It's a simple & inexpensive part that must work in order to send power to the motor.

Hi. I have similar problem with my ezgo electric cart. The vin is 801125 2010341
Is it a 1980 cart? Where can I get the correct wiring diagram? Any help would be appreciated.

Welcome to the forums.

The serial number isn't providing me any needed help. Look up in post #2 and there is a link there.
See if you can indentify what model you have.

Welcome to the forums.

A little different problem than the others in this thread.

What you need to find out is if the motor is humming (not turning) or if the motor is turning and you've lost the transaxel.

I have a similar problem on a 97 EZGO as Bruce(Mfg J2897). Batteries are at 37.5v, the forward/reverse switches are cutting through and the reverse beeper is on in reverse. My father in law did some 'testing' around the little circuit board below the solenoid and something 'sparked'. Looks like it has a pair of diodes and a resistor. The solenoid does not kick in with throttle. Is there a way to jump across one or both of the solenoid small terminals?

I can see by the page views that this is a hot topic. Having more that one member problem in a thread creates confusion. I'm sending this thread to our searchable archives where it will be always available for reference.

If you need help with a cart problem start a new thread. Please post the make and model. Don't post without it as it just wastes time.
