EZ GO Marathon Resistor Coil

[tliebks]

I have an early 80's Electric Marathon that will not move but will lurch every now and then. I have tinkered with it all day checking the solenoid, microswitches, forward/reverse switch and have found nothing wrong. Would a bad resistor coil cause this?? Did not want to order one until I got some advice??

A broken one could.

I can't see that is broken but it is sure is rusty. Would that do it??

Well, considering that rust will cause higher resistance as you are losing some of that little metal bar that transfers the current. They are cheap anyway, throw a new one on and see if it helps......it certainly couldn't hurt.

This might make you feel like you are doing something towards solving the problem but you aren't. All resistor coils are rusty. Hit em with a wire brush and see if any of em are broken. If not, look elsewhere for your problem.

MOst likely the problem is in poor contact on the speed wiper board located at the end of the throttle linkage. There are large copper contacts and a moving copper contact on an arm moves across the stationary ones. check the condition and fitment of the wiper and stationary contacts. Clean them up with sandpaper and file.

I will do that tomorrow. I checked for continuity on those contacts but did not clean them. They are really a pain to get to. Thanks for the help!!

If it's real bad you can buy new contact buttons and wiper arm. It's probably the biggest trouble spot in the system

I live in the boonies. No golf cart supplier close. Anybody you recommend to order those from in case I need them?? Again I'm new to this.

Does the solenoid always click when you give it gas and it's not moving?

Click on Sponsors and there are a number of folks that may carry or be able to order them. I always try and support sponsors, even if I can get them a little cheaper on eBay. Service, and support of this site is invaluable.
