36V marathon wide open throttle
New to the golf cart world guys, however have a pretty decent electrical background. I have what I believe to be a 1993 Marathon cart I bought used. Brand new batteries, brand new solenoid, and brand new pots meter. I have been thru the battery checks/test and also the pots meter. Everything appears to be working as it should. And if I am reading an old forum on here correctly the speed controller is testing good as well. My question is, since I bought used is it possible that it’s wired wrong/backwards? I have full throttle in forward and reverse no matter how much the go pedal is pushed. As soon as that solenoid clicks it’s wide open!! Cart is a blast to ride, just a little hairy parking in the garage 😭😝😂. Any help would be greatly appreciated.

Re: 36V marathon wide open throttle
Not sure I can offer a diagnosis, but I'm dealing with the exact opposite right now......full pedal and nothing. I "think" I've diagnosed my potentiometer as the culprit. The following link to a previous thread had the electrical troubleshooting PDF for your cart (same year as mine) that you can download. Super helpful for me.
https://www.buggiesgonewild.com/show....php?p=1636724 If that doesn't work, Google search this document "90-95 MARATHON ELECTRIC TROUBLESHOOTING.pdf" and the thread should pop up. Blake |

Re: 36V marathon wide open throttle
The throttle output of the Marathon should be 0-5000Ω(0-5K).
Both the potentiometer (signal device) and the controller can be found in 0-5k and 5k-0 configuration. The could have a mismatched throttle potentiometer and controller situation. |
