G1 very sluggish
I recently picked up a g1 electric cart for the local golf course and it was preforming fine until a week ago. It will roll fine till about 50 yards and gets very sluggish to the point where it is barely moving. If it sits a couple minutes it will do the same. This is what I checked so for:
-Batteries are alittle over a year old and old are showing 6.5 volts (checked individually) -All cables were changed with batteries and were cleaned along with battery posts -Changed 2 cables that were questionable going to motor and solinoid. Now I need some direction into troubleshooting the speed controller and resistor coil or ....can there be another problem. I hope its not much because not what to dump a bunch of money into old cart. Thanks for any direction in advance. Clint |

Re: G1 very sluggish
I checked the voltage out of speed controller and it was fine, the voltage to the motor is fine. The cart seems to run fine when the tires are lifted off off ground. After running cart about 30 yards it felt like it lost all power and the voltage to motor was still good but the motor was smoking alittle and was alittle hot. What do you guys think?

Re: G1 very sluggish
Just a guess, sounds like the motor brushes are not making good contact.

Re: G1 very sluggish
Yeah that’s I was thinking so I pulled the plastic covers by the brushes and there was a lot of black dust and some metal pieces fall out. I pushed the accelerator and I could see sparks in the motor so I figured that was the problem and I was not going to put more money into that cart. I had a friend that needed a couple parts so I gave him what he needed an I will use his cart at the course. The rest of my junk is sitting in a salvage yard. (RIP)
