Cart won't run....resistor is hot ???

fiddlerabbit · 01-03-2016, 02:18 PM

I have a 2002 club car DS IQ lifted. The cart will run about 23 mph, but I have had overheating issues lately, and finally gave in to the understanding that I need a torque setup for my application. So I have purchased a new motor, controller, and solenoid but it hasn't arrived yet. In the mean time, my golf cart quit running. I thought the motor or controller must have finally burned out. I then pushed the cart back into the garage and kept smelling something hot/burning. So, I crawled up under it and found a very hot resistor on the solenoid. This was odd because the key was in off position, switch in neutral, and the cart switch was in "tow mode" position. I unhooked the battery cable going to the solenoid and it cooled off. What does this mean? Do I have a bad resistor, or perhaps a bad solenoid? If so, is my used motor and controller still okay for a friend wanting only speed in a cart. I am very new at golf carts. Any suggestions would be appreciated.

Does anyone know what causes a resistor to get hot is most cases?

If the solenoid does not close the large contacts the cart will try to run all the high amps through that resistor. I'll re read the first post and see what you said.

Ok your solenoid is likely shot. The controller may be bad the motor is likely ok. I'm not an expert here but this is what it sounds like to me. I would have to get hands on the cart to know for sure.

How do I test the controller?

Replace with known good.

I actually have a new one coming, but I would like to know if this one is good before I give or sell it to someone. Is there any other way to determine if it is okay?

When you get the parts in, change the solenoid first. If the cart works then the old controller is OK. Be SURE the batteries are unhooked while working on this stuff. Put cart in TOW first thing.

90% of the time it's a bad controller that causes the resistor to get hot.
