Default Melex 212 electrical problem

I have a Melex 212 which I bought from the local little league team as a donation. The car ran, but had front end problems due to a crash. In fixing the front end, the repair shop broke the pinion gear in the rear end. To make a long story short, I replaced the rear end with a club car rear end and wired the motor as a series motor with the original melex electrical system. Everything worked find. But it has now stopped working. I can find no lose wires, the batteries are charged and nothing seems burned. I have downloaded wiring diagrams for a melex/ezgo resistence cart and everything looks to be ok. I do not know how to test the various components. It acts like there is a fuse that burned, but I cannot find one. Any suggestions?

Turns out it was a solenoid. Fixed it and now it runs great.

Sorry we didn't see this soon enough to be of help but, glad to see you fixed it on your own. I have noticed the ezgo and CC mounts are the same width..how easy was the instalation?

Other than a few cuts from the screws it was easy.
The only problem I have now is that the resistor coils seem to be getting very hot. Is it possible that the new motor is pulling more current than the original melex motor and I am therefore exceeding the design specs of the resistor coils? How do I check?

The coil is a resistance coil which controls the amount of electricity that goes to the motor. At low speeds the coil gets very hot because most of the electriciy is going through the coil. The same set up is used in the older exgo carts.
There are many electrical disgrams on the web that explain this in the melix and the exgo carts. As far as the clicking goes it probably is because your batteries are low and it is the solinoid is not getting enough power from the batteries. Charging of the batteries to full charge probably takes overnight. Get a hydrometer from a auto parts store and chech the batteries to see if they are actually fully charged. My ezgo card takes at least 6 hours to fully charge and it is wired just like the melix. you might also have your charger checked at a golf card store to see if it is actually working.
