Trying to troubleshoot 1994 36v. Have done all the testing I have been able to research and perform. Seems to be bad ground somewhere. To add to problem and making this impossible for me, is this: For 1994 all wiring diagrams I have seen show a resistor coil setup. This cart has a controller. I cannot find a brand, model etc, for this controller. I have a 1993 parts cart with same controller, and same wiring setup. Both could pass for factory install. Am I totally missing something here? Both are black plastic with ribbed housing. All help appreciated.
