The car will not move but the controller is good. The car moved as it should briefly when I connected the green wire (above charger) to the red wire (small red wire coming out of long yellow wire). Since then it has not moved. These 2 wires were not previously hooked up. All connections are tight. I really need some advice on how to diagnose this. I'm guessing the problem is something small since everything worked briefly. If anyone is willing, I can pm you my phone number.
See that fuse? Never use steel hardware (nuts, washers, etc) in the high current path. That is a certain failure point. Clamp the lugs directly to the fuse tabs. And what is with drilling Anderson lugs to use for battery terminal connectors? Bad, very bad idea. You're lucky it didn't run.
Sorry to be blunt, but your wiring really needs help.
Thanks for the reply! I bought the car this way. Perhaps someone here can take some time and help me do it right. I'm kinda new to ev cars but I am familiar with the citicar but is totally different than this leopard.
I have to agree with Major on this one. There's a whole lot of fail in that wiring job. It looks like an accident waiting to happen. It likely wouldn't take much in the line of materials to clean it up, just a lot of labor. In the process you could draw a full schematic for future use and troubleshooting.
Two other problems (by no means is this list exhaustive):
1. no precharge resistor across contactor for the Curtis controller
2. low current ring terminal underneath high current terminal on 3rd battery, top row (first battery shows proper stacking).

I took off the hardware in between the fuse. The car now moves in forward and reverse, however there are sparks inside the motor. It appears the motor is original as its mounting connections are rusty. What should I check for?
Personally, if it were mine, I think I would start by tracing each wire one at a time, and make a wiring diagram. Assuming that everything wiring-wise makes sense, using a volt-ohm meter I would troubleshoot it from there. In the process, I would clean up the wiring making sure everything is mounted properly (including batteries) and all wiring is routed properly and securely.
It's pretty difficult to troubleshoot something like this remotely.
How ling have you had it and how long was it working??
