No power, no clicking, no nothing.

Okay, checked the charging port, that seemed okay. The Diodes, I dont know how to check to see if they are good, but I was only getting 4V to the wire on the diode that goes to the ignition switch. I ran a line directly from the power side of the solenoid directly to the diode and now the solenoid IS engaging and one time, I actually got power to the rear wheels, but after that it stopped responding. I still have the solenoid engaging now in both forward and reverse, but no power to the wheels. I do believe the motor is good now as I was able to get power to the wheels once. I am really suspecting the "gray magic box" that I believe is referred to as the controller. The solenoid, ignition switch, and batteries are all new and the motor did come on and wheels spun one time. Is there a way to check the controller?
