I can not find any diagram. I tried the best I can to troubleshoot. If I ground the - side, blue/white wire, the solenoid will click when I turn the key on. The controller still will not go. Is the OBC or the controller bad. Bad ground. Is there any troubleshooting flow charts out there. Mine has no tow switch, only one solenoid, and the big black connector on the controller has 3 rows of connections, not 2 like most diagrams show. I am so lost. The speed switches seems to be working, not sure, but when I push it down, I get 48 volts to on the green/white wire back at the controller. Something is stopping the OBC from letting the controller to run I think. Any ideas on what to jump, or measure would be great!
