Well, I spent another day on the cart. The on board computer has no blue and no white wire. The pin outs on the the controller are very close, but not exact. It is aftermarket with an adaptor to hook it up. I gave the model of the controller in the previous post. I can not follow the flow charts because after the first step, it said to go to the blue wire on the OBC. It looks like the Blue wire and the white wire are the B+ volts for the computer. I do not have those colors wires. I did check the speed control ( gas pedal) and I have the voltage on one side 3.5 and when the pedal is pushed it does go to zero. that is to tell the OBC not to be in sleep mode. And the switch does switch the B+ back to the controller when I here the small switch click, so it is also good. That would be the blue wire from the key and then the purple wire back to the controler. that all is good. On the OBC I have Brown, Green, yellow, Red, and the grey going up to the charge socket. On the yellow wire on the OBC, I should have 5 v from the controller, I have 0, then .6 when I push the pedal. I am reading only 500 ohms from the yellow wire to ground at the OBC with the controller unplugged. I am not at the cart now and it may have had an orange wire on the OBC too, I cannot remember. I tried to reset the OBC as per the manual. The controller has 48v on it pin 1. I can ground the one side of the selonoid and get it to key up and put the 48 on the controler. still no movement. The reverse buzzer does work, and I checked the Forward REV switch as it does switch voltage at the controller when I push either. I am thinking the OBC is bad but not sure. Is there a way to bypass it and just have the controler in line. I can take pictures or what ever can help. Tired for today. Aftermarket and the adaptor is throwing me off I think. Greg
