switch in reverse moves cart forward

The diode is good or the cart would not have moved when F/R lever was in R.

To get cart to move in either direction, 36V has to be applied to Pin-5.

In the F position, the voltage passes through the top switch on the schematic to the keyswitch, then on to the solenoid coil, where is is paralleled to Pin-5.

In the R position, the voltage is passed through the bottom switch and parallel to two places. The orange wire goes to Pin-4 and tells controller to go into the reverse mode of operation and the diode passes the voltage to the keyswitch, eventually getting to Pin-5 and telling controller to run.

AS previously stated, when the cart moves forward when direction selector is in R, either the voltage is not getting to Pin-4 for some reason, or the controller is being told to go into reverse mode and is not doing what it is being told to do, so the controller is bad.

Since it is intermittent, try unplugging the connector on top of the controller, spray cleaning and reconnecting.

Don't you need to come to South Carolina? Thanks I have even opened controller. Will give a try
Thanks so much
