I a have an electric club car and there is a clicking in the rear in when I go forward but not in reverse.

Is there a sensor that mercury sensor that may be out that would cut power down hill that is messed up from lifting the rear end up while installing lift?

Reguardless where the fwd or reverse swith was located. I was able to get it onto the trailer in reverse however, now the cart won't go in any direction. What or where is the most likely starting point for...

I have a 1999 Nissan Pathfinder and it starts and runs perfectly. When I put it in Reverse though the engine just rev's and when I put it in Neutral it drives forward. It also doesn't roll backward at all....

I hear a clicking that is similar to a rock in the tread. However, you only hear it moments prior to stopping. You do not hear the noise when starting back up from the stop. It is not present while driving either....

The forward contact welds closed on the lift. The release spring is the same strength as the reverse. The contacts are new. It current arcing does seem more than reverse.
