Questions & Answers
The problem I had is that I was not getting the full voltage through the F/R switch.
Since I had two F/R switches sent to me by mistake, I had already swapped the switches out before and obtained the same results.
After tightening the 9/16 bolt the power went through the switch but as I was driving the cart, it would stop and go. I would have to play with the switch by wiggling it back and forth.
I realized then that something else was wrong and dismantled the F/R switch.
I found as you can see in the slides below, that the cooper electrodes were sitting below the surface of the composite base by .005 to .010 thousands of an inch. The electrodes are also not round but oblong.
The electrodes on the rotating switch of the assembly are also not lined up when you rotate the switch (See drawings in slides) creating part of the electrode to sit on the composite material.
This situation creates a .005 to .010 gap between the electrodes.
This situation is what was causing getting no power to through the balance of the system.
Therefore, by tightening the 9/16 bolt at the front of the switch, is not the correct solution because all you doing is flexing the entire switch creating premature wear and power fluctuation.
Root cause are the electrodes.
1. electrodes in the main base (Switch) are sitting below the surface.
2. When rotating the switch, because the electrodes are oblong and not oriented properly after the switch is in the F/R position, they sit on the composite material and have a gap.
