That was it...at least partially.

The MS for the buzzer got fried (that would explain the smoke :-). So I moved the other MS over to the other side and wired it appropriately. I am now getting a click on the solonoid and motor running in reverse. As well as solonoid click in forward, but no motor. I suspect now it is a contact in the Forward/Reverse switch that need to be cleaned, since the solonoid is getting voltage.

Live and learn, right?

By the way...I am getting some bluish arcing on the speed control board from the brush and contacts as I apply the accelerator. Anything to be concerned about? Is that normal for this type of older cart?

I will take some newer pics soon, but here are some of the original state of the cart a couple of months ago.
