did you check the sonic weld by the reverse speed switch?

No where is that at? In the wire harness?

The only sonic weld I see is the black/white wire coming off the micro switch 1, welding to the red wire. Is this the one you are talking about?

If you look at the diagram I posted, is where the 1/2 speed resistor splits from the white wire.

Found it!!!
OK, this may seem like a nutty question, but what do I need to test about that sonic weld? Do I open it, check the diod if one is present, solder it? I have not dealt with those before. I know I should know by now but I don't.

It is a glorified crimp connection that is supposed to fuse the wires together.

I would just pull on each wire to make sure the connection is good.

There should be a resistor coming off that connection.

That is the most likely place to have the throttle signal drop out.

OK, after fiddling and fussing with the wire harness and sonic weld the cart is dead and no longer has occasional run time. SOOooooooo I ordered a new wire harness.

Any tips, tricks, help, ideas, thoughts......at this point the only components I haven't changed out are the OBC, key switch, and battery light.

If a cliff were near by I would start pushing it that way!!!!!!

If you refer back to the diagram I posted, just connect the green wire coming from controller terminal #2 directly to the black wire that goes to the MCOR.

That will completely by-pass the half-speed reverse micro switch and send the throttle signal directly to the controller.

All of those wires will be near the micro switch #3 You are working with.
