You didn't describe the problem, but if it's wandering or going hard over and staying there or similar, you have nothing to lose by opening up your current unit.

If you can solder, redo all twelve leads on the big black power transistors (4 with 3 leads each).

That may get you going again.

Hi Steve B

The problem is we can't get 12 volts to the electric motor (wheel pilot).
Cheers, Angus
