I hooked up an extra ground wire to the engine arm, I followed bluebimma's diagram shown here:
I thought the original ground wire was not grounded, but it turns out it was there all along, but I still hooked up a ground to the engine arm anyway. Here is what I did, you can see the original motor to chassis ground wire a lil beside the new black ground:
However, this did not solve the problem. Unless I have to mount the extra ground to the same post as the neg battery cable... Like bluebimma did here
