Starter motor.
I too had that problem however the reason may well have been different. I was running a 6V starter in a 12v conversion and was concerned about the severe impact that was made on engagement. I converted the starter to12V by changing the field coils. It made 1 start and I was delighted at the moderate even gentle engagement. That was it, the only start I got. I removed the starter and figured the bendix had become jammed too tightly in the home position.So had it ground plus put steel spacer washers on shaft to prevent it going all the way home and jamming. Again got 1 start. I then figured the double voltage had caused the armature to spin so fast that this situation didn’t develop. I am now about to change the armature for a 5/8 shaft with a new bendix retaining my new field coils.
There is a new type of starter which costs about the same as I’ve spent so far and mostly wasted. I did not know of it when all of this started. Pun unintentional.
