Okay, I can’t get my 360La engine to start

How do I test it?
Well, you might be able to find a parts store that can bench test it for you and see what it is drawing for power.

It would probably just be easier to buy a new replacement starter and go from there.

It the battery is good and you are sure of it, then the starter is defective and it is drawing to much power to operate and needs to be replaced.
