Re: How do I test a starter motor?
My Two Cents: I've had two units, and tractor, and a boat, that I thought had bad starters. As it turned out, NEITHER starter was bad. The tractor? Safety interlock switches came apart all by themselves. The boat? Battery cable corroded in the salt climate, and looked like it was cut all the way through. Could not easily see the damaged area, but an engine guy found it in under 30 seconds.
So, test your starter the cheap and easy way: Take it out of your tractor. Hook it up directly to jumper cables and your CAR. If the Bendix drive kicks out, you know the starter is good. Look for other problems.
