Starter won't turn over

clange · Oct 5, 2016

Well, I couldn't get my 8n to run so I isolated the problem using the archives of great knowledge on this board and figured out that I either had a bad coil or burned up points. Thought that this would be a great opportunity to change out both as I never have done so in the 12 or so years I've owned this tractor.

Got everything changed out and went to start the tractor and it won't turn over, so I decided to pull start it. She started and worked wonderfully. Great - one issue solved!

But the starter is still an issue. I have a healthy 6 volts at all my connections, but I notice that when I press the starter button it dips down to near 0 volts. It is a brand new battery, so I'm wondering if I have a bad starter, starter button, or solenoid, or something else. Any ideas that I might be able to try this weekend?

Whack it a couple of times with a hammer. If
that doesn't work, jack up a rear tire and
turn the wheel.

Your bendix could be stuck on the ring gear.

If that doesn't work, jump it. ( see tip #

Thanks for the quick reply, Bruce. I can try those steps tomorrow.

you failed to mention where you saw 0v on that volt reading.

clange · Oct 6, 2016

Good point.

I measured the 0V at the starter button. I had my ground lead at the same location that the battery is grounded - on the steering box.

You do realize the starter button is a ground switch. You measured from ground to ground.

Well, the good ol' whack with the hammer did the trick. Rapped it lightly a few times while pushing down the starter button and she roared to life. That was way too easy

Thanks again for the help!

Got it going again Soundguy with the hammer trick Bruce posted, but now I'm curious about your ground comment. I would see 6 volts at the terminal where the wire is connected to the starter button and it would drop to 0 volts when I hit the button. I figured the button must be a ground that creates a path for the circuit to be completed causing the solenoid to close and energize the starter. Is that what you meant, or am I way off base? Should I not have measured 6 volts there until I pressed the starter button?

(quoted from post at 22:35:02 10/05/16) Whack it a couple of times with a hammer.

I call that "percussive maintenance".

Like I said, with button pushed ground to ground.

Thumb button I nothing but a switch to ground. Relay is internally hot from battery, thumb switch is just completing the circuit.

You should measure bat volts at the insultated switch terminal, before the bomutton pressed
