The original subject was "Re: 430 starter problems".

I found this site after a search and am responding to this old thread, because I experienced the same problem in the same way. I did all that was suggested already, including bypassing the starter switch, etc. The battery is good. The starter appears to be the problem; it appears the negative start terminal on the starter is almost a dead short at 0.5 ohms. Is there a way to fix this or are we talking a new starter? Also, where can I get one?
Perhaps I should take this opportunity to convert to 12 volts; are there conversion kits out there?

I responded to too old a post, so I am adding new info.
My 430 was stored and not started all winter. Come spring, I charged the battery, and tried to start her. Just the click happened no cranking. I cleaned all contacts on the battery, ground and starter swich on the starter body. Still nothing. I then bypassed the start switch, and contacted the battery negative wire directly to the start terminal on the starter. Still the same ckick; the battery is good, and does not drop under load, as I monitored it with a voltmeter. The most telling was the 0.5 ohms on this terminal.

Thanks all for any help, including where I might get a 6 volt starter, if necessary.

Ed, the DC ohms of a starter is typically fairly low and a lesser quality meter may not give an accurate reading in that range, dont forget they can draw several hundred amps which equates to very low resistances at such low (6 or 12) volts. Typical starter problems may be worn bushings causing the the armature to drag or worn brushes etc assuming the battery and cables n grounds and switch are allllllll okay?? Its good to remove n clean n wire brush n reattach each n every battery n starter n switch n ground cables when you have starter??? problems and I prefer 00 gauge cables on 6 volt systems. With a good starter n cables n grounds and a big heavy battery tractors that were originally 6 votls ought to start okay.

0.5 ohm is too high. A 6V starting circuit should not measure more than 0.01ohm from the battery cable to battery cable through the entire starter motor circuit.

My 430 has had starter lockup problems for years. I don't know how many times I've had to loosen the mounting bolts to free it up. Perhaps this is the problem with your starter. It would act like a dead short.

I will try loosening the starter, and even pulling it off. I noticed this suggestion in the old thread.

when it stops snowing here, I will actually do it.
I will let you know the results.

Thanks for this suggestion. I did not realize this should be so low.
I thought about using one of those 12 volt starter boosters, and I am glad I did not try it, as it would likely melt the jumper connector.

Also, I did not account for the inherent resistance in the meter probe wires, which would indicate higher resistance.

Thanks.

Thanks for these suggestions, you all may have saved me a couple hundred bucks on a new starter.
A bigger and better battery is something that may be in order, since the one I have is maybe limited in power, considering your info.

I used a dremel tool on all contacts; they seem to work best for these kinds of problems.

Thanks again, I will get to it after it stops snowing.

Thanks to all three of you that responded. I believe the problem was caused by a combination of what you all suggested. The last thing I did was loosen the starter from the engine, and put it back. It worked after that.
I will know to expect this in future.

Thanks again for this forum.
