Electrical question for the brain trust.

I have a 6Vto12V conversion on my street rod, the 12V is too hard on the starter bendix. Is there a way to convert a 6V starter to 12V to lessen the
abuse on the bendix? I am running out of starters TIA. Sam Womer(PA)

A few years ago, I converted my 1950 International Harvester pickup to 12 volts. When the starter burned up, I had the local NAPA store send my starter in to Wilson starters (You can Google them. I think they are now owned by BBB) and they put in new field windings, an armature and new drive. My local NAPA stores have a connection to Wilson. I had specific instructions that this was to be run on a 12 volt system and they rebuilt it and it worked great. It took about a month, but that was pre-virus. Before I get hammered about not using a local generator/alternator/starter rebuilder, my local guy shut his doors and I'm not sure that I have one within an hour of me. I normally rebuild most of my own, but this I wanted done using the correct armature and windings the first time.

just wondering what engine or starter u have now, ford? some people use a small low amp battery and thin cables to lessen the hard engagement. i am not a fan of using a 6 volt starter either too hard on ring gear and bendix. can either find a 12 volt replacement or change that one over , but it will be lots and i dont know if the field mounts are the same. its kinda like pulling a stuck tractor with 6 ft of slack in the chain compared to using a nylon strap. something will break.

had same deal with farmall smta ; a local electrical shop that speciaiizes in starters generators ,etc, converted the 6v starter to 12v for same reason. was not overly expensive.

In 2nd link scroll down thru the blue text links for the pdf on converting 6v starter to 12v, with part numbers used.

The problem with conversions is most people want to leave the heavy cables that were necessary for 6v operation. Then they want to throw a 1000 amp battery in there to fire it up. Exactly opposite of what they need. Volt's isn't the problem, it's the amps that does the work.

Install the smaller automobile cables and a small battery with the appropriate amps and there won't be any problems. Most 12v batteries sold today have twice the amps you need and some are three times as much.

For an M I would just put about an 8 GA wire on it and it will start just fine. I had to do this with Dad's H he wanted it to not slam the gear into the starter so hard. He had some problem with wrapping the smaller wire around his head . Supposed to be a big wire to carry the juice. After I changed the wire and he saw it work he quit talking about it. Still has the 100 amp battery in it yet. Most of the batteries come from the left overs when one goes bad in the semi I change all 4 and use the rest on tractor or other equipment saves buying and uses the old ones up over time.
