My last post a while back talked about me cleaning the regulator's points with a dollar bill and then the amp gauge read complete discharge. I had the generator overhauled and picked up a USA made regulator just in case I needed it. Got up to the farm yesterday and put on the generator, polarized it and ran the tractor. Still no charge. So I grounded the field terminal and it pegged the needle on full charge. So I replaced the regulator and now it worked fine. No more hard vibrating back and forth and after about 3 minutes of running it, the gauge settled out just slightly on the charge side. Only thing I had planned on doing was to push the cutout relay shut on the old regulator and see if it charged, just forgot to do that. Anyway, with the new regulator and a repaired generator, everything is back to normal. Next time I guess I will have to use a $100 bill instead of a $1 to clean the points. Thanks guys on here for the help.

You were very lucky that a "new" regulator worked. Just toooo many of them are junk these days. People just don,t understand how they work cause all of the new stuff is a little Black Box of a device. Good for you.

Thanks for the update. About 1/2 of the "repairs" get feedback. Jim

Take a close look at the field contacts for pitting
before scrapping your old regulator.
Use a strong hand lens to inspect the contacts. You might use some emery cloth to clean the points &
then use crocus cloth to final polish them.
Usually is what causes trouble in the reg. Use a clean cloth--such as a handkerchief--to pull
through the contacts for final cleaning.

Might need it sometime for a back-up unit.

Today's Featured Article - Allis Chalmers ED40 - by Anthony West. Allis Chalmers as a tractor manufacturer in its own riht is but a memory. However the number of AC tractors still in existence today as either restored or unrestored examples is a testament to the quality of their products. This in itself is always apparent here in the U.K when attempting a purchase, as no matter what the model or condition the price will always be strong. ... [Read Article]
