I think I've got it mostly sorted, at the moment, but I've bookmarked your site just in case! Though I admit to being a cheap bastrich, and wanting to save the money by doing it myself. ;) If it turns

Re: OT-how to test and repair DC brushed motors.
Not where I grew up. We had another phrase for that, and I'm too inhibited to use it anymore. I guess we could call it red-neck engineering. Sort of thing farmers do to get critical equipment to

Yep. PM brushed motor. Ohm meter is still useful for continuity checks through the brushes, brush holders, wire from them to the connectors, etc. Dad taught me how to use an ohm meter back when most

I'm pretty sure that is a permanent magnet motor, so no field winding. Jon

Re: OT-how to test and repair DC brushed motors.
Hello Bill; Mr. Ohmmeter would be my friend in this application. Check the field windings to see if they are good, not shorted. Check the armature for shorts and continuity. I am sure that there is a

Yep. That's what we call "micky-mousing" something. I grew up not too far from Disneyland! Dad and Grandpa were great at it! William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by:Good judgement

Yep. But. That particular motor looks a lot lighter duty than these.? American Surplus & Salvage has a window motor without the gear box for $12.50. Long worm-type screw on it. Might buy one of them

Re: OT-how to test and repair DC brushed motors.
It does. Only most of those things are rated about 30 watts at 12 volts. This thing supposedly needs a 20amp circuit to run it. So far as I can see, it only runs one motor at a time. My Ohm's Law

Re: OT-how to test and repair DC brushed motors.
Unless I want to completely redesign it, I need the right-angle gear box. I'm not qualified for that! I could probably put a different gear box on it, but none of the ones I've found are near the

They don't have the brushes I need, nor do they have anything I can cut down to fit. Brushes are 5/16" square, approximately 5/8" long carbon block, and approximately 3/4" spring & braid. Looks like
