Can these starters run off 12v? I assume the box where 120v plugs in is a transformer?

@hebert4230 these are only 120v, you can get 12 volt starters though

Mine had the same symptom. There is a thermal overload device in the feild windings. I removed it, jumpered the device, & it had been fine since...... $150 saved. Burned windings in the armature or field windings woud be unmistakably "black" Tecumseh must have been laughing at all the replacements they sold over the years.

@hiwattmikey could u make a vid on that or send me some pics please?

Really enjoy your videos. I do have a comment on this starter. I just repaired mine with the same symptoms. Try this. Pull the armature out, lightly sand the commutator with fine sand paper, clean the slots with an exacto knife, blow it out and reassemble. Then run the started continuously for 45 sec. to a minute to reseat the brushes. I think the brushes not seating correctly is the real issue here. Worked for me. By the way, a slight burnt smell is common in electric motors.

i have already tried that. thanks anyway.

the burnt smell is a bit more than normal.

i keep the motors just to pull the copper windings off for scrap metal

Hi Donyboy. Thanks for your useful and easy-to-follow videos. Like the Surfintime's note below, I have taken apart a Tecumseh electric starter motor (needlessly, as it turns out), and I don't know how to reinstall the rotor and brushes. There is a white plastic plate holding the brushes, wih no removable holders. Is there a video in your questions and answers, or could you pleaase post one showing how to assemble the starter motor? Thanks very much.

@donyboy73

Do you have a video on how to re-assemble the starter? I can't figure out how to hold the four springs and brushes in place.

Thanks.

do you what kind of ring gears would the snowblower starter engage with? or the pressure angle? could someone give me that information ?

[rockalittle00]

thanks very interesting.

I got your message asking for a video or pics of the "jumping" of the thermal device that I mentioned. I did this a year ago. & did not do that. Its still working by the way.This took some surgery on the field windings. After getting it all apart, within some sleeving was a metal thermal device(about 1/2" long that I removed & jumped by soldering across where it was. Be aware by doing this, prolonged attempts to start will definately burn it up & be a safety risk. do so at your own risk!
