Late 60’s power window motor repair

[sprice]

I have this motor that I took apart and cleaned all the parts. Didn’t work at all. Not sure if it was the hardened grease or electrical. Anyway put it back together snd it spins great in one direction. This metal points-like strip was at an angle not touching the contact. It works in the one direction like this. I tried adjusting, not knowing where it is supposed to be however if it is in contact, no action. The gap is about .40. I read this is a bimetal strip for overload protection. What position is it supposed to be or am I missing something? I know i can get replacements that will fit but these are in my hand if it’s not much to fix, I would rather do that. Thanks.

Should spin in both directions?

Just guessing here, but if it is indeed a bimetallic strip, the points should be touching (no gap) all the time so that current can flow under normal circumstances. If the motor overloads (like maybe a kid's head stuck in the window by his mean older brother) the strip gets hot and "opens" the circuit to prevent the murder (fratricide!). Otherwise, there's no other need for a strip and points. Again, guessing.

I wonder what @Big_John has to say about this.

A funny thing....when I first looked at your pix, I was confused by all the yellow wire, looping here and there. Oh....it's your markings highlighting the points!

That a Prestolite motor? I might have the repair book. Need a Prestolite number if it is.

I'd need to see what that is feeding on the other side to really tell what's what.

If I were to take a guess, the yellow wire goes to that contact/bimetallic strip and then to the other brush. That's the only way it makes sense based on the picture.

So if that's so, the contact needs to be closed to function.

But, the picture also looks like the yellow wire is shorted against the brush shunt wire, so nothing would work if that is so.

Is this the number you are needing?

I just solder the points closed when I come across one of those bimetallic circuit breakers that's failed in the open position.

Those are for cars that have kids in them that will play around and hold the switch in one position for minutes to see what happens.

That llooks like a mopar number, think I have on one a barracuda motor I will get a shot of.
