I took off my blower motor and wires about a week ago and didn't pay attention to which of the two wires went to wich plug!!

There are TWO seperate plugs and not ONE keyed plug. The general wasn't thinking on that one! (and neither was I)

You guys know which prong gets the 12v (purple wire) and which get the ground (black wire)

It is a tight squeeze in there....

what about a plug-n-chug.... will reversing the polarity damage that motor or just act to take my cab air and push it to the atmosphere

Don't ya hate stupid s#$^ like that?!

Sorry to hear about the BB episode, hopefully this will go better.

My diagrams show the purple (+) going into a more ROUND connector, and the black (-) lead going into a SQUARE like connector.

This is for a '70, but should be the same. Never seen it in person, but that's how the General drew it up.

This is for an A/C car, I thought you don't have A/C???

One of the perks of buying a car older than me! It WAS an AC car.... been a long time since it's had it I bet.

Purple wire has a "round" rubber cover on it's femal connector.

The other wire has a square cover on it's female connector.

PROBLEM: I have two male prongs sticking out of my blower motor and they are about 3 inches apart...

I will just plug it up and maybe my luck will turn around for me???? If hell freezes over you will know my first attempt worked out!!

If I recall properly, the round one is made of a soft plastic and it snaps over a round button on the + terminal on the motor. The square one goes on a ground tab on the motor housing.

 

[Coppertop]

How 'bout this...

Take an ohm meter, the terminal that reads continuity between it and the acutal motor casing (ground)-- is the negative one.

 

[JWagner]

Coppertop: Would not the "hot" lead have good (but not perfect) continuity to the housing and its ground?
Maybe getting a reading from each terminal to the housing would allow one to conclude that the lower resistance value would be the ground and the higher would be the path through the motor windings?

CopperTop. i'll check into that. I would think the "ground" of the motor is not connected tothe chassis of the motor. It is a brush triggered coil. Much like a remote control car's motor. Each terminal is independeant of the chassis. So you can hook up the thing back-wards and then the back EMF....

I'm just gonna hook it up and see how the hamster cage spins..... if that doesn't work I may just put a hamster in there and feed it every so often
