Re: [FWDLK] Polarity of fan motor

Tom,

 

I assume your 55 is still 6 volts. Are you sure the fan motor you bought is not a 12 volt 56 motor? A lot of eBay sellers do not know the differences for 55 and 56 Dodge.

 

On a 50 year old electrical motor, the internal lubrication may have dried up, causing a slower rpm.

 

The ground wire should be shorter, with a ring terminal on the end. The power wire should be longer, with a connector on the end.

I replaced the heater fan motor with one I bought from an Ebay auction.  I can not determine which wire is ground and which is battery but I hooked it up and it runs.  Is this motor polarity sensitive or does it matter?  Did not seem to be getting much air out of the dash area, which might be telling me the answer,  but have nothing to compare to since the original heater fan was in-op when I bought the car.
