Thanks Timmy2. I cleaned each pin with a small emery board yesterday before all the testing that was made. All pins are very bright.
Anyone know if the wire placement in the plug as shown in the photo is correct:
The wire pattern is:
Black-upper left for power
White/yellow upper right for medium speed
Green/white-lower left for low speed
White-lower right for high speed
It appears to me that the back of the plug which snaps off has been opened in the past from the pry marks on each side of it. Just wondering if the pins were removed at one time and then replaced properly. Checking everything that I can for accuracy.
Thanks everyone for the assistance. Much appreciated. If I had any hair I would tear it out on this one.
