question: does the thickness of the replacement wiring matter?
there was no insulation left by the time i got the original wiring harness open. so i could not tell. I used 18 gauge wire for the bigger 2 wires and the rest were 20 gauge. I have read somewhere that in this specific application the wire thickness could have an effect, and that 2 or three wires should be 22 gauge. not sure about this, and not sure which ones....

This thing was working great before rewiring. this has to be a wiring issue....


any help is highly appreciated.......
