Re: Heater blower ?/problem

It would be good to do one small step at a time to see where things go wrong.

1) With motor reinstalled, see if it will spin with two wires directly to the battery.

2) See if the motor will also spin using the stock grounding wire and one wire to the positive terminal of the battery.

Once it passes those two tests, then we can dig into the stock wiring to see what's going wrong there.
