I've got the opposite problem of the Aux Motor being on non-stop once I connect the battery. Even unplugged the wire going to the heat lever and it keeps running. Is this an indicator of a malfunctioning relay?

Must be shorted to ground somewhere after the lever.

Same problem as well, I noticed however; if I put a little pressure on the lever to the left (not fwd or backwards) (sideways). Fan motor stopped. May be worn out spacer?....I have to take it out this weekend and take a look. See if it can just be cleaned. QM |

IIRC correctly the relay is the same for the fuel pump so......??? Car wasn't running. Been a long time but I remember this circuit well as the trace on the board (regulator plate) was the problem I encountered. What a tracing testing nightmare that was. Probably why I remember it. Glad you got it working by just pulling the relay. |
