I think your on the right track Bluebird. I did notice that the pink wire was a resistor wire that says on it "Do not cut". I'll try hooking up the yellow wire but not sure it will help. The pink wire isn't hot on start up. It gets hot while runs and gets hotter in my hand till I have to shut it down. Yes, I did run my hei off of just the pink and black wire with no issue's. But to be honest, I never felt the wire during that time so not sure if it was getting hot or not. I assume is wasn't. Hopefully I hear from Mallory today. Thanks guys. I truly appreciate your input.
