I have a friend who is a facilities maintainence mechanic and is trying to fin a wiring diagram for a heat pump. The diagram that was in the outdoor unit is washed clear of print.

He's not much of a internet guy so he asked me to look.

It an Nordyne/Interthem unit C1QA-036U-B and he can't read the number on the other unit, but it has a Feb9404 on it.

Any ideas?
