If you need a manual for this PM me. Dirt is all over the 1000 issues. We use to cut off the molex connectors and replace with single female slide on connectors. Mark wires and take your time and you will end a lot of weird problems. Power supply is the other problem child but once you know you know. I started logging all my jobs not just these so you knew when it was running correctly the DC voltage and how much AC was being passed. Saved me hours of trouble shooting down the road.
