Hello Everyone,
I bought a used Pentair Mastertemp 400 a little over a year ago. It sat on my pool pad all year until I was able to run a gas line to it. Last week I made all final connections and powered the unit on ready to start the swim season. Unfortunately the unit did not power on. The firemans fuse was blown. I replaced it and it immediately blew again. After taking off all the panels and inspecting all wires I found no damage and no loose connections. I did however find something that I can't figure out. The red neutral wire where the main power connection is made is HOT! (backfeeding) The system is set up for 120v with the correct plug in place. Black wire is hot, Red wire is hot, green ground wire is not.
I have a friend who is a pool tech and he said it was a bad transformer. I replaced that yesterday with no change. Anybody out there ever seen this before? I imagine there is a wire that is plugged into the wrong spot somewhere but I can't find it. Any help you might have would be greatly appreciated.
