Hey, TT, maybe Enfield could get you to write a electrical trouble shooting manual, thanks for the tip, I hate electrical problems. Don
Electrics are just another form of logic puzzle. Just start at one end of a circuit and follow through until you complete it. That's when the lamp lights!
The worst thing that one can do is to "dive" into the middle of a fault and start tearing things apart. At this stage, you can be fairly certain that you now have more than one fault!
