Another thought: Shorted isolation diodes can result in this kind of behavior. When they short, they create "sneak" paths that weren't there before. Then all kind of strange things can happen. A diode should measure high resistance in one direction and low resistance in the other. When shorted they measure low resistance in both directions. -Joe Kuchan - > > >-- the next one.
