Ok, I have a Plane Power 60 amp alternator. It works fine for a while then, it doesn't. We've run out all of the wiring and checked the belt. We looked at the plug and tugged on the wire. All good. We've done this three or four times. Every time, after we check everything over, it works again for a flight or two then, we get a low voltage warning and sure enough, we're running on the battery (12.3 volts and decreasing). As a last resort, I have purchased a new plug, pins and seals. Today, while removing the old plug, I noticed that the white wire (unused) was in the correct location (#1) but the aircraft red wire was in the center pin location (#2) rather than the #3 position as depicted in the Plane Power drawing. The jumper was installed correctly between #2 and #3. Could this possibly make any difference? Can't see how it could since the red wire is connected to the jumper and would be connected to both pin locations in either case.
