Check the coupling
Check the coupling! It may not be an electrical problem at all.
One problem that is quite often over looked with the alternator is the drive coupling. Quick check. Leave all switches off. Take front cowl off. Reach into the fan area of the alternator and see if you can turn it. If it can turn, the rubber coupling with a gear attached to it has to be replaced. This is a quick check before you start spending a lot of time and money chasing an electrical ghost.
