17 volts is obscenely high and tells me you have no functioning alternator regulation. If you continue to run this way it's going to damage something. Maybe it already has, particularly your Channel Islands overheated coil. Have you replaced that coil? You should.

I did just test the exciter wire its the only one with a square connector and a coil in the wire, the voltage increased in this wire as well.
Strike two on alternator regulation. Based on what I'm reading in this thread I recommend replacing the alternator outright.
