Thanks you for posting that information. I bought the 300-884 Relays a couple of months ago and they actually arrived yesterday. I bought the rectifiers and some diodes. I will use your list to collect the rest.

I have been thinking about why there would be so much trouble with these alternator lights if both regulators are set to the same voltage, either 27.7 or 28.8 volts. One possible area for this is since these are not paralleled in real time by the regulators, there is potential voltage drop from the rear to the front, thereby the incoming voltage from the rear would then be less that from the front. Just spitballing.
