Update: Traced alternator output terminal (B+) back to battery - the previously posted electrical diagram is wrong as it does pass through the X12/3 connector. Detached both ends and measured resistance of about 10 M-ohms so it's pretty much toast. During the process, found windshield drainage duct (#53 in attached) totally plugged with debris - it must have been water tight as it was completely composted black! So, water was pooling around these cables every time it rained for quite some time now.

I just soldered some ring terminals on an 8-ft length of 8AWG stranded cable - we'll see how that works in it's place.
