could it be the fusible link beetween the
> (A+) terminal of the voltage regulator
> and the starter relay?
There is a fuse-link between the Battery side of the starter relay and the Alternator. Use a voltmeter or 12v test light and look for 12v at the BAT terminal of the alternator. No voltage indicates that the alternator fuse link is probably burned out. (A continuity test will tell if the link is open/closed) This same link also connects the A terminal of the regulator with the Battery side of the starter-relay(yellow w/white dot wire)
Hope this helps.......
