Well, finally got a chance to take the alternator out. The unit on the CAV is a Delco unit with an internal regulator, with special bracketry to fir it to the 302. It also does not have the fan installed; perhaps to clear the bracket and in anticipation of little usage. I'm sure this is the cause of the failure. Interestingly, there is a protective cap with mesh sides in the back, to protect against debris since it sits at the bottom of the motor. I brought the unit to Sailon Electric in Syosset (one of the last remaining motor/electrical specialty shops in Long Island) and settled on a 70 amp replacement unit, smaller, internally regulated, and with an internal fan. Works like a dream, should last the life of the motor.

Cheers!
