My 72 Malibu has an 80's Chevy truck alternator in it (63 amp, internally regulated I guess?) and has been upgraded to an HEI ignition. The alternator's got a 2-wire plug, the red wire runs to the back of the alternator case, the white wire is cut. Is this correct? I just installed a new alternator from Advance Auto Parts, it burned up the regulator in 2 weeks. Any input would be appreciated
