Finally figured it out.....Took the Alternator to the shop again along with the Holley harness ........ he used the Holley harness added 12 volt power to the harness......put the alternator to the test and Bingo 15 volts...Again he asked me how I had it wired up......told him keyed 12 volt power right into the harness...With the key on the connection check 12 volts into the harness.....So...He tells to check everything in the failed condition......Checked again (12 Volts) and started the car.....No charging so I check the voltage at the harness connection and it said "0" volts......ended up the wire I tied into had 12 volts power till the engine started then it dropped power......Don't know how or why......I changed to a different keyed power source and started the car and Bingo....15 volts.....everything is working perfectly now.......Sheesh !!!!!!!.... Drove the car about 50 miles and temp stayed at 185 and alternator charged perfectly......This Car stuff is hard sometimes........LOL
