I'm needing some tech help. I put a newer style, from the junk yard alternator on a fox body 5.0 for a guy. The reason for adding this is because he had upgraded to an aluminum radiator and dual electric fans. I upgraded all the wiring as needed for the new alternator with 4ga wire and a 140 amp breaker. He drove the car abour 25 miles round trip, got back home, shut off the car and it will not start back, he told me the amp guage would barely stay just above red. The paperwork with the fans stated they are 20 amp each. He has the fans wired on a relay and they run all the time. Any suggestions??
