Review on πŸ’‘ 57294 Powermaster Alternator by Matt Weber

Revainrating 5 out of 5

All amps! Great unit!

Installed on a 1970 Chevelle with 383 fuel system, Holley Sniper and electric fans. The original alternator was tiny at 37A and the open circuit voltage dropped to 11.6V. I installed this Powermaster and now I have a stable open circuit voltage of 14.3 with the fans and lights on. Highly recommended!

Pros
  • Confident
Cons
