Works just like it should!
by Armand from Phoenix, Arizona on November 22, 2017
A voltage regulator is either working or not. If you need an exact oem replacement for a 1977 302 this one is it!

Prestolite voltage regulator
by Mike from Leonard, Michigan on July 09, 2017
This product was a direct fit, even to the unusual wire terminations that matched the ones on the boat. Works perfect regulates to 14.2volts. Thanks.
