Better than OEM!!!
by Adam from Bowling Green, Kentucky on December 17, 2012
The yellow wires can be installed in any order... makes for super easy installation. My motor charges great now. Idle is about 13 volts, driving down the lake it's 14.5 of higher... charges so well i am thinking of installing an isolator to charge my trolling motor battery with it between fishing spots.

It Works!

After 8 years of being told that my boat didn't have a charging system, I find it just had a bad rectifier. Got this one and it charges.
