I like the lower profile voltage regulator I had on before, but this one works as it should. My battery is being charged and my electricals are all working.

 johnwilsonp Posted:

the regulator is good but not the plug style I needed. I had to swap one with an old regulator

 stewball62 Posted:

Works great! Just what the charging system needed, and pretty inexpensive!

 ramblers Posted:

Drop in replacment. Heavier then the stock wire. Plug fits in the primary with no leaks!

 83fxwg Posted:

perfect fit

 jasonsch Posted:

It works perfectly and is well made. The crimp on eyelet that came with it was pretty light, so I used a more heavy duty one and soldered it on. My Harley charges right at 14.3 volts now. Thanks J&P Cycles! Shovelheads forever!
