Does any one know of a simple inline overvoltage control that can be installed in the alternator power lead.  I have an internal regulator, alternator and the overvoltage units at ACS are part of a voltage regulator and quite pricey too.  JohnD

Thanks Al, I was looking for this, and couldn't find it to save my life. 

 

BTW, if this is the same as the module I used on my RV-8, it works by tripping a breaker when the over voltage occurs.  Normally, the breaker is supplying field current to an alternator, which almost always means an external regulator.  If you don't have a low current way to break the field current, and need to break the high current line, then you have to used this OV module to trip a breaker that's holding in a main contactor for your high current "B" lead.  If any of that was confusing, Ed can explain it :-)

 

Cheers,

Rusty
