Regulator Issues?

Post by TonyB »

Hey folks, my alternator isn’t charging my batteries anymore. Looking at my old ARS II regulator there were no LED lights on it. Called Balmar for help and they said the old ARS II was likely dead and I should replace it. They recommended the ARS 5, so I bought and installed that yesterday. No improvement, display doesn’t light up at all. Wish I had done more troubleshooting first.

So digging in yesterday I found with switch off 12.8V (battery voltage) on Red. 0V on Blue and 0V on Brown. So far so good. With switch in on position I get 12.8V red 0V Blue and .5V Brown. Brown should be 12.8V. With switch on. So now I am wondering if there is an oil pressure switch in the Brown (switched) circuit.

This is a Freedom 40/40 with the 3Jh2 TE motor.

Thanks!
