Quick charging question...

I havent touched my vr. I did upgrade to the chrome box ecu though? Does that require a less ohm resistor? I just put in a new regulator and all of a sudden have same problem...
Is there a way to test regulator? anyone... thanks
the VR controls the charging output of the alt to the battery. i use black ,chrome ,orange boxes all with the same ballast. you just said you switched the VR
