BEEKAY Posted January 24, 2015 Report Share Posted January 24, 2015 Your setup sounds very similar to mine give or take a few things. Is it just your interior lights? My voltage drop is very very minimal while driving but my interior lights still dim a little. They seem to be very sensitive to any sort of voltage drop. My headlights on the other hand don't dim at all. I believe it's just how sensitive the interior lights are. Link to comment Share on other sites More sharing options...
99blazer Posted January 24, 2015 Author Report Share Posted January 24, 2015 Headlights don't dim just the interiors. And it kinda weird. like playing decaf and rap my voltage will maybe get down to 13.8 to 13.6 but when I play metal it will drop down to 13.4. but other than that its just my interior lights. 08 Ford F150 Link to comment Share on other sites More sharing options...

99blazer Posted January 24, 2015 Author Report Share Posted January 24, 2015 im wondering if this is just a vehicle thing because I ran the same electrical in my blazer and never had any dimming and hardly any voltage drop. and I today watching the voltage close after getting warmed up my alt is only charging at 14.1 08 Ford F150 Link to comment Share on other sites More sharing options...
