Dimming lights Options

[jbiggs97]

I have had this issue for many months and recently have decided to try and solve it. I know that when stopped with my, lights/ac/defrost/radio/brake pedal pushed the volt reading off my turbo timing drops considerably hence the dimming of the lights. Sometimes the volts will slowly rise back up to 13.5 and sometime they stay down as low as 12.2. At idle I tested the the terminals with a volt meter and it reads 14.3v. According to what I have been reading this tells me the altenator is working fine....could the regulator in the altenator be bad......any thoughts on this. I am getting ready to start doing some other mods and thought I would try and get this out of the way.

I have already tried a grounding kit and that didn't help.

Mine goes as low as 12.5 sometimes to. But I am surprised my stuff works at all sometimes with all the splices and wiring stuff we have done to the car. To get a accurate reading of the alt. you need to take it off and have one of the parts stores test it. I am not sure it testing while on the car is as accurate. It will put out different volts/amps under a load and not. My 2cents is to take it off and then have them test it then you will know for sure.
