I have a 300 amp Excessive Amperage alt with an external voltage regulator. This alt puts out really good power, but for some reason my headlights pulsate (all lights, even interior). I've had the external voltage regulator replaced and it still does it. The regulator is wired up with 8 gauge and a 30 amp relay that turns on with ignition. Do you have any suggestions? What causes this? I just cannot pinpoint wtf the problem is besides the alt being messed up or off a little. Doesn't matter what voltage I'm charging, it does it.

 
Mike said try 4 gauge wire. He also said it happens with external regs if the power wire isn't large enough
There's only a 15 amp rated draw on my regulator, how could that be? I mean 8 gauge should be plenty. And I did send him a message on caco. I guess I can try it.

My voltage drop is worse than just lights dimming, it actually shuts off my head unit and my amp goes into protect. At night I can't even turn up my stereo or I can't see from my lights almost turning off..lol
