Electrical issue...alternator?
I recently had a racetronix fuel pump installed with the upgrade wiring harness. It pulls power directly from the alternator (74000 miles) and for some reason, my lighting has been acting up a bit. One odd thing is that when I hit the brakes, the lights will dim on my head unit. Same will happen when I use the turn signals and will dim in sequence with the signal. The harness grounds to the passenger side ground location btw. The volts (on the guage) are always above 13 and look to be around 14 when running during any kind of driving. The car has the factory alternator and 3 month old red top optima battery. Car starts right up and no other issues. My guess may be that the stock alternator doesn't have enough to sustain all the stuff I have electrically. However, all my lights on the exterior besides the headlights and fogs are LEDs (all of them) so I should be drawing less power to run them. Only additional things that I have running are my small amp and 2 subs which are really not big at all. Any ideas?
