Ground wire location on 1996 blazer
Hey guys, have a little problem with my 1996 blazer. The lights "pulse", so to say. I checked the alternator, and battery. Battery wound up reading weak, so i replaced it. Well, still the same thing is happening. Now i am thinking it has to do with a bad ground connection. Maybe i am wrong. Thanks for any help.

Pretty common problem, usually it means the alternator and or voltage regulator is on its way out. Some of the auto parts stores will check it for free, but keep in mind you get what you pay for, and their testers are not 100% reliable.

Who tested the alternator? Was it a shop or a parts store?
The regulator is controlled by the PCM on your vehicle. Although it's rare, it's also possible there's a problem with the PCM or wiring. The voltage regulator is inside the alternator so it requires disassembling the alternator and sometimes requires desoldering the old one and soldering the new one in. The option is replace the alternator, (it comes with the regulator) IF that's the problem. Best to have a qualified shop check it out.

Yeah those auto store testers will a altenator or battery is good even if barely passes the test.Just in case it is a ground trace your ground wire from your battery to where it bolts on the frame and check that connection for loose connections or corrosion

Just curious, does it do this when your heat is on, When I turn my heat on, or blower motor for that matter, on anything but low, my interior lights pulse, if its on high, my headlights do for about 5 seconds.
I am just too lazy to clean the ground for the blower motor on the firewall. Just an option.
