Pulsating headlights?
I've noticed that my headlights pulsate between 100% brightness and about 90% brightness when the engine is running. I plan to check voltage today but I want to find an analog voltmeter to get a better idea of what the charging system is doing.
Has anyone else experienced this?

yep, mine did it. Had to replace altenator. Took me for shots at oreillys to get a good one, if I hadn't needed it right away I woulda have ordered good one. Bit don't wait to long the bad alternator could hurt your ficm.
