So I've noticed this little issue for a couple weeks now. My headlights "flicker" almost, on certain days. Especially under heavy electrical load at a stop. (Rear defroster, ac condenser on) The flicker or dimming happens when I engage a turn signal, or anything of the sort as well as just normal driving. The other night while in a drive-through, the radio even turned off for a second due to lost power. Could this be my alt. getting ready to crap the bed? Is there a way to test it without ripping it out? Anyone ever had this problem?
