Belt slipping?

[yodaddy4200]

today on my way home from a quick trip my trucks headlights and heater acted like they were gonna die? My headlights went dim for a short sec and my heater did the same? My first thought was the alternator was acting up. If my serp belt was slipping would that cause this? my headlights flicker sometimes could this be related? ill have my alt checked tomorrow i guess... i dont think my belt is loose my buddy suggested that. Thanks!

I was going to say get the alternator checked out. Sounds like one of your brushes is almost gone. But this is just speculation. Has there been any major or electrical work done to the vehicle in the past 3 years? I would also check the condition of the battery cables to see if there is any corrosion underneath the red and black boots. Thats where the cables terminate.Also inspect the side terminal bolts for corrosion and stripped thread. You will need to pry them out with a flat blade screwdriver in order to check the terminals.

there was some electrical work done. Six days after i bought this truck i got and check engine light (P1680) the stealership didnt want to fix for free but i said F#CK that i dont want this pos then.. they fixed my clutch fan and reflashed my pcm... no trouble since.. they wanted $900 to fix i raised hell and they did it for free..

Had alt and batt checked both good. havent had time to actually take the box of the batt and check it out. wifes leaving for work and my 17m old doesnt watch herselflol ill check it when she takes a nap or something! i was kinda hoping my alt was going out so i had an excuse to upgrade and do the BIG 3 before i do my stereo!! (probably jinxed myself lol)
