[QUOTE="Rayo, post: 7664182, member: 629554"] I had something similiar happen when my Alternator went out in my 98 F150.. My "Gas Light" and "Oil Light" both came on at the same time...Then I went to turn the Headlights on, and there wasn't enough power to run them..I also had the Heater on.. I quickly turned the Heater off, my Headlights, and my Head Unit.. If you have any sort of mechanical ability...I can tell you what I did to fix the issue.. The first thing I would if I was you..Is put a DMM(Digital Multi-Meter) on your Battery, and test your voltage with the truck running...It should be 14-14.8 Volts.. If that checks out normal..You're Alternator is probably fine, and it's something else wrong.. I pulled the Alternator on my truck..Removed the Voltage Regulator..Checked the Brushes on the Voltage Regulator...They didn't look terrible, but they didn't look new either.. Then I took a look at the Commutator Rings inside the Alternator..These are rings inside the Alternator that are porcelain covered with Copper... When the commutator rings go bad..You can see the White from the porcelain..Basically the Alternators brushes eventually wear out the commutator rings...At that point you either have to get a New Alternator or have it rebuilt by someone.. When your brushes on your Alternator go bad..Really wore out..You can usually just get a new Voltage Regulator with the new brushes on it already..It's pretty easy to swap the Voltage Regulator out..You just need a Torx Security Bit for your Screwdriver.. You can also just replace the Alternator Brushes...Napa has them in stock..I can get you the part number if you need it.. I decided to just replace my Alternator..It was the original Alternator, and from the looks of the Commutator Rings...I couldn't just get some new brushes, and be done with it... Had the Commutator Rings been good...I would have just replaced the Brushes, and saved myself $50.. It didn't make sense to get a 13 year old Alternator rebuilt..When I could just buy a Brand New one with a Warranty for $95..Versus..Getting it rebuilt for $50..Without a good warranty.. Hope that helps.. [IMG]//content.invisioncic.com/y282845/emoticons/thumbsupwink.gif.129404938effda6ad9cca39e7f4b58a3.gif[/IMG] [/QUOTE]
