Hey guys my trucks seems to be having some sort of electrical issue and i cant figure out what it is.The trucks gauge reads almost 14 maybe a lil over before this issue arose. Now it'll hold below 12 and slowly fade till its drops off completely and the idiot buzzer goes off. So I have replaced both batteries with red top optimas with 1000 cranking amps and 880 cold cranking amps, checked all the ground connections, and am now wondering what the hell to do. Any help on this issue would be greatly appreciated, thankyou for your time Ken

 

sounds like your alternator bit the big one....

 

Is there a way to clean the alternator or do I have to suck It up and buy a new one

 

Some parts store have testers for alternators. It wouldn't hurt to take it to one and have it tested, it's usually free. If it is failed, they should have one for you.

 

there is such a thing as having an electric motor repair shop rebuild your alternator. If you don't see 14volts with the truck started then in most cases the alternator is not putting out. time for a new one or to rebuild what you have.

 

Remember their PCM regulated but in this case it really sounds like an alternator.
Since it wont let me make it like a chart, the 136 is rated amperage and the 100 is the minimum allowed.

Denso 56028696AA 136 100
Bosch 56028699AA 136 100

 

If you have an original alternator dont turn it in for a core. The Chinese remans SUCK. Fix it yourself for $27- Alternators

If your alternator is good you should have around 14.4V when the grid heaters are off.

Oh and I believe most parts stores will have bearing kits if you need them.

 

Who do I go through so that I can fix it myself?

 

look at the link i posted in the previous post

 

Hate to sound dumb but I have a 2003 and that year isnt specified so am I good to just go ahead and use these replacement pieces on mine or are they not compatible?
