You should be able to get a 95 amp at Autozone or O'reilly's. Why do you need one over 120 amps?

120 amps is not enough? First can you list what you're running in this truck to determine how much you actually need. Also, remember you'll never get full capacity at idle and you should definitely get an overdrive pulley for it.

Ok. Well I have good news for you. You don't need a massive aftermarket alternator. E-Fans so not draw that much current. If the fan is putting you into a deficit of electrons, then your alternator you have now is just toast. A stock alternator will keep up just fine if it isn't broken. What is indicating to you that it isn't keeping up?

10 amps is nothing. You're alternator is probably shot. When u turn the key to ON before starting the truck, does the battery light come on and does the air bag light come on for a few seconds too.?

Well then there's your problem. Fuse #15. 7.5 amp. Remove and replace. If that fuse is blown:

- Battery light will not come on
- Airbag light will not coming on
- Alternator will not get field current to begin generating power.
