Upgrading my alternator on my 6.2 diesel.

I noticed the gauge was acting weird and decided to have the alternator tested. Yep it was bad. Got to looking and someone had put on a 37 amp unit off of an astro van. Not sure what they are supposed to have but I thought it was around a 66 amp unit. I didn't want to put a new 37 amp alt. back on so I upgraded and bought a 94 amp. I just felt that it would be better for charging both batteries and if I decide to upgrade the radio or put in new updated relay harnesses for the PW and headlights that it would be a better fit.

Picked the new one up a little bit ago and getting ready to put it on and see how it does. Ready to start driving this truck to see how good it's going to be. I just bought a reman from Napa since I didn't really have the time to wait to have one shippped in. We just looked through a few of them until we found one that matched up and the clock position was in the right location. This is not what it called for by application.
