96-98 Vortec Alternator Upgrade AD244

[kennythewelder]

Yes a larger alt is a good idea, but along with that, the big 3 upgrade is a grate upgrade. The alt out put wire that charges the battery, is very small at best. By adding a large wires to the system, this gives a larger path for electricity to flow and charge the battery. You also add the same size wires for the ground side too.

Would this be the one?

Looks right, 145 amps. But read those reviews, quite a few ppl said they don’t last long, buy a better brand.

I think mine came from the factory with the large alternator. I added the second battery as the tray was there.

Does anyone have a part number of one they got? I found one on summit that looks about right, but just wanted to be sure.

ok guys. I just read all 18 pages of that and damn. i have a 98c1500 5.0 vortec. i have already done dual batteries and seperated the passenger battery ground to the driver side to the 2nd battery and have 2 wires connecting the 2 batteries together. pg14 bottledz28 and page 16 killian posted about the coolant hose in the way. I have that issue as well as the AC line on top of the alternator doesn't have enough clearance and presses into the alternator. to get the new alternator in I had to loosen up the ac compressor bolts. the ac compressor is floating over a quarter of an inch and the line is touching the alternator. the alternator I purchased was a duralast 140a from autozone. it is bigger than the oem style one but looks similar size housing to all the upgraded variations I have seen here. any thoughts?

please be nice I'm new to working on my truck and to forums searching.

The solution is simple: GENTLY bend the lines out of the way until it all clears. I've done this conversion twice and never had an issue making it all fit. I can post pictures, if you need them.

 

[DRFOX]

wow. I didn't think they would bend that easy. thank you so much.
