I left all my stock wiring on there, if i had a little bit more time or another car to get around in i would of switched everything out. Try the truck alternator man, mines working like a charm right now and i bought mine used at the salvage yard for $65 with no core charge and it has a 1 year warranty. Make sure its out of a 99-03 Truck/Suv and its the 145 amp. Talk to member anthony williams, he said he can get hook ups with a better 175 amp alternator.

Look at the AD244 compared to one of our stockers. Bolts right in place. There are other places that carry them I just threw that one out there.

Sounds like something is wrong.. It should have a 4 pin, if you go back to the first page of the thread you can see where sjsingle1 posted pics, in one of those he left the connector attached, pay close attention to exactly which wire he left long and connect to that one, my connector came with 4 long wires but I had my original connector to compare to, get one of those connectors then cut the single wire you had going to the 2 pin connector on your car and connect it to that one wire of the 4 pin that is shown in sjsingle1's picture. Should be good to go from there. Its the L terminal that you want the wire to be connected to, you will see which pin that is if you look at the truck alternator, the pins are labeled on the black plastic part of the connector plug on the alternator, the pins are not labeled on the wired side of the connector though, just on the alt.

The GM LS-Series engine equipped vehicles from like 97-03 should have the 4 pin connector. Yours has to have that. Look up anthony Williams, he was a big help to me and he said he can get you a 175 AMP alternator for like $170 or something like that.

Just to update you guys, My friend let me borrow his Radar detector this last weekend. The radar used to be mine but I sold it to him, but Its a nice one that shows which direction your driving and shows your cars Voltage. On the road going 45 MPH, i had the heater on, the radar plugged in and my stereo at full blast and the radar was reading a 13.7V's. I turned off my heater and the volts jumped to 14.3 then 14.2 then it stayed steady at 14.1 Volts. when i turned my heater back on it stayed right at 14 and dropped to 13.9 lowest. This alternator is working so good, im glad i did the swap!

Swap went good, had to bend the ps line a little more than I wanted too but its in. Now I have a horrible pulley squeek at idle; well not sure its a pulley but its definitely something on the front of my engine. Sounds like its coming from the waterpump or somewhere in that area. Weird it happened after I changed the alternators. Ill mess with it friday. If its not one thing its another with this car.....

Well when I pieced this car together after the wreck I very well coulda had the return line turned higher than it normally was. I mean its not like the line is kinked shut now, but it is kinked a little. No worse than the pics the guy earlier in this thread posted.

Ok so im pretty sure my alternator is shot, Its not recharging my battery and a test is showing that its got bad Diodes. I have been told that some guys have installed a higher Out put Alternator in their LS1 F-bodies that came off of 99-03 GM Heavy duty trucks/Suvs. I picked up a 145 AMP Alternator Out of an '03 Suburban today that has the 4 Pin connector. I know that pretty much in order to make it work, i have to just simply get rid of the back bracket and bolt that everyone hates.
My question is, Can somebody that has done this mod please help me out with a Step by step? I have never changed an Alternator on an f-body LS1 before. I might be in for a ride here, but i need to get this fixed, this car is my daily driver, and need it fixed and running before next week for work. Any advice, input or help would be appreciated! Thanks, George
