On my 1996 chev k1500 my alternator is giving me some issues.
It sometimes won’t charge above 12.5 volts and most of the time will only see 13.9 volts. Sometimes I get fluctuating lights. Generally my battery will not stay fully charged I have been keeping a charger on it here and there to help keep things going.
I don’t believe it’s the battery because it never dies it just won’t fully charge off the alternator. Although It’s about 5 years old so it probably wouldn’t hurt for a new one but I believe the alternator will be first
The alternator that is on it is a Delphi 105 amp alternator I put it on roughly 60000 miles ago and about 11 years ago.
My truck has electric fans and I believe they contributed to its funky behavior. I did a lot of reading and saw that many people have upgraded to a 145 amp from a early 2000s truck which should be mostly plug and play.
So here’s the whole reason for this post. On my 2011 Silverado if I understand correctly is the same style of alternator just with 160 amp rating. Comparing the two the pulleys look to be the same size and it looks like it should fit into my 96 and have all the cables and plugs reach fine with a little modding of the heater line on my 96.
The only difference I see is that my 96 has a 4 wire plug with 1 wire coming out and my 2011 has a 2 wire plug with 2 wires. If I’m not mistaking I believe they can be adapted to work?
I forgot to measure the mounting spacing but eyeballing them they look the same.
I have already done the big 3 upgrade on my 96 with 2 gauge wire. The truck has a stock stereo system and is the wt trim so the biggest draw on it will be the fans.
Is there someone that knows more than I do that knows if this will work or not? I don’t need 160 amps per say but the alternators cost the same so if I’m gonna do it and it will work I may as well go bigger…
