Alternator question on LS 3.9 V-8 I am about to try to replace my alternator and searched the forum for info and can’t seem to find any, is there any one that has attempted this and is it a big job. Thanks,

I have a 2000 LS 3.9 I had no heat so I checked everything inc. relay, fuses, everything seems fine. My pump in the diagram #21 does not have power, I jumped it and it works, so the pump is good. Would anyone have a wiring diagram of the 2000 LS 3.9, so I could trace everything. Thanks

I'm looking for some help i have a 2000 LS and my cat was gone on one side so what would be the best way to fix this, because the new one's are very expensive. I took off the exaust completely so i'll be able to replace them. Thanks Razzi123
