Charging system issues....
Hey i have a 2002 8g 4 cly... Couple of days ago the ORIGINAL alternator went out and i replaced it with one from advanced auto parts(2005 eclipse 95amp refurb) After install car started up but was still not charging the battery. I bought a new battery and tried it again and still same issue car is just running off of the battery. I was getting brake light and battery light that stays on.
So i removed alternator and had it tested to see if that was the problem.(autozone test in-car not showing any power from alt.) Out of car test show alternator working just fine so i re installed it. Same issue no power from alt.
I double checked the plug and ground on alt and its clean. I also cleaned battery terminals some corrosion but not bad. battery terminal fuse looks good. checked fuses in fuse box and they all look pretty good.
ANY IDEAS ON WTF IS GOING ON HERE ??????? Next step is taking it to a shop, but i would hate to do all that work and they connect one wire and tell me they replaced half the engine and charge me $600. THANKS IN ADVANCE
