So the large cable connected to the alternator is always alternator output/battery positive. Alternators ground out through the body of the part itself as its bolted directly to the block or other metal brackets, and the block itself is grounded to the chassis, which is grounded to the negative on the battery.I had a good day and a shit day. The good news is the new alternator drive belt is on. It's the brand Endurotec. It's a generic piece of shit off e-bay, made in Korea. The grooves are so shallow.
And now for the shit part. As I was tightening the alternator adjust pulley, the spanner made contact with the alternator output and blew the battery fuse. I didn't know it was the output, it looks like a ground cable. The cap that sat over it protecting it was a shit design and ripped off when I replaced the alternator. Also, after I put a power steering bracket bolt back in and tried torquing it to 45 nM using a 12 mm 1/4 socket on a 1/4 to 3/8 adapter on a 3/8 to 1/2 adapter, the 12 mm 1/4 socket sheared off before I even got to 45 nM. LoL. What ever
Well at least now I know the wiring is ok. Logically the problem should now be fixed. All I have to do is test it.
Those tags are garbage. All of the 6 alternators for that malibu that were bad out of the box all had tags that showed good as well.The alternator was remanufactured by Remy. It came with a test result tag.
