So I get the rebuild done and used a little motivation on getting the alternator back into place, but nothing out of the ordinary.
Started to get the "M & S" light flashing occasionally, every now and then rough shift, the head unit would intermittently flash off while driving, and an odd light flicker when the rover was shut off... all sporadic in nature, nothing seemingly linked.
I ran through all the wiring for the battery, making sure it's clean, seated properly, and double checked the grounds - the engine block grounding straps are the only ones I messed with during the rebuild, clean and secure. Double checked the wires in the back of the alternator, those look clean and secure.
Doing some research, and luckily I also just got an CEL for system voltage low, it looks like the alternator is not putting out enough juice.
We just got pummeled with over a foot of snow and sub-artic temps so it might be a minute until I get to pull the alt and go get it checked...
Somewhere between insanity and stupidity is sheer brilliance...
Just start the truck and stick a multi metter on the altanator. It should be charging 2 volts or so over battery output. I made the mistake of buying a rebuilt alternator also and I have to replace it every 3-4 weeks on the dot. They are so crappy. Always go original on electrical. Batteries too. If you cheap out you will get all sorts of crazy shit going on.
