I'm Awesome
Ive got a 92 K1500 Suburban 5.7l 148k miles
So... I finally got tired of jumpstarting this thing (not my daily driver)
Had the battery tested and was shown as being bad. Alt tested good.
I found that the + post on the alt was loose. So I replaced the alternator... the battery was still crap. So I replaced it too.
Here I am, new battery and alternator. I have read some past posts and have checked the (-) cable and it checks out fine, I removed it from the stud on the intake and cleaned it up just in case. Checked continuity and all is well.
I take my meter and with one lead on the (+) post of the alt and the other lead grounded on the engine I am only showing 11.8v coming from the alternator.
What am I missing?
Also, I have been having terrible power lately. Would running 10-12v cause performance issues at all?
