Did my alternator kill my FICM?
So last week my truck finally died. It had been getting harder to cold start in the mornings, and I honestly never even considered the ficm till that day. The voltage was low so I pulled it and sent it off to swamps for repair. I figured bows a good time for a HO alternator so I ordered a 190amp from dc power. Anyway, I got everything put back together today and the truck fired up sooooo fast(faster than ever before)and to my suprise it's not belt chirping anymore.
I had "the chirp" for 6-8 months before and checked the alt, pulleys, replaced the belt but it wouldn't go away. The factory alternator always put out 13.5+ so I never thought it was bad. Just wondering now in hindsight if the alt slowly dragged my ficm down and out?
