[QUOTE="East, post: 8649477, member: 644796"] So I have a Mechman 260a, ran it in my 02 trailblazer until I blew the transmission. I put the alt into my 04 Trailblazer and it wasn't holding voltage. So I sent it out to Mechman to get fixed and got it back and it the voltage is great. My issue is the rpm's as jumping like crazy and the alt is whining bad and revving with the rpm's. It never did this on my 02 trailblazer. I did the Big 3 in 0/3 and the grounds are in the same places I'd normally put them. Is this normal? it the alt fucked? anything I can do to rest grounds/amperage? I have a DMM and a Fluke Clamp. Heres a video: [MEDIA=youtube]k2E6XMv7pJk[/MEDIA] [/QUOTE]
