Well I have replaced my alternator and put a new battery in and charged it up and put that in and my voltage does not go up at all when I rev the rpms to even 3000 so I am concerned what to do.....my voltage stays around 13 volts regardless of the rpm.....WITH everything off then if I just turn my headlights on it drops to like 12.6....I was hoping for some ideas how to test my wiring cuz I cant think of much, other than I put a new starter in a month ago and thats when this all started......once in a while I would not have much power and be slow to turn over when starting and finally it just all died this week, I am lost right now other than just going thru all the wiring which I really dont want to do.....any ideas???

Have you checked your grounds?

I assume you remembered the fusuble link between the alt and batt.

Is it a new stock Alt, or an upgraded alt?

Is the battery a new Stock battery, or an Upgraded battery?

Where are you checking your voltage?

At the battery?

Or from the cig lighter?

new stock alt.
battery is new upgraded (sort of) I think 780 CCA
I test at the battery and at my distribution block in the trunk
The fusible link?????

run a jumper wire from the alt to the battery, see if this somewhat fixes the problem if it does, u have wiring issues at the starter, voltage should flucate with rpm to at least 14.2 14.4 never 12.6
