well my alternator went out on my sr so I replaced it and now im getting random voltage readings on my timer I know its not the timer because the lights on my dash are really dim. Started out normal charge 14.v then i hit boost voltage dropped and has yet to recover back to 14 now its running 10.5 and struggles up to 11.3 or so i have battery relocated to trunk replaced battery ground and terminals positive has a little green when i stripped wire to redo terminal so is suspect it has more.

I'd check all the connections on your alternator, something might be lose.

they are all tight there is a small amount of corrosion through the positive cable though and there is a weird sound coming from under dash on driver side kind of like how a low gauge wire sounds when it shorts but I cant find it so annoying

any extra power being drawn from the battery itself to run any sort of amps fans or guages?

Sounds like the power supply to the battery is faulty. Just get a dvom and check the positive on the alt and see what's the reading
