Batteries or alternators charging to much?

On my m1008 with 6.2 thats still 24volts, my volt meter (the one thats on the right hand side where the a/c vent would be) is going all the way to the right, pass the green and now in the orange. And like my head lights and dash lights seem alot brighter than normal, or at least when Im on the gas, when I let up they dim a bit. But it just started all this a few days ago. Is this normal, or is there something wrong with my junk.
 
THe voltage regulator, which is contained within the alternator, has probably gone out to lunch. You need to replace the alternator(s) most likely.
 
Can you hear more altenator whine? That would give a clue that the altenator is putting out a lot of power.

How about your battery? Does it stink like a bad egg yet?
 
If your lights get brighter when you rev, then the alt is working. I have never seen a volt reg go bad, and still charge. I suspect a bad/weak battery.
 
Well my batteries crank fine, and I havent heard my altenators whine yet. Is it bad that the needle is all the way to the right, in the orange(its not in the picture cuz it wasnt running, but when it is running thats where it stays)

Sounds like you are overcharging to me. You'll find out, as the batteries will start to make a sizzling sound and stink with a long continued hard overcharge.

haha sweet! anyway prevent this?
 
I have seen many alternators with a bad voltage regulator that overcharged. That is the only thing capable of an overcharging system on a normal setup. The only other possibility that crosses my mind in your situation is if the 12/24 isolator is bad. Most likely the voltage regulator though. Pull both alts and have the m tested. Easy and free.
