How many Volts are normal?
I put a volt gauge in my truck not long ago and it is almost always around 14-15 volts. Im starting to think the alternator is the culprit. I have two swelled Optima Red top batterys in the truck, I had two before that I returned because of the same problem, I know they are not rated for our trucks.... now..... I didnt know then. I didnt put 2 and 2 together when I had the problem with the first set. What do you guys think? Thanks

If you have dual batteries maybe the (the name escapes me) thing where the two batteries meet up is bad and the regulator cannot switch between batteries and charge the correct battery that needs charging anymore. Whats that dam thing called

There isn't any "thing where the two batteries meet up".
They are simply wired in parallel, and the regulator doesn't have to look at one then the other.
You may be thinking of an "isolator", but these trucks don't use them.
