With a working rectifier, the Battery should reach between 13.4-14.4V when running.
I suspect that could very well be the issue. I installed a new battery charger a couple weeks ago and I did accidentally hook the cranking battery backwards for just a second. Thx for the reply. Ive already changed the voltage regulator on the side. I will look to see if that's the problem.
