I have a 2004 Chevy Silverado 6.6. When I bought the truck I put new batteries in it and after a few months the passenger side battery started boiling, I checked the alternator output and it was reading 14.7 so I changed the battery thinking maybe it had a bad cell. A few months later same thing, so I put in a new alternator and batteries. Then a while later once again same thing passenger side battery leaking, and starter not engaging so I put in a new starter and battery. My question is what is causing my passenger side battery to boil over? is there a isolator switch on there that I should be looking at or some type of relay? I am stuck here...I just can't seem to find the problem and hoping to get an answer soon.
Thanks, any suggestions would be appreciated
