Battery Isolator
Do I need a battery isolator on my Ford diesel truck?

I have a 1990 ford 7.3 diesel with two 65S Everstart batteries. One battery shows about 13.5 volts and changes very slowly when I rev the engine. The other battery shows about 14.5 volts and goes up to 17 volts when i rev the engine. What is the problem.

THE BATTERIES ARE WIRED IN PARRALELL (that means together) ADDED: Connect jumper cables to both batteries and then check the voltage reading (+ to+ and - to - ) I'll bet that you have a bad cable! ADDED: @ catmandew I didn't mean this was going to help find it, i was using this test to equalize the load on the alternator between the two batteries in case the other battery is marginal! the this still doesn't make sense because it would do the same thing whether it has 1 battery or 6 batteries!
