What should be the correct voltage while the engine is running?
I suppose the Alternator should be producing more than 12v, or it wouldn't be charging the battery would it? But it should also be controlled right?
I've got a dual battery set up, the previous owner had them set up in parallel, but he had a power drain problem because he had the 4 cig lighters and a 10 speaker 4 amp stereo with a DVD player.... it was a show car. Anyway, he installed an isolator that kept the batteries in parallel, but allowed one battery to be cut off from the system with the flick of a switch. So, if I don't have that switch closed, the radio, voltage display, and the power sockets do not work.
When I am running I am getting 14.3 volts, and it only goes up and down by one tenth of a volt or so, when I turn on the AC it drops to 14.0 -- sort of expected, but is that supposed to happen?
I'm wondering because since I connected the batteries to a charger I have not had the cold start problem that I was experiencing right after I bought it. I think it will take another few days of driving and then cold starts to see if it is a real pattern. I'm wondering if the Odyssey batteries, when they get low, may be able to act as if they want to start the engine, but just don't have the power to start it. So they turn it over, but not fast enough, then just die completely after 3-5 tries.
Thanks.
