Hi,
I only have access to car on weekends so i can only provide updates then. Wlamart said no receipt no new battery lol, but i dont think issue is with battery. I am going to do a voltage drop test. I asked a question at the ericthecarguyforum. I got a very good response. I am going to post below it may help others out. See below guys;
When my car is in battery on position the volt meter in dash only shows 7 to 8 volts but when I put leads on battery(multi meter) the battery is 12.55v. What does this mean?
That means the voltmeter is not reading the correct battery voltage, most likely due to a poor ground. It could also be a faulty voltmeter. The in-dash voltmeters are never very accurate, but even still, it should be reading closer to the correct battery voltage than that. There could also be an electrical fault. There may be high resistance in one of the circuits on the vehicle causing a voltage drop so that even though the voltage at the battery reads good, by the time it gets to the voltmeter it has dropped. The way to test this is with a voltage drop test. The first thing to do is to test the battery voltage with the key on and then with the key off. If the voltage drop only happens with the key on, then the fault is in a circuit that is only on when the key is on. You can find what circuits those are by examining the wiring diagram for your vehicle. If the voltage drop stays the same regardless whether the key is on or off, then the voltage drop is occurring at the battery, in one or both of the battery cables, at the points where the cables connect, or in one or more of the main grounds.
