Voltmeter install on a 2007 RX 350

Your right but what i am talking about is the voltage drop when the car is started. This will give you an indication of the battery condition under starting load. If the volts drop to say 7-8 volts during starting it is probably time to start addressing an up coming battery issue. As soon as you start turning over the engine the power to the power outlet is off until the key is back in the run position. When a battery is tested it must have a good sized amp load to check the true condition of the battery. This is what they do when you have your battery tested, they put a heavy load on it an watch the voltage drop. When the lead plates are almost depleted in the battery it won't sustain the heavy load and the volts will drop and your cranking amperage will soon become to low to start your car. This is when winter cold temps really take there toll on older batteries.
No big deal just wasn't sure what the OP was looking for with the volt meter install. like I said I have a radar detector with volts display and love it.

Just replace my battery and the indication was a long cranking time of the engine before it would fire, not slow just 15 to 20 seconds before it would start. All other functions worked as they should and the clock never reset to midnight like I have heard others say. I guess the mild climate here in Calif. doesn't hit the batteries so hard.
