If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. So even at idle you should register the 14.4v (approximate gauge reading could be different of course). #3 · apr 25, 2009.

Needless to say i tested the car with it running and sure enough the gage in dash was reading 12v=14.2 for the car in reality. The generator may exit fuel economy mode if additional voltage is required.

Simply let the car idle and check the voltage at the battery with a volt meter. The ipc voltage gauge displays the system voltage as received from the bcm over the gmlan serial data circuit.

Assuming you have 12 volts or more with the key off if your voltage reads higher on the battery while running than it does when its turned off your good moving or not. #3 · apr 25, 2009.

The gauge waits for a voltage reading of at least 13.5 before it starts heating the sensor since 13.5 and above indicates the charging system is running. The battery light in the dash flickers on and off.

If you have one of those that shows the voltage without the engine running, then check your gauge for a bad resistor on the dash panel. Voltage should stay the same while amperage goes up and down, depending on what the car needs.

With that switch closure, the gauge is connected into the battery circuit. I was riding the other day and looked down and my volt gauge was reading 12 volts at idle.

This is typical of a properly operating charging system. The battery light in the dash flickers on and off.

At Alternator With Vehicle Running:

At battery with truck off: I just replaced my alt. What should my alternator gauge read?

With That Switch Closure, The Gauge Is Connected Into The Battery Circuit.

The low voltage may be indicative of issues with your alternator. If the voltage reading drops below 12.5 volts, the charging system is not operating properly, and the battery is having to provide current, meaning it will eventually go dead. You mentioned your voltmeter runs at about 15 volts most of the time.

If The Meter Reads Any Higher, The Batteries Are Really Drawn Down, And May Be “Dead” Or Dying.

The battery light in the dash flickers on and off. Readings of 14 to 14.5 volts on the gauge when as a good sign. #3 · apr 25, 2009.

If you have one of those that shows the voltage without the engine running, then check your gauge for a bad resistor on the dash panel. Simply let the car idle and check the voltage at the battery with a volt meter. Look at the voltmeter while the engine is running.

Mines Reads 14.8 When Started Cold, Then Settles To 14.1 After It's Slightly Warmed Up.

If you look at the gauge there is top dead center line. Voltage regulator caps the voltage to 14.4v regardless of load. If the voltmeter reads more than 14.5 volts, you may have a.
