Voltage Gauge Reading Low. The most typical reason for a battery voltage gauge going up and down is a failing alternator that cannot deliver a constant and consistent charge. when you see the dash gauge indicating low voltage, cross check it against the portable voltmeter; when you start your car, the battery voltage gauge should show a reading of around 12.6 to 14.4 volts. oluseun, with the engine running the gauge should measure the output of your alternator. Read the voltage on the multimeter. The needle should be indicating anywhere above 12.5 volts but below 15 volts [1]. A reading of 12.6 volts or more indicates that your battery is. in this post, we’ll discuss why a battery voltage gauge would go up and down, and how you can fix it. The low voltage may be. read the voltage: to read the battery voltage, you need to look for a needle indicator on the gauge. check your battery’s voltage reading for a consistent level below 12.4 volts to identify potential signs of undercharging.
