What Should Volt Gauge Read

What Should Volt Gauge Read. I know its right because i have a voltage stabilizer w/a digital voltage readout on. So even at idle you should register the 14.4v (approximate gauge reading could be different of course).

Mines reads 14.8 when started cold, then settles to 14.1 after its slightly warmed up. Power from that circuit heats a small coil, which causes a bimetal strip to flex and a contact to close (inside the volt/fuel gauge). At alternator with vehicle running:

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.


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. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage. Simply let the car idle and check the voltage at the battery with a volt meter.

The Voltage Should Remain High With These Circuits On.


What does everybody elses amp gauges read on a 70 bb?</blockquote rc sounds like you are mistaking amps for volts. The ipc voltage gauge displays the system voltage as received from the bcm over the gmlan serial data circuit. If there is no communication with the bcm, the dic display will read all dashes and the voltage gauge will be at minimum until communication is restored.

If you look at the gauge there is top dead center line. With that switch closure, the gauge is connected into the battery circuit. 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.

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.


Voltage regulator caps the voltage to 14.4v regardless of load. Look at the voltmeter while the engine is running. Gave some throttle and went back to 14volts.

So, If You Read Less Than 12.6 Or You Read Too Much Higher Than 12.8 On The Battery Gauge, This Means Your Car Battery Is Not In Good Shape.


The generator may exit fuel economy mode if additional voltage is required. You mentioned your voltmeter runs at about 15 volts most of the time. Readings of 14 to 14.5 volts on the gauge when as a good sign.
