If there is an alternator or system failure, the voltage reading will be low and drop as the battery discharges. In the case of an overcharge condition, the gauge will climb above its normal zone. There are pre-set alert levels (<9V and >16V) to notify you of these changes by altering the gauge backlight to either amber or red. The G52-VA will also notify you with a beep when the vehicle ignition is on.The G52-VA comes equipped with an optional 100A-rated current display. This monitors the amount of current to or from your main or auxiliary battery. To equip the gauge with this functionality, purchase the REDARC Hall Effect Current Sensor (GS-AMPS).Connect the G52-VA to a vehicle with a 24 volt ignition via a REDARC 24 to 12 Volt Adaptor (GA-2412V) but know only a 12 volt battery can be monitored. The gauge is made of satin chrome bezel and comes with 13 backlight color options.There are multiple alert levels that will notify you as your battery voltage drops below 9V or climbs above 16V. The display illuminates with park lights turned on so you can check battery health without turning on the ignition.
