Volt Minder 12 Volt Battery Alarm from Universal Power - Part 71730
The Volt Minder 12 Volt Battery Alarm from Universal Power gives a digital readout of battery voltage, and has a settable battery voltage audible alarm. This can prevent starting issues, and battery damage from over-discharge conditions. The readout can also be used to verify battery charger or alternator function. These come with lighter plug adapters installed, but could be hardwired if desired. They have an illuminated LCD, for easy nighttime viewing. The lighted LCD display is a negligible milliamp draw. There are numerous inexpensive digital meters around, most of which are inaccurate up to a couple of tenths, which is huge in battery management. These are among the most accurate we found, down to the hundredths of a volt. These are mountable, or can be used as a portable meter, and are excellent for industrial equipment or any 12 volt battery, or battery system.
Were they removed from your rig ? All wiring removed from terminals ?
No, still connected.
