Battery charge gauge for most M-series vehicles. Also used on the MEP-002A/MEP-003A diesel generator sets. Please note this is a voltmeter, not an amp meter, and cannot replace amp meters used on some early M-series and WWII era vehicles.
Gauge is for use with 24 - 28 volt systems. Actual indicating range is 19 - 32 volts. Tic mark in green square at 27.6 volts.
The gauge does not require a sending unit. Mounting hardware included. Damped gauge pointer for stable readings. Gauge must be properly grounded via the mounting bracket to function correctly.
