Links: The incurable noticeable "+" is for favorable volts. The incurable noticeable "-" is for ground. These must be connected for the indicator to record battery use. With just these two terminals connected, there will certainly be no display showing. This is done to conserve battery power, however the meter is monitoring the batteries When you want to see the display, link the incurable noticeable "C" to a positive volt source (+ and - terminals must still be linked). "C" can be difficult wired to have the display revealing all of the time or can be used through a temporary contact switch to see the battery status by depressing the temporary contact switch. Another technique for installation would be to link "C" to a terminal coming from a switch key that goes hot when the key is turned on. Keep in mind that + and - must always be linked.
