Automotive Authority LLC® 12V 12 Volt Marine Trolling Motor Battery Indicator Charge Status Power Meter - 2

Connections: The terminal marked "+" is for positive volts. The terminal marked "-" is for ground. These must be hooked up for the indicator to record battery usage. With only these two terminals hooked up, there will be no display showing. This is done to conserve battery power, but the meter is monitoring the batteries When you want to see the display, connect the terminal marked "C" to a positive volt source (+ and - terminals should still be connected). "C" can be hard wired to have the display showing all of the time or can be used through a momentary contact switch to see the battery status by depressing the momentary contact switch. Another method for installation would be to connect "C" to a terminal coming from a switch key that goes hot when the key is turned on. Remember that + and - must always be connected.
