Instructions

    • 1

      Remove the negative and positive terminals on the boat's battery before mounting the voltmeter.

    • 2

      Select the spot where you will mount the voltmeter. Use a pencil to mark the mounting holes on the meter.

    • 3

      Drill where you marked with a drill. Then use a larger size drill bit and drill a hole in the center of where the voltmeter will be mounted. This hole is where the wires will be fed through.

    • 4

      Mount the voltmeter and tighten it down with the retaining screws.

    • 5

      Access the wire ends on the back of the voltmeter. Determine the distance between where the voltmeter is mounted and where the battery is. Cut one length of wire to size and attach an O-ring to one end. Wrap the loose end to the positive wire running from the voltmeter.

    • 6

      Run the wire to the battery, using plastic ties or electrical tape to secure it along its path. Attach the positive wire with the O-ring connected to it to the positive battery cable and then attach the positive cable to the battery with the wrench.

    • 7

      Connect the negative wire running from the gauge to a piece of ground metal with a screw or a bolt.

    • 8

      Replace the boat's negative battery cable with the wrench.
