VOLTMETER GAUGE
INSTALLATION INSTRUCTIONS
A voltmeter measures the voltage between the two
points where the leads are connected. Most vehicles
exhibit between 13 and 15 volts while being
operated above idle speed. Check your owners
manual or dealer for a more exact normal voltage
for your vehicle. A voltmeter is useful in that it
can give a warning of many electrical problems.
PRECAUTIONS
1. Follow the instructions carefully for the sequence
of nuts and washers on the connection posts
of the voltmeter. Refer to Figure 2.
2. Disconnect the battery ground cable before
performing any electrical work.
3. Route all wiring away from linkages, engine
parts that become hot, or moving parts.
4. Never smoke while working on your vehicle
and always keep a re extinguisher nearby.
It should be rated for gas/chemical/electrical
res.
5. Never lay tools on top of the battery or wear
jewelry during electrical work to avoid severe
electrical shorts.
6. Locate and operate gauges so that driving
visibility is not compromised.
INSTALLATION
Make temporary test connection before permanently
mounting hardware or drilling holes.
This gauge can be mounted into any surface or into
a gauge pod. Refer to Figure 1.

3. If you are installing the gauge into a surface (for
example the dashboard) make a 2-1/16” hole
for the gauge.Do not accidentally cut any wires
or hoses. Be sure there is clearance around
the hole for the gauge mounting bracket.
4. Connect a length of 18-gauge insulated copper
wire to a good ground source. Be sure the
grounding surface is a good ground source
as not all metal surfaces inside the vehicle
are well grounded. This wire should be long
enough to reach the voltmeter’s mounting
location.
5. Connect another length of 18-gauge wire to
a location on the fuse box where the wire will
receive power whenever the ignition key is in
the START, ON or ACCESSORY positions.
This wire should also be long enough to reach
the voltmeter.
6. After mounting the gauge, the wire from the
ground source (Step 4) should be connected
as shown in Figure 2, to the voltmeter’s connection post marked “–”.
7. The wire from the fuse box (Step 5) should
be connected as shown in Figure 2, to the
voltmeter’s connection post marked “+”.
NOTE: Do NOT leave any hardware out of these
connections.

1. Disconnect the ground cable from the battery.
2. Choose a location to mount the gauge where
it will be viewable from a normal driving position.
8. Connect the blue and white wires using either
Figure 3a or Figure 3b.

cable, you noticed sparks or any of the wiring
getting warm, check that all connections
are properly located, and insulated from
grounding.
2. If the reading on the gauge stays at the lowest
marked voltage when the ignition is switched
on, then try reversing the wires on the gauge’s
connection posts “+” and “–”.
3. If the gauge reads lower than you expect, check
all connections, especially those to a ground
source. A poor connection causes resistance
which gives a false low reading.
