Warning: Before doing any work on any kind of vehicle, disconnect the negative (-) battery cable. Failure to do so may result in burns, electrical shock, or other personal injuries and damage to vehicle.

Recommended installation technique:

1. Decide on a location to mount the gauge(s).
2. Drill, cut and do whatever it takes to get the location ready to install the gauge(s).
3. Install the sender(s) and switch(s) , if applicable. Refer to section 'sender installation'.
4. Install the gauge, but do not secure into place.
5. Make all wire connections. Refer to section 'Gauge, sender, and switch wire connections'
6. Make sure all gauges are functioning. If any problem refer to the section 'trouble shooting'.
7. Adjust warning indicators or fuel tank capacity. Refer to section 'understanding and setting warning indicators' or ' setting fuel tank capacity'.
8. Secure the gauge in place.
9. Read over sections 'memory recall and 'special functions'.

Gauge, sender and switch wire connections:

Red wire: Ignition wire, hookup to a switched +12 volt ignition source. Example: Accessory fuse in fuse box.

Black wire: Ground wire, mate all black wires from the gauge, sender, switch, and hookup to a good ground. Example: Battery (-) terminal.

Purple wire: Dimmer wire, hookup to a switched light source. Example: Any switched light bulb>

Blue wire: Memory recall wire, mate blue wire from the gauge to the blue wire on the switch.

Note: All wire should be routed away from the ignition system, spark plug wires or any type of electrical noise imposing wires. Any wire brought through the firewall should be secured through a rubber grommet.

Warning Indicators

Below is listed the operating range and the four warning indicators. The gauge will flash as a warning that the readings are getting close to being out of the normal range. The gauge will scroll hi or lo when readings are completely out of normal operating range

Volt Meter 8 - 18 Volts

 Range: 8 - 18 volts

Low Scroll: 10.0 Volts

Low Flash: 10.0 - 12.0 Volts

Hi Flash: 15.8 Volts

Hi Scroll: 16.5 Volts

Volt Meter 8 - 30 Volts

Range: 8 - 30 Volts

Low Scroll: 10.0 Volts

Low Flash: 10.0 - 12.0 Volts

High Flash: 27.5 Volts

High Scroll: 27.5 Volts

Each gauge can be looked up in the chart above to ascertain which warning indicator is adjustable. The warning which is adjustable is marked with an asterisk. To adjust your warning indicator proceed with the following steps:

1:  Turn off the gauge.

2. If the dimmer wire is connected to a switched light source, turn on your lights. Otherwise place a +12v to the purple wire.

3.        Turn on the gauge. At this point the gauge should be on and displaying a flashing number. If the display is not flashing then repeat steps 1  3, other wise go onto step 4.

4.        4.  The gauge is now in adjustment mode. Turn the screw located through the hole in the back of the gauge until the number on the display is what you would like your warning indicator to be set at.

5.          Wait 30 seconds to make sure the desired number stays displayed. If the number changes repeat step 4. If number holds then turn the gauge off.

6.        Turn off your lights or remove +12v from the purple wire.

7.        The warning indicator is now set and can be checked anytime repeating steps 1  3. To re-adjust your warning indicator repeat steps 1  7.

Memory Recall

1.        Make sure the switch is wired up properly as per the gauge, sender and switch wire connections on page 1.

2.        Press the switch. The gauge will display lo, then display the lowest reading, then the gauge will display hi, and then display the highest reading. All readings are from when the gauge was turned on.

Troubleshooting

Troubleshooting related to all gauges:

Gauge does not light:

1:  Check to make sure of a good ground

2.        Check the fuse if used.

3.        Make sure +12v is supplied to the red wire.

4.        Test gauge by hooking directly across battery. Red wire connects to the + terminal and black wire connects to the  terminal. The gauge will light up and display, scroll, or flash something.

Fuse always blows:

1.        Check the amperage rating of fuse. It should be at least 1 amp.

2.        Check all external wires to gauge. Make sure none of them are shorted together.

3.        Make sure all wires are connected to proper input.

Gauge does not dim:

1.        Check the connection to the purple wire.

2.        Test the dimmer wire by hooking up to the + terminal on the battery. When connected the gauge should dim. When not connected the gauge should, within a few seconds, be bright again.

Troubleshooting related to small 2 1/16 Ultra gauges:

1.        .

Gauge will not go into adjustment mode:

1.        Make sure there is +12v to the dimmer wire before the gauge is turned on.

Gauge always goes into adjustment mode:

1.        Make sure dimmer wire is off or no voltage is applied to the purple wire before the gauge is turned on.

Im in adjustment mode, but when I turn the pot the gauge does not change:
