2 1/6” Ultragage instructions
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:
Vacuum/Boost Gauge
Gauge, sender and switch wire connections using Cyberdyne MAP sender.
Red Wire: Ignition Wire, hookup to a switched +12 volt source. Example: Accessory fuse in fuse box.
Black Wire: Ground wire, mate the black wire from the gauge, switch and the uncoated wire from the MAP sender together and hookup to a good ground. Example:
Purple Wire: Dimmer wire, hookup to a switched light sourec. Example: Any switched light bulb.
White wire: Signal wire, mate the white wire from the gauge with the clear wire from the sender.
Yellow Wire: +5v accessory wire, mate the yellow wire from the gauge to the black wire from the sender.
.
Note: All wires should be routed away from the ignition system, spark plug wires or any type of electrical noise imposing wire. Any wire brought through the firewall should be secured through a rubber grommet.
Understanding And Setting The Warning Indicators
The chart below lists gauges, their operating range and four indicators. The gauge will flash as a warning that readings are getting close to being out of normal operating range. The gauge will scroll “hi” or “low” when readings are completely out of normal operating range.
Vacuum/Boost
Range: 30.0 IN-HG – 23.0 PSI
Low scroll: None
Low flash: None
Hi flash: None
High scroll: 7.0 – 23.0 PSI
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 srep 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.
Special Functions
Vacuum/Boost:
1. The gauge display will flash when in boost. This allows for easier distinction between the two different gauges.
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 +12 volts is supplied to the red wire.
4. Test gauge by hooking up directly across battery. Red wire connects to the + terminal and the black wire connects to the - terminal. The gauge will light up and display, scroll, or flash something, if functioning properly.
Fuse always blows:
1. Check the amperage rating on the fuse. It should be at least 1 amp.
2. Check all wires external to the gauge. Make sure none of them are shorted together or to ground.
3. Make sure all wires are connected to the proper input.
Gauge does not dim:
1. Check the connection to the purple wire. Make sure there is +12 volts when the headlight switch is on.
2. Test the dimmer wire by hooking up to the + terminal on the battery after disconnecting purple wire. 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' Ultragages:
Gauge will not go into adjustment mode:
1. Make sure there is +12 volts to the dimmer wire before the gauge is turned on.
Gauge always goes into adjustment mode:
1. Make sure the dimmer wire is of or no voltage is applied to the purple wire before the gauge is turned on.
I'm in adjustment mode, but when I turn the pot the gauge does not change:
1. Call 724-258-8400 for technical assistance.

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 related to small 2 1/16' Ultragages:
When button is pushed the gauge does not show the lo and hi memory recall functions:
1. Check blue wire connection from the gauge to the switch. With the switch not pushed, there should be about +5 volts.
2. Check black wire connection from the switch. It should be ground.
3. Test the memory function by touching the blue wire to the black ground wire on the gauge. Once grounded the gauge should show the lo and hi memory recall readings.
Gauge will not go into adjustment mode:
1. Make sure there is +12 volts to the dimmer wire before the gauge is turned on.
