Q – My gauge pointer stays at the same spot when I turn off the gauge, is this normal?
Q – My gauge does not make a full sweep clockwise before going counterclockwise when I power it up (like the factory gauges in my truck/car do), is this normal?
A – Yes, all electronic EV2 gauges operate as follows: At power-down the pointer remains at the last indicated position (with power removed the pointer cannot move). At power-up the pointer sweeps counterclockwise until it hits the pointer stop (just below “0”) then immediately moves to the level that the gauge is reading at that moment.
Q – My gauge pointer keeps sweeping down to the straight down (6:00) position, why is this happening?
A – The gauge does this to indicate that it is seeing an intermittent out-of-range condition on the sensor circuit. Please go to the appropriate gauge-type section in this document and run the specified tests:
Q – My gauge is not working at all, what is the most likely cause?
A – Check the wiring connection at the orange connector at the back of the gauge, per the troubleshooting guide listed above. The wires are likely not making good contact with the connector terminals. See the referenced document for instructions on pressing the wires in using the tool which is included with each gauge (or contact ISSPRO Customer Service if you need a replacement insertion tool).
Q – My gauges are slightly brighter or dimmer than my factory gauges. Can I adjust the backlighting?
A – You can use the Attribute Programmer R82003 to adjust the dimmer curve, setting the voltage values for minimum and maximum brightness.
Q – Do I need mounting hardware for the gauge?
A – If the gauge is mounted in a 2.040″ hole (typical aftermarket gauge pod) then it is designed for a tight snap fit without mounting hardware. For larger holes a mounting bracket kit R19999 is available.
Q – Do I need anything extra when installing an electronic fuel pressure gauge?
A – All fuel pressure applications except Common Rail systems need at least a snubber valve, and some require an adapter fitting, with specific application requirements listed here: http://www.isspro.com/installation/IS169.pdf
Q – Where do I install the sensor?
Q – Can I view the installation instructions online?
