Sorry, should have added the link for the install instructions,

Ok switched the white out of the 12V to the brown on the controler and the yellow to head light power, programmed. Everything is reading fine...now instead of staying at 22.4 its just stays at 7.4 and doesnt change.

Try this without starting the car turn the key to ACC position and let the gauge warm up. My flashes 7.4 during warm-up and then reads 21.8 (I think when car is off). If your gauge does not do this try recalibrating by:

- Unplugging the sensor from the LC1 controller (unclip the two).
- You might as well at this point unscrew the sensor from the bung and let hang.
- Turn the key to ON ( don't start the car) for 10sec and then turn OFF
- Plug the sensor back into the controller.
-Turn car to ON (Don't start it) and let it do its thing. The LED will flash slowly than fast and when it goes solid the heater is calibrated.
- At this point hold the calibration button for 3 seconds (light will go off) and then release. This does the free air calibration.

Doing these steps will clear and then set the calibration data (like first time install process).

One other thing....you do have the DB gauge correct (i.e. did the instructions I send you match your gauge)?

Ya im pretty sure i did the right one because the other one has different colour wires. I will try it when im at work tomorrow and put it on a hoist dont feel like jacking it back up right now lol.

Are you powering the controller with a circuit that is hot while cranking? IIRC there was an issue with the controller dropping under a certain voltage. I think it was recommended that the controller be wired to a power source that is 12v when running, 0v while cranking.

This may not have anything to do with it, just throwing it out there.
