lc1 completely quit!

Only thing I did was bolt my ecu in rather than let it sit on the floorboard. The unit worked yesterday and now it does not. I have checked the wires and see nothing loose. I get no active signal to link or the gauge. The gauge wont even turn on and link sits at 7.3 Afr with no movement at all.

I would double check the connections on the wires where you spliced them.

You made sure the sensor is plugged into the LC-1 unit itself as well? Sounds like the reading it gets when it's unplugged.

Make sure the blue and white wires are grounded too.

Ok my gauge and the main unit are on separate power sources. So would the unit not getting power also cause the gauge to not illuminate?

7.3 is exaclty what mine reads when I turn the power off to it.

Found it. Im sourcing power from my turbo timer harness and the harness was disconnected. Time for zip ties.
