Im having a few problems setting up my LC1. I had the LC1 wired to my DIY PNP MS (Built by Brain) through the DB15 (I think its called!) port on the MS.
I had 4 wires from the MS going to it. Thye Brown wire, The Blue and White wire, And the Red Power wire. The Black wire was connected to an push button and LED but I wasnt sure it was working so I removed it to eliminate that as a possible fault.
I have never calibrated the sensor form install as Im not certain its calibrating. I have tried earthing out the wire etc but cant be sure it worked.
I think it could be an earth issue. I tried cutting the blue and white wires and earthing them direct to an earth near the stereo and the gauge needle went all the way round to the right back to the left and then back to 18 and stopped at 18. Is this correct? should the gauge do this?
How do you calibrate without the LED connected?
I have tried to power the LC1 then connect the sensor but there is no visible difference. I also connected the black wire to earth but still no difference.
However when the blue and hite ire went to the MS direct if I attached the black wire to earth the gauge did look like it was doing something. But again I was uncertaiun when it was stopped so I dont know if its worked.
I have read the LC1 handbook an still I cant be sure its correct.
Wiring summary is:
White and Blue to earth (was via the ECU)
Red to ECU (Power I assume)
Black and yellow wire taped up seperate
Brown to Ecu.
