lane A light fault

gently pull on the CPU side lane A HIC connector wires for lane A light. If moves chances are that the one of the pins is not seated properly in the connector shell. Also push on that wire on both sides of the connector and see if light operates normally. Sometimes following the wire into the connector from the back side of the connector with the extraction tool will seat the offending pin. When you say "continuity is good from connector to light" do you mean that when measured from the connector half on the light side or do you mean , when the connectors are mated and if so where did you place the meter probe to measure the mated connector of the CPU side?

Hi Thanks for the advice.

I put a wire to a multimeter on the CPU side of the HIC A connector and other end to the wire light. Thus the fault is not my wiring!

The Skyview shows all of the engine instruments,(they appear to be working, temperatures and volts are correct, rest show zero, when switched off they have a red  X)  they also turn off when Lane A and Lane B are switched off. The information getting to the Skyview via the CAN connection shows 'Fault Warning LT Lamp A.'

Problem solved!

In trying to fault find I removed the LED warning light (which I had tested) and used an ordinary auto warning light. Not noticing that it was 2 watt.

Rotax pointed out that the max amps for the warning light was 120mAmp. Which gives a max of 1.4 watts. Thus a bulb of .6watt too big was enough to prevent the light working. On changing the bulb, all worked. The reason it did not work was the resistor in series with the LED was a dud. I had tested the LED but not with the resistors!
