PILOT LIGHTS NOT WORKING

<< < (2/3) > >>

Johnny4428:
Just to say I have just gone through similar problem sorry if I’m pointing out the obvious but none of mine worked either and it was due to corrosion in all bulb holders. Removed the bulbs and holders from bike and cleaned. Al,now working, but think I will probably replace at some point.

Hi Jonny4428

Thank you for you up date on having a similar problem from what I can see the bulb holders are mint and looking in very good condition  :) I am starting to think the following,
 
1) Indicators work as hazard lights on the Pilot cluster that proves the inside 
     cluster return earth is ok just need to sort individual L/H & R/H pilot wires

2) If i apply switch power to the black wire going to the pilot cluster I don't get either the
    OIL PX or the Neutral light When I apply a direct earth back to the battery via the green
    wire so i am thinking is the black wire is broken up inside the cluster ????

3) If I have continuity with the Clutch lever on the handle bars is not pulled that is going to 
    give me a circuit back from the light back through the lever to earth ??

Gromitdog:
PILOT LIGHT FIXED ;D ;D  it was traced down to the black and green wires in the cluster loom internally broken where they join two wires into one of the same colour, Also the Blue headlight wire up to the jewel light was also broken internally.
This just goes to prove even though it was working when I last rode the bike 2 weeks ago these 40 year old wire a fragile ..................

Johnny4428:
Very satisfying to get to the bottom of it and get them working. I couldn’t chance a start up on my bike until I had at least the oil pressure light working.

Hi Jonny 4428

Very true other wise you could be in big trouble further down to road so to speak.
