    Thank you Rich. Yes this is a continuation of the same problem. I found this wire and had hoped it might have been the problem but I can see it is for the buzzer. Being hopeful of an easy fix... I will go through all the suggestions and see what I can find out. Electrics are not my thing but I enjoy a challenge.....

    In that thread he reported that the high beams do not light regardless of stalk position including the pull-flash position. He also reported that swapping the high-low relays changes nothing.

    There was a post (#14) in that original thread suggesting he check Fuse 15 [High ("Main") Beam] to see if it's OK, also to check for +12V on either of the Fuse 15 terminals - with fuse out - when high beams are supposed to be ON.

    Did not yet see an answer about that.

    Thank you Ron. I should have continued from the same thread.

    NP!

    I think you would find your problem if you followed the steps in post #16.
    (PM me anytime if they are unclear or you have any questions....)

    The last component in the high beam circuit before the dash lamp and the 4 high beam filaments (all in parallel to each other) is Fuse 15.

    Suggesting you check that fuse and voltage to fuse just to easily rule it out.

    Ron's troubleshooting method and schematic is worthwhile for verifying stalk switch is doing its job additional to checking voltage at fuse.

    I don't see it being Fuse 15 at this point -- It doesn't Flash either (Fuse 6)...Could have been both, but 15 has already been checked (post 1....and verified).
    It will fail step 3 if Fuse 15 is bad. And the Flash part of step 4 if fuse 6 is bad (test while in low beam mode).

    Right, Ron. I did miss the 'checked fuse' report in this thread.
