This thread is a restart off of the OP's other thread about the problem
here.
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.
