Hair raising incident 140-160

Had an interesting but scary experience the other night. Was driving my '72 144S on a 2 lane Virginia highway, switching from high to low beams as cars passed in the opposite direction. Was travelling about an hour when an oncoming car approached, I switched from hi to low but instead of going to low both lights went out! Switched back to high OK, then after awhile to low. Only happened once but that was enough. Pretty sure it's the relay, but where is it located, on the left fender well? Thanks.

    I've had that happen too and it is quite startling.

    I doubt the issue is with the relay.
    I suspect the problem is that the wires AT the relay have corroded.

    Take the wires off (one at a time so they don't get mixed up), clean then re-crimp or solder (I like solder) the connectors back on or better yet, use new connectors.

    Clean the contacts on the relay too.
    And disconnect the battery before doing all this!

        while you've got that relay out, pop off the cover(unbend tabs below) and check out the moveable contacts. Odds are they are carbonized ... clean them up with wet/dry...polish them up to nice and shiney...with a super fine grit ---1000.
