Wayne: Bypassing the wire should have worked *UNLESS* if the wire with no continuity had a ground, it may have damaged the contact in the hi-lo beam switch. Check for power coming from the switch at the "18" plug. If you have power there, then a jumper wire from there to #18 on your headlights should result in light unless your lo beams on the lights are burnt out.
Chris:
The description you give is typical of the results of a short to ground on any one of the turn signal wires. The first symptom will be that the indicator light will not flash when you are signaling a turn, but rather will stay on steady. If caught early, the solid state flasher can be saved, but if left for a while it will be fatal to the flasher. I have also seen points in the control arm burnt as well. There was a modification on the M151A2 family to prevent some of this: an inline fuse was installed in the main power wire into the turn signals.
