umm have you checked the fuse under the hood labeled "head"?

yah thats good all fuses are good....one works one doesnt

Have you checked power at the plug?

yah getting power to the plug....

yah getting power to the plug hi and lo.....it is baffling me

If you're getting power to the plug, and both filaments in the sealed beam are OK, then the third wire (the ground wire) must not be attached to good metal ground.
