Recently pulled my dimmer to turn on the high beams, when I did, there was a surge and I lost all 4 headlights. 1988 K5, 350TBI. I have since been able to get my low beams back, but when I try the highs, there is nothing. I have checked power to the switch and out of the light switch and it's good. I have power to the low beam socket, but not the high beams at the core support. Someone told me that the dimmer switch shouldn't be energized because it only functions to switch ground from low to high and there shouldn't be power to it. If that is true, shouldn't my high beam socket + wire be energized 100% of the time as with the low beam +? If that's the case, can I just piggyback the positve power from another source temporarily until I get it fixed correctly? I also have noted that when I click the dimmer, I do lose power at the low beam socket which means if the theory of the ground switching is true, that's not functioning right. Any help is appreciated in advance. THANKS!
