I thought I connected the new switch correctly as I used the old one as the example. Fast forward: now connecting the inner fender wiring harness and the headlight leads. I am getting only high beams. Could be I’m just not in correctly connecting wires. I have power to the bottom 3 terminals of the fuse box. The upper 2 terminals (high and low beams);won’t light the test light on either high or low beam. I’m now rechecking the wiring diagram and tracing the wires. When I click the dimmer switch to high beam I at least get a current flow. When I use low beams.....nothing. My question is: Could I have crossed/incorrectly wired the dimmer switch that would cause the hi/lo beams to not work correctly? Will check with a meter but I thought I’d ask smarter folks for ideas. | | |
