Ok, I had a thread previously and now am expounding on the original question. So I had a kit from DDM Tuning, 35W slim ballast kit, in my headlights. Had a ballast problem, got it swapped out, no big deal. Then one night, my headlights stopped working altogether. Tracked the problem to the relay, they sent me a new one, low beams worked, but highs would not. So I said screw it, I'm gonna do a retro-fit. Got the FX-R stage 3 kit from TRS with the morimoto ballasts and bulbs, H4 wiring harness, and FX-R projectors. Got them installed without issue, until while testing, the driver side high beam stopped working. Swapped the whole assembly to the passenger side, worked great, but not on driver side. Checked all my connections and fuses and everything. No dice. Matt sent me a new relay for the wiring harness, which caused my drivers low-beam fuse to blow in my under-hood fuse box. Never would work. Original relay that came with the kit still working both side low beams, passenger high beam. When I plug the stock headlights back in, both highs and lows work fine.
My question is: Is there something in the wiring that could be causing these relays to go bad on my highs? I've grounded my driver side to the main ground where the battery is grounded, and I know the ground is good. The only fuse that should matter in the whole set-up is the driver side ones, b/c that's where the H4 harness is plugged in. All my fuses are good though. Anybody got any suggestions?
