Hi guys. Ive lost lowbeam on my headlights but high beam works fine. 2020 np300 SL. I was wiring in a boost gauge and used a multimeter to find illumination wire on the difflock button and thinking that blew the ipdm? Gauge works fine and it was all done with battery disconnected apart from using the multimeter to find illumination. Checked the lowbeam fuses and they seem fine. No errors or warning lights either. Any help would be appreciated, cheers
