I was driving home Sunday, and about an hour into my trip I smelled that smell. The burning electrical smell.
Stopped at a rest stop and could really find anything thing, everything was working so I drove about another 30min and stopped for a bite.
When I came back out I had no instrument lights when I pulled my headlight switch, and crank with no start. Still had headlights. Checked the fused and the 5amp instrument fuse and 30amp ECM B were blown. Luckily I walked a couple blocks to the parts place and grabbed a pack of fuses. I replaced the ECM B with no problems but the instrument fuse kept blowing, so I just drove home with no gauge lights. I verified tail lights and brake lights before hitting the road.
Monday I was off so I dove in. I pulled the headlight switch and could smell the burnt right away. I took it apart and found this on the rotor
I cleaned it all off and lubed up the sliders in the switch with some bulb grease and everything seems to be working.
Would this blow the ECM B fuse? It's right next to the instrument fuse.
