FJ40JOHN
SILVER Star
All of the gauge lights and running/parking lights are out on my 1997 LX450. I've done a bit of research, and found that they are on a shared circuit, but I am electrically stupid (even after watching these... Learn Electrical Troubleshooting !). Headlights, brake lights, signals, and all dash lights work fine.
I have 12V on both sides of the fuse with the ignition on. I've swapped fuses anyway, just to see if anything changed. It didn't. I've checked all of the marker bulbs and they seem fine. Didn't tear into the dash to check the gauge lights.
I think I have checked most if the wiring to the corners. The grounds show resistance when tested to a bolt or the frame. I would expect to see 12V on the green wire at each socket, but have various results and don't really know what I need to see.
Any tips on where to start? I contacted a mechanic buddy, but he isn't available until next weekend. Currently unable to drive at night...
