My 1984 MB 300SD dash board was not illuminated due the bad rheostat (pot).
After removing the entire dash board and crossing the pot and installing the dash board again, it did not work correctly. Lights were replaced but not all of them are working correctly and some of them no longer working. It is worse than before. For example: light for glow plug is not working, brake light is on all the time, high bean light indicator is not working, seat belt light and battery light are not working, fuel gauge is showing empty after the car starts. Other instruments like RPM and speedometer is working correctly.
The car is running but cluster is not. All fuses are good including the cluster fuse.
I tested few times but I was not able to get it working.
Please give me some help to get it working again.
