1982 300CD, weird electrical problem
When I was working on cleaning the banjo bolt to the ALDA a tool inadvertently arced from the battery to ground for a split second. (Who hasn't done that?) Afterward, the fuse to the dash gauges went out. So, I replaced it. Replacing that fuse made it so the gauges now work. Not not the dash lights. Now, I notice that the tail lights don't work and the dash lights don't work. I don't see any blown fuses. Any ideas what wire could cause this?

Don't rely on a visual inspection of fuses, a test light or a VOM is needed to confirm that voltage comes into, through and exits the fuse. If you don't have a test light they are a necessary tool and are inexpensive. For now try rotating all of the fuses in place that have anything to do with the circuit in question. Fuse maintenance/cleanliness will keep many electrical gremlins at bay on these cars.
FWIW, I doubt you damaged anything due to the arcing. Good luck!!!

Electrical Testing
The test light is your best friend, don't buy a cheapo one, buy a good quality one with a long cord, NOT COILED ! .
If you've not done so yet, replace every fuse that's gray / silver in color .

Could also look for a test light with a built in voltmeter.

Just a wild thought, have you tried pulling a bulb and seeing if it’s burned out?
Maybe the arc took out a few bulbs?

So, I disconnected the battery and with the fuse cover removed, I removed the 8mm nut that holds the fuse panel to the frame of the car. This way, I was able to get a look at the wires leading to the fuse panel. I wanted to see if any of them were burnt or disconnected. It all looked fine. I put it all back together and now everything works fine!!!
I'm sorry I was not able to find the exact cause to report in case others have the same problem. But, thanks for your suggestions!!

Did you test the fuses in the manner suggested?
