Dust and bugs and power

The cabinet needed a major cleaning. Twenty-seven years of dust and spiders doesn't make for a fun time working inside the cabinet.

After I vacuumed out all the bugs, I plugged the machine in and turned it on to see what would happen. Besides a humming sound, absolutely nothing happened. The voltages coming out of the power converter were all wrong, so the investigations had to start at the power plug. The cord goes into the bottom of the cabinet and is connected to this small city:

I measured the voltages coming from the wall and found out that the ground wire was broken somewhere. I wanted to replace the power cord anyway. So, I removed the small city and soldered on a new cord.

Next step: Hook the small city back up and see what happens.
