Hey, just finished up my crack build and had a blast! I was going through and checking all the resistances before I started the voltage tests and everything passed except for terminal 22 which reads in the M ohm range when it should be 0. I was having a lot of trouble with finding ways to troubleshoot this because it isn't connected to anything but the screw on the transformer.
To troubleshoot:
1. I double checked the setup of the washers and screws of the transformer and made sure everything was tight.
2. I checked the resistance of terminal 3 and the safety grounding tab which both read 0 ohms, which I think is correct as they're also part of the grounding path.
Side note: I'm also using alligator clips and I'm confident in all the connections with the multi-meter. This is my first build so I'm not too experienced with how else to troubleshoot this, so any help would be greatly appreciated! Thanks!
