The other day I noticed my MTH power lockon smelled like it was burning, so I checked the track voltage from the TIU and it was at 22.xx something. I saw on the MTH 750 brick the voltage was 24 - wow. Then I checked the other 750 brick and it was 22. Finally I checked a 1000 brick and it was 18. Sooo, I'm thinking I shouldn't use the 24v with the TIU, but what about the 22 or 18v? Can those safely be used? Can I use the 24v one with a manual dial power module?
