Testing for continuity

Posted by Alan on 3rd September 2015 in 0n30, Alan's Railway |

Have made up all the jumper cables the other evening, the last remaining electrical job was to solder the dropper cables on the corner boards. These hadn’t been done because I wasn’t happy with the track alignment. However, with the first exhibition looming …

I’m still not happy with the alignment of the track, because it’s not centred exactly. However, to do it to my satisfaction, I need to invest in a Code 83 roller gauge¬†and construct a jig to ensure the accurate centring of the track at the ends of any board. That ain’t gonna happen before the Seaboard Southern exhibition, so it stays as is.

All that said, the boards were laid loosely on the floor and plugged but not bolted together. The connectors at the far end were plugged together as well, to create a ring main, and the connectivity tested. The resistance dropping from infinity proved that current was flowing the whole way round. Result!
