Zimo decoder and 73 Class update

The only thing I got around to over the weekend was finally doing something about the replacement Zimo decoder that arrived two weeks beforehand!

After Club Saturday, I had some spare time in the afternoon. So I decided to open up the shed and test out the decoder. So I wired it up just to two of the pickups and the motor wires. And then I applied power. At this point with the first Zimo decoder, things went up in smoke! However on this occasion, we had movement with smoke from the decoder. Hoorah! However the dodgy factory wiring on the 73 was such that it went the opposite way to what I had assumed should have been the correct wiring. No big problem, just reverse the gray and orange wires from the decoder. I was happy with things at that point and left it at that for the day.

Sunday morning a thought transpired of why not wire up the little speaker to see how the thing sounds. The only time I got to do that was Sunday night between storms. After selecting the diesel option CV I applied the Sound On button (F8). And she cranked up. The speaker had some static going through it so I will have to investigate that. Could be a dodgy solder joint, or volume adjustment, or something else. But we have sound. Next step those LEDs!
