Control Panels – Part X

Written By: Alan - Apr• 24•17

Progress! 9 down, 7 to go.

 

Allow me to share a painful lesson learned – check that all LEDs are in the correct position before assembling a panel. It happened on the Brittain Yard West panel. After several hours work the panel was all soldered together and placed in its enclosure. As I do with all of them, I began testing to verify the wiring was correct. Halfway through testing, I insert the connector expecting a green LED at turnout #40 only to see the yellow come on. So I reverse the pins and the green LED lights. Maybe I accidentally reversed the wires on the connector board. Then I realize the yellow is way too dim and the green way too bright. Ug. The only possible explanation is the LEDs are reversed in their holes. Sure enough that was the problem.

I had to un-solder every wire then completely disassemble the panel face just to switch two LEDs around. Then re-solder every connection a second time. Yeah, I was very mad at myself for not checking first. A whole weekend down the drain. Won’t make that mistake again.

Other than that one misfortune the panel construction is proceeding nicely. Slowly but moving along. This has been my view for the past several weeks and likely several more.

The iron is hot. Gotta go.
