B&O EM-1 decoder install (cont)
This install has not gone well.
I was testing some speakers so I was going to use some alligator clips but, while powering up the decoder, the speaker wires must have touched each other or the tender frame and hosed up the decoder. Put a new one in and all's 'good'.
Will be sending the bad one back for repair.
Initially, I thought I, also, burned out the three LED's in the tender but the 'light' function wasn't on.
Initially, I used F2 (the violet wire) to turn on/off the red tender lights but that button only allowed the LED's to light when the button was held down.
I switched to the F3 (brown wire) and that worked to control those red lights.
The tender headlight connected to the yellow wire, default for 'on' when engine is in reverse.
After all the wires were 'shoved' into the tender....
some foam was used to protect the wires.
More troubles in 'river city'.
To protect the thin LED wires to the classification lights, I ran some 1/16" diameter heat shrink tubing along the inside of the boiler. Some long, easy to see inside the boiler, yellow wire was soldered to the ends of the LED wires and routed through the tubing: not an easy task since the front smoke box doesn't come off!
The LED's worked great until I tested for contact against the boiler and blew both of them. I think I pulled the thin insulation off the LED leads when pulling them through the small hole in the boiler which made contact with the brass boiler.
I need to use the volt meter to test for shorts instead of trying to quickly touch the boiler to the LED leads: not fast enough (idiot)!
Start over: new LED's glued into the classification lights; let that dry for awhile.
The yellow wire was soldered back onto the old LED leads so, at least, it will be easy to re-route the wires.
