UP 4-6-6-4 challenger decoder install (cont).
Normally, after installing the TCS 1517 decoder, I use decoderpro to test that all is good so I don't 'blow' a decoder but I've been getting 302 and 306 errors. I think I've got the wrong com port but will have to do some more checking.
Fortunately, all the wires were connected correctly and all's working. I had to use the throttle to load in the address on the mainline, insuring all other engines are 'off line'. The engine got the usual treatment: 8 pin connector between engine and tender, 4 pin connector between drivers and boiler, 2 pin connector between boiler and driver engine mounted headlight.
Sound and all 13 LED's working (headlight is sitting on the drivers). Adjusted the chuff rate to get 4 per revolution: this is always too high.
The original weight was pretty wimpy with about a 3/4" square so a new one was created. Some 1/16" thick lead 3"X9" rolled into a rod.
Inserted from the front.
The existing two holes were used to drill into the lead and use two phillip head screws to secure the lead weight. Also, had to drill a hole for the front drivers support. The spring inside was replaced with a stronger spring to support the additional boiler lead weight.
I put the two sets of driver engines on the boiler and tested the running characteristics and it was barely moving: turns out I had to cut some of the boiler to make room for the front engine's universal shaft.
The universal is white but I put some grease inside and some tape around it to insure it is quiet.
The shaft now has enough room to clear the boiler.
MMM; need to clean the lens, again!
Final assembly.
Detailed the cab with some white and red paint.
All lights working.
MMM: need to put some numbers on that front plate!
Still got one up on the nice stuff that MTH and BLI haven't done, yet, with their engines: running board lights.
Don't remember if they've adding firebox glow yet!
Some detailing on the boiler. Painted the insides of the smoke stacks, hand rails and piping. Red for knobs and brass for whistle and bell.
Pop valves painted.
Red on the grate shaker wheels.
Tender with back up head lights on...
and off.
A big engine but not compared to the C&O M-1 steam turbine!
Next is the road test pulling some freight on the mainline.
