@Hancock52 posted:That’s phenomenal (not to say excessive) output, particularly from a smoke unit that has a 90 degree bend between it and the stacks. But of course it’s newly wicked and refilled with fluid, and looks to be operating on track voltage, so the volume of smoke will be at max.
I’m guessing that you didn’t drill a separate refill opening above the smoke unit and so the body shell will have to come off to recharge fluid as well as replace the wicking.
More importantly, I’m not sure which TMCC boards you are using if they are not ERR but most have a smoke power option that enables you to switch power on and off from the remote. Or is that not an option here? You mention they are older boards and I vaguely remember some made for diesels did not have smoke controls.
P.S. Excellent work on the brass tubing! I have resorted to using solvent- and heat-proof plastic tubing for the one thing I have done that is similar to this. That has three elbow joints in it, which reduces the pressure at which the smoke exits.
@Hancock52 You are correct I wired the smoke unit direct to the power pick ups on the chassis. I mounted the body of the smoke unit lower inside the shell than the exhaust manifold. The black tubing goes down hill into the smoke unit so I wouldn't have to take the shell apart to fill with new fluid.
If this TMCC board has a designated wiring terminal for the smoke output that would be great. My hesitation would be to draw too many amps through a wrong terminal if it was only rated for a small LED. I don't want to cook this working board.
Do you know where I can find a drawing of the output terminals for this 21 year old circuit board? The board originally came out of my K-Line Union Pacific E8 "949" when it was being upgraded to ERR. The set of locomotives was made in 2000 and the K-Line O-Scale Diesel locomotives part number was K-28901S. I'm not sure if these photos will tell you anything but here's a couple shots of the stickers on the TMCC board when it was being removed.
