TAS SMOKE & CONTROL BOARD

This is just a guess but that doesn’t look like a TAS smoke unit. The small board your are asking about may be the TAS-1022 Puff N Chuff upgrade board. You can google it and find wiring instructions.

Rod you cannot see it in my photos but under the smoke unit bracket Train America Studio is molded into the casting.  Also the control board has a dedicated harness that matches up with the smoke unit.  I am fairly sure the output of the control board plugs directly into a TAS TMCC board.  Just not sure without a doubt.  I am also fairly sure that the two wires coming out of the right side on the control board are bottom = chassis ground and one wire above is center rail. I would however like to make sure before I fry both smoke unit control board and a TAS cruise board.  Thanks for the tip on googling Puff N Chuff         j

Thanks  John ! Always glad to have add a new guide to the collection but it is different than my board           j

No matter what board it is I would junk it and gets Johns supper chuffed board.  Just my two cents

The loco it's going in is not worth John's Super chuffer board.          j

Looks like a TAS unit from an older Atlas diesel. I've got a couple in my parts storage. Constant smoke output. I don't believe it can be set up for puffing operation.

Thanks ! That is good info.   I can make a puffing circuit for it and just depend on the board for 3v. I was hoping that it was a version of the Puff-n- chuff.          j

I have several of them as well, and they're from 3rd Rail F3's.  I also have the smoke units with the F3 manifold on them.

Thanks John, now that I know this is a diesel board  plan is to install this one in a Williams PRR L1 Mikado that I have been adding detail a piece here and a piece there for two years. It's looking pretty good but has that da-mn 42:1 gearbox. Since that board is for a diesel with no provision for chuffs I will use it as a power supply and switch the motor with an IR optical switch.  Though I have smaller chinese power supplies that can do the job and may opt to save that TAS board for something like powering LEDs.  I plan run the loco with a TAS SAW board a while to see if it might be worthy of full ERR electronics. It has a Mabuchi 385 in it right this moment and will pull 25 cars at a scale 60smph though I would be happier with 50smph and slightly cooler windings in the motor. The TAS SAW board will not drive a coreless motor however the non cruise ERR boards will and If I go full ERR I will install a Maxon coreless in it. I just want to make sure the locos chassis does not have any bugs, low speed binding etc before I go to the expense of ERR. Some of these Samhongsa locos had loose wheel journals and would run smooth at anything above a crawl but the slop in the journals would cause a slight bind when starting or running very slow. The cure is to shim the sides of the journals. My experience is the rear axle is most likely to need the shims. Any way these Samhongsa loco running characteristics are unpredictable and I will test it for a while before I spend too much $.          j
