Large / securing G scale structures outdoors
November 08, 2020, 11:51:07 AM
does anyone have suggestions for securing G scale structures outdoors, yet allow for easy removal for repairs or painting. The high winds we occasionally get here in Nevada raise heck with the scenic parts of the layout.

Bill, your idea worked, small led was all that was needed, light works forward motion, off running in reverse. I'm sure glad there are wiser heads around to help the less experienced. TRhank you so much have a great day.

thanks again Bill I'll see what I can come up with. I notice your bio says Roundhouse foreman.  I used to live in a small town in eastern Oregon, Huntington, they still have a large yard, and did have a roundhouse, unfortunately it was torn down before I moved there, though the locals tell me it was quite a sight. you must have some grand memories.Again thanks for your help.

Thank you Bill, the gears are a bit mashed, it might be hard to get an accurate count, and that wee hole in the center for mounting. of bigger concern would be the angle or skew of the gears the teeth are not cut at 90 degrees to the axle.thanks for your reply I'll see what I can do.

Sir you are a genius, that thought never crossed my mind. I will definitely try it out and let you know the results, love to keep this loco running as it should be, its a sweet machine, and fun to watch. Thank you so much.

Does anyone have a set of gears for the G scale Rail Truck ? they come in a cast metal housing. Bachmann doesn't have them available anymore, or do you know any after market items that would work. Thank you

Headlight not working on two truck Shay, measured voltage on rear lamp of 1.9V same when checked against front and rear lamp on three truck Shay., yet this one reads over 10 volts. Changed the Voltage regulating transistor on circuit board in the tender no change. Anyone have any ideas or where I can find a replacement circuit board. your help is appreciated.

Can anyone help me identify the Q7 and Q8 type of transistors on the PC board of the rail track, they are   the two closest to the back of the board, mine got scorched, I think the numbers may be A1300 and GB201 but I'm not sure. I also ran into the oddest problem with the motor, the motor would not run unless it was turned upside down, a brush or spring problem? Anyway I replaced the motor and everything seemed to run well until I assembled the truck now it wont run on the track, the motor runs, but nothing else. Any advise? Thanks in advance.

Bill, thank you for your help, I found the issue when I lifted the circuit board there was a run (or Lay) whichever you prefer that was burned open, I cut part of it off since it was flopping around and soldered in a jumper straight pin to pin, and it works. Thanks so much for your interest in helping a newbee like myself, it's greatly appreciated. Happy Railroading.   P.S. a wee bit of wire is a whole lot cheaper than a new circuit board.  The Scotsman.

Isolated  all three motors from the circuit board, and one at a time put power directly on the leads leaving the board to the motors, all three motors ran. I'm still thinking something on the circuit board is bad, anyone have any further ideas to isolate the problem?

Thanks to both of you, I do have the PDF but it's no help as to whats happening on the circuit board. The DC power from the track is reaching the board at all three sets of terminals identified for each gearbox, however it's not making it's way from there to the designated terminals to drive the motors. since it's affecting all three motors I'm thinking an open on the board somewhere or a short. I think my next step should be to isolated all three motors and see if the voltage reads differently at the board, and then one at a time throw voltage directly on the wiring leading to the motors and see what happens. I did try ramping up my Bridgewerks controller as you recommended Bill, but it had no affect. Anyway  thank you both for your kind assistance.

Large / G scale three truck Shay
October 20, 2016, 01:59:49 PM
I am working on a G scale three truck Shay. I have power from the rails to the small circuit board mounted on the rear of the cab, no voltage to  any of the motors measured at the circuit board. the front light, rear light and the wee firebox light all work. running on straight power no DCC. Does anyone have any ideas or know where I can find an actual schematic not a line drawing of wiring connections ? any help would be greatly appreciated. I don't know if these three motors can run independently or all have to work together for the machine to run.
