Thanks Mike Bellamy

It seems to be out of print .

I’ll keep trying !

I wish I could find this book!

Thanks . Yes I misstyped it!

It is only a motor and not a bogie. Please see photo.

I have just acquired one of these kits. It has a Tenshodo motor but in the box it says it contains a Ks HP2M motor which needs Romford 20 to 1 gears with a small bore gear wheel. Does anyone know where to get the suitable gears for the Tenshodo?

Good to see a happy ending

 

Your description on the decoder connections sounds correct to me

 

NMRA standards for decoder wiring to track

Red to right rail

Black to left rail

 

If it goes backwards when it should go forward then swap the Orange & Grey wires

I have determined that the drawbar connection was shorting. I have insulated it and things now run ok. I now have to figure out how to hard wire the decoder. Presumably all the black wires to the correct decider wire and all the red ones to the correct decoder wire, then orange and grey from the decoder to where the red or black wires originally connected to the contacts on the motor, omitting the capacitor? Thanks everyone .

When you did the conversion did you isolate the brush connections from the chassis 

 

Is it a ringfield motor. A class 91 I converted had a screw that holds the motor together & is the electrical connection between the brush holder to the chassis  

To isolate the brushes from the chassis this screw had to have an insulating  sleeved & an nylon washer used under the head  

 

Does this loco have a wired connection between the loco & tender or the removable type with a pin & contact fingers

 

If it is the latter these can get bent & cause a short

 

Did you connect the wires in the tender the correct way around

If the loco or tender are connected with incorrect polarity then when the loco & tender are on the track then you get a short 

A quick test for this is to put the loco & tender on the track with a sheet of paper under the loco wheels, run the loco & note the direction of travel

Next place the paper under the tender wheels & run the loco with the same controller setting & note the direction of travel

If the direction of travel is different then there is a wiring problem. Crossed wires in the loco or tender

 

If none of this helps then photos can be very helpful

Thanks for this. I will investigate. I have attached a photo. George

Could one side of the motor be live to the tender chassis and its pick ups?

Are there not supposed to be pick ups on the tender which connect to the motor? There are pick ups on the front and rear tender wheels. I am unclear about the whole thing!

I attempted to convert to DCC, but as it wouldn't work and buzzed, I took off the chip and resoldered the wires to the brush holders. Problem is that although the tender will run in its own, as soon as the loco driving wheels are placed on the track nothing will move. Ther continuity tester buzzes when I connect opposite driving wheels. Any ideas what I might have done? Sorry if this is not in the correct section.

I am interested in biographical stuff on well regarded modellers. I was also impressed by the Halland layout and much of Tony Wright's stuff.

Which boxes?

Please see photo attached

Does anyone know where I can source these boxes?
