Working on the On30 2-6-0. 

Got the oil bunker almost done...waiting for a filler hatch. 

Trying to figure out how to isolate the motor. 

Waiting for the Genie to show up in the mail. 

Plenty of room in the tender for installation.

To isolate the motor, you need to take it out of the chassis,
then cut off the brass strips that run under the brushes.
Leave a little "soldering room" on them.

Solder the motor leads to what's left of the brass strips and then re-install the motor,
with a bit of electrical tape stuck between the bottom of the motor and the metal frame.
Then the motor should be isolated.

I am interested in this since it is a sound board/receiver.

I know that it should work on battery power,
and since it can handle DCC track voltages and a DC power pack,
then it can certainly handle a 7.4 or 11.1 volt Li-Po battery.

I am watching this.
Just be careful and it should work "as advertised".

Woodie

Just trying to figure out how to get the motor out,

without taking everything else apart.


Found an exploded view of the 2-6-0,

but it doesn't help much.

Well, there are 1 or 2 small screws under the "board" in front of the motor,
they need to be taken out,
and then there's a Phillips screw behind the motor/worm to be taken out.

Then you should be able to lift the metal weight and motor out.

You do need to take stuff apart when you're modifying things.
It's also a great education-experience.
Tell us how it goes.

Woodie

*** the board is to bring track/wheel pickup to the motor.
I don't think you'll need that anyway!***

The motor is out!

There is a plastic retainer around the motor. 
Once I pried that off the motor lifts out.

I placed some .13mm styrene in where the motor sits,
to isolate it from the frame.

According to my multi-meter, there is no continuity,
so the motor should be isolated. 
Right?

It would be nice if I knew what I was doing.

Sorry that I had some bad info for you...
It's been a while since I messed with one of the 2-6-0's.

Don't get old, your memory goes...
What?...

Yep.  It's now isolated.

Woodie

Woodie,

No harm done. 
At least I was able to get the motor out.


Was thinking of powering the headlight directly from the battery,
to remind me whether the engine was turned on or not.

I just couldn't wait.


I unplugged the receiver from #20 (the little diesel critter),

soldered on a connector to the motor terminals of the 2-6-0,

and fired it up. 


It works!


This is neat.

Woodie,

I got my mits on one of these Loco Genies.

I will bring it over for your inspection soon.

Wow Phil...as we used to say..."Groovy!"
I am interested in it since it features steam sound and is BPRC.

After messing with DCC/Tsunami operations,
I am ready to go back to pulling the loco across the floor with a string!

I will still have silent running on my layout,
but the show circuit requires choo choo & ding ding...and loud, I might add.

Now back to the thread at hand.

Woodie
