The problem is that the track is thinly tin plated... you should develop a strategy for treating the rails to stop rust... if you are track powered, perhaps one of the tried and true "coatings" to slow down rusting...

Yes and no.

Many people have experienced this.

No, you did not get a lemon, they break... not unusual... (guess this might not be allowed to post)

did you already purchase the switch manchine? then you can try measuring to get an approximate value...

On the face of it, I would say it would draw more than 40 ma

Greg

yeah, I do the same!

I see I need to add more to the k27 pages... I'll add some more... looks like the documenting of the motherboard needs doing...

TOC is sending me a motherboard, and I'll document the solder pads for hardwiring, and possibly installing a bank of screw terminals like they should have.

Greg

Fan was to cool the motor...

Nothing to do with chuff, and sometimes it interferes with smoke, sucking the smoke back into the boiler... in that case, reverse the fan (physically)

I don't think the K27 has a fan in the tender, but if you look at the schematic on my site, you will see there was a provision for a second fan on the circuit board.

That fan would be to help cool the decoder.

Greg

Bill, I have updated the version list to include the newer plug and play loco... I realize your list is focused on the drivetrain, but lots of questions pouring in on adding decoders.

If you have a chance, would you check my page and see if I made mistakes or omissions?

As I responded by email... no reverse switch... your "new" loco is not new, and it never had the reversing switch.

Furthermore, after a long conversation with a friend, you would really have to do a lot of disassembly of the trucks to re-wire to reverse them, since the track pickups are wired directly to the motors internally.

Can you reverse your other loco?

Greg

36 ton shay please, many of them out there, but they are different, especially wiring and circuit boards

Interesting... preventing oxidation means there is a coating of some type on the rail. Have you noticed any reduction in electrical pickup?

swiffer... for cleaning...

if you are removing oxidation, something different...

if you are removing rust, something different.

here's about 20 years of experience:

Ive got the aristo and the bachmann ones... if no one else measures theirs, I'll measure one.

you are missing the hatch where the 9v battery goes? The most commonly broken part..

there may be people printing these... I'm checking and will report back if I find it.

(I assume you went on the bachmann parts site and looked already)

Greg

Perhaps also download the parts/exploded diagrams from Bachmann to see how things go together, you would see the hubcaps and screws

If you find the others, email me, and I will archive them..

I guess I need a place for people to download files....

Greg

I have it, email me... greg "at" elmassian "dot" com
