GN C-1 0-8-0 Tenshodo decoder install.

No sound installed in the switchers; just using TCS 1485 KAM5 with keep alive.

Kept the original open frame motor but had to insulate it from the engine frame.

Some electrical tape on the motor, a piece of red heat shrink tubing on the screw and a kadee washer next to the nut.

The slot on the brass mounting plate also had to be enlarged.

GN C-1 0-8-0 #810 01

Not enough room in the engine so the decoder went into the tender.

No lights installed so only needed to make a 3 prong connector: red for ground, orange/gray for motor.  

Without lights, pretty fast install.  Only needed to solder the black wire to the tender shell.

GN C-1 0-8-0 #810 02

Had to change the original #815 to #810 since the switcher at St Paul already owned that number.  Some solvaset on a q-tip and some aggressive rubbing removed the #5 without damaging the paint.  The #0 came from an old used set of champs GN decals.

While I was doing that, also added the C-1 nomenclature below the engine number.

Sometimes you get lucky:

I lucked out in that the top of the open frame motor touched the boiler, threw the CB but didn't 'smoke' the decoder.  Some extra electrical tape on all sides of the open frame motor fixed that. 

This engine is assigned to the ore dock.
