To day I had brought a "Rollenprüfstand" 78151, so now we can service a Big Boy, but we do not one, as it can not get around in our helix's ....

Along with it was also a Measurement Device 78111 + meter on 78151, but unfortunately the wires are broken off on the small print. The wires are green / blue / black, and they can be soldered carefully again on again,

But is there anyone who knows the order?

And thank you Ross for your help from as far one can come in this world.
I will soon heat up the solderiron and see if the print still is alive !

It worked.

I put in some plugs on each of the 3 wires for protection of the soldering.

BUT there are other problems ..........

First / Something slides, because the measurement varies at constant speed of the locomotives and too little speed is displayed, so I shall see what you Ross are writing about that.

Secondly / There is no current in the ball bearings and terefore I can't have a tank locomotive or a diesel pulling on both bogies at 78151.
Is this normal ?

More from Denmark ......

I've come further into the rail and have found that my friend - who I can't "ask" anymore - has made two holes in the rail, and with the drilling i one hole, he had hit the red wire to the center rail in roll area.

It explain why there is no power where the rollers are.

So now only problem the signal to meter.
