It may be stuck in its "disconnected" or its idle mode.  I can't recall what function button it's on... hopefully he still has the manual that will tell him what to try.

I’d contact BLI. They should be able to supply a drawing for the engine and even offer advice.

You could also apply 3 volts with a series set of batteries. Not enough to hurt the bulb.

Re: QSI Decoder Wiring Information

A friend of mine reported the same situation with his BLI, B&O F7B engine which had a QSI Quantum decoder. Looking through the manual I missed the comment about the motor going into stand bye.
 
I noted on another list to which I am a member someone saying they had the similar problem a while back. The solution noted on this other list was to press the F6 button twice quickly.
 
I placed the B&O engine on my test layout, pressed the F6 button twice quickly, the engine jerked, and the motor would again function as it should.
 
A close review of the QSI decoder manual indicated that pressing twice the F6 button quickly flipped them motor control on and off. If on the motor control would turn off and if off the motor control would turn back on.
 
You might want to try the above. If just may cure the problem.

Re: QSI Decoder Wiring Information

Wil Davis
 

Thanks for the suggestions.  He has the abbreviated manual that came with the engine, but it offered no help.  I will try F6. 

After I posted my question, being impatient, I decided to try applying power to a couple of the pins to see what happened and found out that in addition to track power being on the outside pins, the next two were motor power as it ran across my workbench.  I next connected to the center two and verified that they powered the headlight, just before I got over zealous and burned it out.  I was really upset, but found out the if I remove the smoke box front the headlight is on a plug so it's a relatively simple task to replace the bulb.

Thanks for the suggestions I will report back if I can revive it with F6.

Wil,

The QSI decoder manual for steam locos is online and downloadable.  Just Google "QSI decoder manual" and it's among the first entries.

Thanks for the recommendation to try F6. I selected it 4 times and the decoder now works normally. I really appreciate the tip.

Wil,

There's a way to disable this 'feature' via CVs

For steam, change the CVs in order listed below
CV49=11
CV50=0
CV53=215

For diesel, change the CVs in order listed below
CV49=11
CV50=1
CV53=12

Read back and write down those CVs before changing them in case there's a quirk in your decoder; can never be too safe...

Should only take 2 presses of F6 to return from "disconnect" mode. You do NOT have to press them quickly, but two F6 within one second is fine.

By the way, pressing F9 twice is what puts it into disconnect, and two more F9 should go into idle down, and two more should initiate the shutdown sequence.

Controlling power (0n/Off) in Staging Yard Tracks

Bob Miller
 

I have two 8-track staging yards on my layout, one at each of the point to point mainline of about 100 feet in length. Each staging yard is its own power block.

I would like to be able to turn the power on each staging track on and off as needed and am looking for suggestions on the best way to wire them.

Controlling power (0n/Off) in Staging Yard Tracks

Bob Miller
 

I have two 8 track staging yards at either end of my point to point layout. The main line run between the 2 yards is approximately 90 to 100 feet. Each staging yard is its own block and the main line is dividing into 6 blocks.

Question 1: Is it advisable to wire each track in staging yards so that power can be switched on and off, e.g. to permit arrival or departure of train, but eliminate the electrical draw while the track is empty or a train has completed its run.

Question 2: If this approach is advisable, what is the best way to wire the tracks? and could SPST toggles be used?

Re: Controlling power (0n/Off) in Staging Yard Tracks

george hohon3
 

I have basically have the same set-up and wanted to have the same control on each of the tracks.  I am very happy with my decision to use a multiple position rotary switch for this.  I have 12 tracks in two staging areas and use two 12 position switches for on/off power control in each area.  Why 12 position switches?  Each rotary switch actually controls 6 different tracks and I only use every other switch position for power.  That way, I'm only one click away from an "off" position.

One staging yard is low enough so I can actually see a power indicating LEDs place between the rails.  On the upper shelf, the power indicating LEDs were placed on a "control board" for viewing.  I have photos if you'd like to see them.

A side benefit of the rotary switches is less clutter on the fascia.  Two rotary switches verses 12 toggle switches.

Bob, for every track (or group of tracks), isolate one rail on both ends of the track you want to control; insert a SPST switch in series with the isolated track(s) and the proper  bus leg for that rail.

Bob,

We have an 8-track staging yard, and simply built a panel with 8 DPDT switches and brought a buss from the switches that runs under each track to provide connection to drops.  An LED installed on the switch illuminates when the track is powered.

I’ve seen it done with both toggles and rotatory switches. I used power routing switches on my 4 track staging, but one track is always powered.

Advisable? Yes. At least add the isolating gaps to do so. A toggle switch per track is the easy way. Most rotary switches don't have the amp rating for track power and may become unreliable. 
Necessary? Maybe. DCC locos (even ones with sound) don't really consume that much track power when idle. But lighted passenger cars can/do. Turnning power off makes the sometimes annoying sound go off and positively prevents any unwanted/mistaken locomotion.

You can find almost any amp rating you need for a rotary switch at any good electronics parts store.  Mine have been in service for over ten years and they have been perfectly reliable in all those years.

More than you may want to know but the message is that the switching capacity of a simple rotary may be only 0.25 or 0.5 amps, but once closed the contacts can take several amps.  Might be a slight problem with high inrush current sound and /or lights when selecting a track.
