Changing CV29 is a lot easier than rewiring. Plus it also makes the lighting work correctly with locomotion direction. I do this all the time with any ABA consist.

How do you know it's misswired? And why take a chance on voiding the warranty by mucking around inside a brand new locomotive?

If you are going to run two 'A' units tail-to-tail, you're saying open up one of the locomotives and change the wiring? Then open it up again when you break the consist, and do more soldering? 

I don't recall the OP saying that the loco was new, but no matter. If the loco runs in reverse when it is supposed to be running forward, the first thing to check is the value of CV29. If that indicates that the loco is programmed to run forward, then the thing to do is to flip the two motor wires on the board.

If you are going to run two A units tail-to-tail, as in your example, first make sure that both units run forward when you apply the throttle for forward direction. If so, then program CV29 in reverse by add 1 to the value for the trailing loco. That is a function of CV29. Or better yet, with the PH-Pro, just use Advanced Consisting and the system will do it automatically for you.

ndbprr is correct in refering to "marker lights" as BLI's only option is red or off using function F7 as noted in my post above. Unfortunately, they are not direction-oriented as F0F and F0R are.

By the time the 1950's came around, CTC and ATC made obsolete any need for classification lights.

The PRR Baldwin BF-16s were fitted with red lenses and had no use as classification lights.

Scroll to page 17 for a prototypical example.

Have Fun! Ed

Noticed the marker lights on the shark were on when going forward.

What do you mean by this?  If the color of those lights are white or green, they would really be class lights and should be on (or off completely) while going forward.

It may be the easier way, but it is not the better way. In fact, it is not the correct way. CV29 did not include bit 0 for the purpose of correcting a miswiring issue.

And changing the motor wiring will not have the head lights come on, on the trailing engine, when the consist is running in reverse.

Changing the CV29 value by 1 is one way to change direction, but the better way is to flip the two motor wires.

Thank you for the chart
034 it was. E verything I had programmed up to that point was 0 or 1
Had the right cv but assumed 0

I don't have my Sharknose manual in front of me but If I recall correctly F7 turns on or off the red markers. They are not direction triggered so they're either on or off. Number boards are continuously lit.

The Centipede light is supposed to be a cab light and should turn off once you are above 3 mph. I'll see if I can find information about disabling it.

*I'll check the functions for the Shark and update this when I get to the layout later tonight*

Good Luck, Ed

The Power Pro will read CV settings if you are using a program track. You want to look at CV29. Then check here. Scroll down to page 34. There you will see what to change CV29 to depending on what is in CV29. [ If your decoder has 35 in CV29, you would need to program in 34 into CV29 to change direction ]

I would get the locomotives running in the right direction before doing any thing else. A lot of times that will fix some lighting problems.

Sorry, don't know anything about your lighting.

 

PS: CV29 does the same thing in all decoders.

Started over from scratch and have control and all functions backm very relieved
However have two issue o can not resolve. The shark goes forward when the procab say's reverse. The one centipede goes forward when it say's forward and the other one is factory set to run backwards. The shark also has the red marker lights on when the headlight is on in the same direction. Any way to turn off the marker lights? The centipede has a very annoying white led behind the cab that blinks inside like a mars light in the engine compartment
Any way to disable that? Thanks for your help.

 Reset should be done with programming on the main, although if you are no unsure of what address it might be, you could be out of luck. If NCE supports it, you cna do POM to address 0, that's a broadcast, so take all your other locos off the tracks first or they will be programmed as well.

 Or just try to give it an addresson the program track, it won;t care what the old address is, and it will fix CV29 (which is what you probably messed up since that's what you change to set the direction of travel).

 The NCE reset menu option is for NCE decoders only, it doesn't 'reset' anything but programs a bunch of CVs to known values. Some of those do not apply to decoders other than NCE ones, so you shouldn't use that for non-NCE decoders.

No. So after I program it on the program track power it up on the track power. Will try when I get home
Thanks.

When you did the reset, did you cycle power to the track? The headlight should flash a number of times and the loco respond to address 3 for a successful reset.

Our club has the NCE 5 amp system but we only did resets from the program track for obvious reasons.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.

Received my NCE power pro 5 amp radio system yesterday. Hooked it up to a length of flex track and programmed a BLI shark and centipede. Everything worked fine. Noticed the marker lights on the shark were on when going forward. Can not find any way to turn them off then it dawns on me that the direction is reversed. Try to find the cv to change it and somehow have given it a lobotomy. Now the marker lights and number boards come on with power and nothing else works. How do I regain control? Tried the nce restore and the bli change cv8 to 8 with no change. New to this and stumped. Thank you.
