Light hook ups on a Lionel ERR upgrade

The ERR package has two lighting outputs, forward and reverse.

In command mode, the lighting outputs put out half-wave track power, so what you see is pulsating DC.  The polarity of the lighting outputs is negative in respect to frame ground.

I'm sure things are getting warm running on track power, those are 14V bulbs in the conventional models!

How about a specific product number?  I looked at the conventional H16-44, 6-38438, and I don't see any complete wiring harnesses, so it's hard to know what you have.

Besides the model, how about some pictures of what the existing lighting harness/boards look like?

6-18385

I can prepare some pics over the weekend.  There are four wires on the harness.  Red, black and 2 purple.  The red is power, the black is cab lights, the inside purple is backup and the outside purple is forward.  Should I not just be able to run these to the ERR board somehow?

Thanks again Gun!

Lionel parts doesn't show anything but the wiring harness, so it's hard to tell where it goes.  The DREU reversing unit only has two outputs for lighting, so you should be able to use the same logic for the ERR rig.

If I know what each wire does, red (power) black (cab light) the 2 purples are for the headlights, where should these wires be running to on the ERR board?

Does this engine have LED's or incandescent bulbs?  The reason I ask is that the ERR outputs are negative in respect to frame ground, and if they're using LED's and assuming the full-wave AC from the DREU reverse board, you may have to do some adjustment.  Again, they don't show the light breakdown for this engine in the parts, so I have no idea what the lighting board has on it.

Remember those pictures I asked for?

Logically, the purple wires would go to the two light outputs on the CC, but I'm wondering about the polarity issue.   Since you have a smoke unit that will presumably be using the feature output, you'll have to ad-lib the cab light.  Put a diode in series with it and connect it to track power.  The diode is to cut the voltage down so you won't cook the bulbs.
