Issue with Lionel NKP765 Back up Light

This was a defect with the legacy berk tenders, the led for the backup light needs a resistor in the line. Mine went out in my PM berk shortly after I got it. I emailed Lionel customer service and they sent me a replacement which had a resistor in the line the original did not have. Its been about 2 years now and its been fine ever since.

Thanks Rick, I will give them a call.

My Pere Marquette tender light went blink crazy on arrival. I contacted Lionel and they sent me a replacement light. After some time that one started blinking. My Polar Express tender did the same thing. I contacted Lionel about both and was told there were no more replacement lights/boards for these, but that they could give me an RA# to send them in for repair. Well, I'd rather have no tender light then to be without them, so I took the lights out...for now.

I believe there may have been a post on this a while ago, but cannot seem to find it. I have a Lionel NKP 765 where the back up light does not function. It is the new style with the small board wired to the light in the tender. It has been replace and seems to have failed again. Any insight would be appreciated. Thanks.

Exact same problem here

If Lionel is out of replacements maybe some of the knowledgeable folks here or on the tmcc/legacy forum could direct someone to an appropriate aftermarket replacement, I would think one could cut the wires and attach them to a new bulb.

I had an M1b with the same problem, mailed it off to Lionel and they wired in a capacitor instead! Now the marker lights dim to off after 30 seconds....

How do I get a replacement mailed to the house?

Good information!

mtnhi7.....isn't there a diode in the circuit? Or a resistor? I had thought the original reason the LED burned out was that one of these components was inadvertently left out of the circuit.

With the report of Lionel no longer able to provide replacements, can someone draw up a circuit for these back up light?

Steve

Steve, I took the tender apart and looked at the pc board and LED. The pc board in my tender doesn't have a resistor. I just went to RS and looked for a white LED. I don't recall what the voltage is that feeds the light. Maybe ask Lionel? Likely 3 to 5 volts.
