MTH RK PRR S-2 Headlight Not Working

My guess maybe you bumped a connector or something for the headlight, LEDs usually last a long time....

That was my thought too on the life of an LED.  I'll open up the shell and check the connector.

Headlight work in reverse on the other end?

Press HDLT on the remote.

LED out, impossible.

I don't think PS2 had leds. I assume you have tried the headlight button. When you get the shell off, check for 5-6 volts.

Sorry for the redundancy. Sirt got in ahead of me.

LED's started on PS-3's

I took the shell off and disconnected and re-connected the headlight lead.  Checked headlight button several times.  Tried a feature reset.  Still a no go.  Yes, the back-up light on the tender works when in reverse.  

I did not know LEDs started with PS3.  Makes sense that maybe the headlight is burned out.   

Will a replacement LED work for the bad bulb?

You will need a 220 ohm resistor in series with the led.

I'm not saying that my solution will be your solution but I"ll chime in with it anyways.  2 months ago I too had a headlight that I could not get to come on.  Tried both a factory and feature with no positive results.  Took it to an authorized shop and they didn't know either so the service person called someone at MTH.

The MTH guy said to do a CONVENTIONAL FACTORY reset, and that worked.  Since then I've learned that a conventional reset is slightly different that a factory reset using DCS to do it.

It's worth a try I guess.
