Is there a diagram or a listing of the uses for the solderless connectors on the PC board.

My engine has H850X-PBC01 and I would love to connect a sound decoder. It certainly looks like I should be able to use some of the solderless coneectors.

Are the ones marked 'R' and 'L' for the right and left pickup? What are the LED + and - ones for?

Thanks,

Bill Schickling

My son and I added DCC to our layout last year abd love it. We could only afford DCC equiped locomotives without sound. But since have added a few DCC with Sound loco and it has totally changed how much we use the layout. It is so much more fun with the sound.

I have seen an MRC addon sound decoder but it looks like it requires soldering. Not a skill I currently have. My son really doesn;t want me to ruin the trains.

Any drop in or replacement decoders I can use ?

Thanks.

Barry,

Thanks for the reply.  We got a bulb at Radio Shack and spliced the wires from the old bulb. The new wires were small enough to fit in the slot. The new bulb works great.

How easy is it to convert the original drive to your upgraded one?

While I had the train on the dining room table I took the bottom off and greased up the gears and put some dielectric grease on the cam that provides the chuffing sound. The train still runs kind of rough. It seems like an electrical pick up problem. I cleaned the wheels with rubbing alcohol to take the track grime off too.

Are there other service points or is it just better to convert?  We have had our Royal Blue for 10 or 12 yeas and it has always ran great. It still smokes like crazy and we bought the two other cars that didn;t come with the original set. So we have made the Royal Blue a proper train now.

Ok. I did some reading on the forum and came across a link to some tips that led me to a page on how to convert the headlight to an LED. That looks like it involves more than I bargined for.

I found that the headlight just pulls up from the body of the train.

Once we had the headlight off we saw that the bulb had burned out and just needs to be replaced.

Does anyone know what the replacement bulb would be?

My son and I have enjoyed our Big Hauler for many years. The head light has been out for so long we can't remember when it ever worked.

I don't believe the light on the tender ever lit.

Can anyone tell me what is involved with fixing the headlight. The lens on the front of the headlight appears to be glued on.

Thanks for any help.
