Lionmaster legacy Big Boy sound issue

Before you order anything, just take a look at the wiring under the heatshrink on the drawbar.  I've had a few of those break, I just cut off the heatshrink, solder the wire back on, and put on new heatshrink.  Check the other wiring inside as well.

John - you make a good point. When it stopped I noticed the wire to the truck - presumably an earth had broken and soldered that assuming all would be well - I never thought of checking under the heat shrink. I guess if something snagged the wiring it might have done it there as well. I will report back.

Thanks for your reply.

I've seen them break just from the movement of the drawbar.

Hi John,

You were right.

The wires hadn't broken under the insulation though it was further up where 3/4 wires join the two from the IR via a tiny circuit board. Looks like the shrink wrap got caught as the trailing truck or draw bar moved.

I don't have the soldering skills or a steady enough hand to attempt a re-solder so have ordered the assembly from Lionel that includes the circuit board already wired. It cost me $6 more but this is insignificant compared to postage as it  will be coming to me in England! 

Thanks again.

I had this problem the shrink tubing in the tether caused it so, I would check the shrink wrapping. (My vocabulary is horrible),Has to be the IR sensor in the Tether of the tender.

I'm glad you located it Mike, I figured it was probably a wire in that area.  The drawbar moving creates a dandy spot for problems.

Funny you should post this now. I have the same engine and it has been back at Lionel for a week now for the loss of some of the sounds. I wonder if I have the same issue?

That's a common trouble spot for sound on those, the wires on both the locomotive and the tender get movement and tend to break.
