I purchased a pristine MTH Triplex recently.  Owner hadn't run it for years and strongly suggested I replace the battery before powering it up. Good advice. I would like to replace the batteries with a BCR.  Then I opened it up and found this: 2 AA Ni-Cd 1.2v batteries. (So I assume it's a 3v system...) (Manual calls for a 1.5v rechargeable NiCad battery...???)

  They look to be original.   Is there a BCR or equivalent I can use as a substitute for these two batteries?  I know J & W produces a 3v BCR-2 but not sure if or how I could use it.

  Is there something else available or are my only options to cut the wires to the battery case and install a plug compatible with the J & W BCR-2, if that's OK or, just replace the two Ni-Cd's with two new rechargeable 1.2v 700mAh batteries?

Thanks.

Ed, ….hard to tell in your pics, but at first glance, it looks like your speaker is flaking apart buddy!!…..stop & investigate, take a close up pic if unsure, and post it up for a double check,…..a flaking speaker can destroy the audio portion of your board set,…..best be safe, then sorry!!

You are right Pat, that is a red flag!  Before you run that, I'd for SURE replace the speaker!

Thanks Pat!   Here's a pick...

Triplex Speaker

I noticed Peeling?"  It looks like what you described along the edges.  Is that what you meant?  Thanks again for spotting this.

Thanks for the info. I just ordered a speaker from DigiKey.  I'll pick up some batteries. i can't wait to see this beauty running....smoke from the tender, what a hoot!

Ed, I would install new 3V batteries first and make sure all is working first.  Also maybe replace the speaker as well........... If all works, I'd contact J&W, he may have a device to install the BCR... in this type of engine'...

Ted, that's now the plan.
