item 6-11449 4005 big boy vision line the original with dual smoke whistle steam and blowdown with dual speakers in engine and tender has eaten a fourth rcmc board no smoke or blow down the low noise it makes ceases after 30 seconds and no commands from cab 2 are acknowledged after that all other engines work fine and as a heads up to all the only rcmc still available is for the 4004 so this according to lionel will have different talk etc I could have sworn last time they were able to program these for whatever engine number you had or am I mistaken? I have to ask those more electronic minded is there a fuse or? that I can install somewhere that will blow first before takinhg out this rcmc board thanks for any clarity on this

Might want to look into installing a transient voltage suppressor in the loco if you haven't already. Costs next to nothing except the time and effort to install.

One of the best ways to help protect your engine’s electronics is as had been said installing transient voltage Supressors. The can easily be installed on all the outputs of your transformers and if you use other devices like ASC’s or other controllers Ike TPC’s install them on both the inputs and outputs.
You can purchase them from Newarks and other electronic suppliers they cost about $1.00 each.
I would recommend the following TVS: 1.5KE33CA
It will protect you from any voltage spike above 33 volts and safely direct it to ground. No need to install them in engines unless you run your engines somewhere other than your layout.

Don't take no for an answer. Agreed, they have a pile of RCMC boards in stock and they program them for the specific engine you ordered it for. I've never had a RCMC blow up and only have heard of them going bad if the cannon motor shorts. So what's going on in your engine/layout? 
In regards to transorbs, Nice cheap, and they work but they are made to self destruct to protect if there's a really bad spike and you won't know if they are bad. Spend the money to protect your 2,000 buck engines and go with these. I have a couple of videos on my channel on these.

I’ve installed TVS’s on my layouts for over 20 years and never had a board failure (knock on wood). Circuit breakers are fine but a TVS with the right configuration will react over many times faster than any circuit breaker. They may be prone to failure but I’ve not experienced that thus far.
If you are really concerned you can construct a simple device to detect a spike using instructions in a document prepared by an electronic engineer and published by the DC Highrailers.

I would definitely check to see where the short is on the layout. Other wise you are going to be replacing another.
What kind of track are you using?

well now my error as i assumed I had correct sku for my big boy and I did not so customer service will get with shipping and stop the current order from shipping and reorder correct part number for my 4005 so thanks for the heads up on the programming apparently either they program them when ordered or some are ready to go

What kind of track are you using? no short that i know of this happened at startup engine sitting idle no wheels or errant strand of wire on track only thing is this one the smoke fluid i added to blow down for whatever reason went all over the rcmc board so am thinking a fluid caused short? they really put that board in a bad spot I've been using combo gargraves and ross track for 20 some years now

What's your power to the layout setup?

What's your power to the layout setup? transformer to toggle switch from there to mth tiu from tiu out to original lionel bpc out of that to 4 different isolated track sections the main transformer for both mainlines is a max transformer that a HO person created for o gauge use it weighs in at 33 lbs it has both volt and amp meters is as old as the layout and narry a hiccup back in the day was around$800 originally sold by davis trains
