Large Scale Central

Looking for all Bachmann Heisler experience folks

I’m looking for those with specific Heisler experience. I’ve been looking for one for awhile and finally picked one up. The PO has done a bunch of mods. Some I may keep and some won’t. Personally I prefer to keep them mostly original or easily able to return to original. For example, I happen to like the firebox flicker so I leave it. I know you can’t really see it much except when looking right at it, but I like it. It was removed and there is a piece of plastic covering it. He had an Airwire 900 in it which I won’t se since I am going all to RailPro. He cut out the large scale switch and replaced it with appears to be a charging jack. Which I don’t understand since there is another charging jack in the rear. I thought there might be a second battery in there but when I pull off the front, I don’t see any and can’t really tell where the wire go. It also appears he cut the wire going to the cab lights and I don’t see where they are wired to the Airwire, just left cut. I’m getting the feeling the factory guts are all gone. But I want to verify that.

So first question is after the cab roof/bunker is off, what is the easiest way to get the shell off? I studied the factory drawings and it’s hard to tel, if I have to take it totally apart or not.

I need to chase the cab light wires to figure out where exactly they are supposed to go. The red and black on one side AND the red and yellow on the other side are just cut at the base.

Pics to follow along with more questions.

Anyone tell me what this is? It has a heat sink or at least that is what it looks like to me.

Here is the Airwire 900 board that was in it. What’s it worth?

do not know what the Airwire board is worth as Airwire will not repair because they consider obsolete and will not repair boards in general unless you are the original purchaser. so if you have no way to test your best bet is to give to someone using Airwire, and have them test.


Obviously a Flux Capacitor for when you want to exceed the speed of sound.

And just discovered a broken front truck mount. It does run but I’ll have to take it totally apart and try to figure out if/how to repair the mount. It is right where it attaches to the frame. Should not have bought it now. Lots to fix.

to me sounds like a sound jack

Hello again Mickey. Do you have the Heisler’s wiring schematic ? I can supply one in PDF format, as before with the power trucks. Could you provide a more “open” shot to get an idea what surrounds the bits you are showing and to give a better idea of scale. I have a Heisler (arrived 2nd hand but unmollested). I have recently had that converted to battery/RC operation, using an ESU DCC card for sound and speed control. Max

I’ll try to get some pics and post. But what I have discovered so far is that the PO did a pretty radical set of mods, which is not uncommon for some folks. He converted an oil burning bunker into a coal, removed all the factory wiring, removed the flickering coal box including cutting off the screw bosses, cut out the factory NMRA/Off/LargeScale switch and cut out the area to install a battery charge port, installed a battery pack in the bunker and one in engine behind the firebox door (removed the weight) cut wires to the cab lights, relocated the rear light from roof to bunker, epoxied a speaker box, and more. So I have a lot of restoring to do. I bought a shell as a part because it comes with the wiring harness (which is gone), and a replacement firebox for a Climax (since it is at lease available, to get started getting it “back”. But I have a lot of work. Had I realized all of this, I would never have bought it. But that is what it’s like when you have to buy without physical inspection, unless it is “like new”.

Turns out it IS a charge port and a second battery in the firebox.
