Picked this up at the local train show yesterday. This is my first mth engine. It only has a whistle, can this be upgraded to have chuffing sounds? Is this only able to be run conventionally? Currently I have a z4000 and Lionel tmcc. The smoke unit doesn’t seem to be operating properly, can anyone help me out with a part number to replace it. Any information on this engine will help, thanks!

When I opened the tender I did not see a battery in there.
Did you see an electronic circuit board? Was there a harness for a battery?
here is a copy of the engine diagrams item 9 is the battery in the tender!

Might want to take a picture of the insides, it may have been gutted and replaced with a simple electronic e-unit 
Here are a few photos of the tender
Is there anyway to test this smoke unit?

Since you have it out, you can remove the four black screws on the top where the fluid goes in. Then, check that the wicking is not burnt and hard. If this has been stored awhile, the wick will need a lot of smoke fluid to get started. The manual says 25 drops and then wait 15 minutes. Those need to be generous drops too. The wick should be tucked along the length of the heating element in the smoke fluid chamber too.

is there a way to check the fan while it’s in this state?
There is no battery, on the box it says accepts plug in Protosound systems.

No. You need it connected to the controller circuit in the tender. You should be able to here the fan turn off and on when you use the switch on the engine. It will be a fine light hum.

Are you sure you have the right model number and / or the right box? See this thread. https://ogrforum.com/...-proto-sound-systems

This is what the box is but on the mth website it says the box was miss printed and gives the 30-1116-1. I don’t think it has the sounds since it doesnt have a (p) at the end of the number. I got the smoke unit working but it seems noisy.
THat is a Conventional DCRU with whistle board. No chuff, no integrated smoke, no battery, mechanical coupler. PS-1 upgrade requires gutting and installing MTH 2 piece board as an option. I have that model sound chip.
Or to the PS-32 steam upgrade. So there are alternatives.
As far as smoke, there is a switch under engine cab is that on? Lack of smoke can be simple issues and the smoke unit is rebuildable, unless it is the early seuthe model, in which case replace. I have them in stock too. E-mail in profile. G
