K Line K3470-1295CC NYC TANK ENG Burned Up MTR Driver Bd

Looks nasty. I guess you could verify if sound still works by placing the engine on the track and turning off the TMCC or Legacy base and see if sound comes on. You can replace the motor driver with a cruise M but you will have to add a chuff switch as chuff is generated by the K-Line cruise board.

Cruise M will be a drop in replacement, do you know the root cause of the nuclear meltdown that occurred??.....did the radio board take the hit for the team as well?....Pete is correct, you’ll need to add a way to make the chuff signal....Kline Cruise makes the chuff, ....I’m used to the Kline Hudsons with the mechanical chuff switch...

So far I think the motor drive board shorted somehow...maybe the reg chip next to the diode rectifier...if that’s what that chip is. Then the area under the multi pin connector at the far edge of the board got very hot...heating up the wiring there and the sound power supply below it.

I think I recall somewhere John saying his specialty dish this past month was fried Kline with a side helping of goopy wires.....he had a few go down....

K-Line virus?

This is a classic failure Chuck.  If it's any consolation (probably not), I have several of the K-Line cruise boards in a junkbox with the same area burned up.   Apparently, there's some design flaw with that board as it's very common for them to go up in smoke.

I'd take a toothbrush with alcohol and scrub the back of the sound board, it's probably not dead.

You can replace the K-Line cruise module with the Cruise Commander M, but there's a catch.  In the tank engine, K-Line generated the chuff from the cruise module, and also controlled the smoke fan.

I have a tank engine sitting in the closet with a dead cruise board, I'll be upgrading that one with the Cruise Commander M, Super-Chuffer II and Chuff-Generator.

Hi John

Cruise Commander M, Super-Chuffer II and Chuff-Generator sounds like the plan. I put it in a box in the garage, so it's going to be awhile probably. Except for the mdr board and the sound board being with goo, the rest of it looks fine. I need to put a couple one inch shrink tubes over a few wires that got lightly cooked on one spot. Thanks for the tips and the reply.

I'll try to remember pictures when I do mine, that way you'll know what to expect.

Great! I’ll look forward to that. Thanks.
