I recently picked up a used Lionel Santa Fe Reefer Hot Box (6-29812) and for the first hour it worked well, good smoke, sound & blinking red LED wheel lights. Then it really started to smoke!!!!! When I realized the smoke from the car was more than the smoke generator, it was to late. Completely fried what I think is the voltage regulator (board 1) for the smoke generator & melted the internal wiring.
I looked on line and called Lionel for a wiring diagram on the internal components and I came up empty. Lionel indicated they have no wiring diagram and no longer carry any parts for the Hot Box cars.
Is anyone familiar with the smoke generator and the other boards in the Hot Box. The only number I was able to get off the smoke generator is MR B01. The rest of the markings on the smoke generator board is scorched off.
Board 2 is connected to the LEDs and board 3 is connected to the speaker.
I would like to salvage the smoke generator function and the red blinking wheel LEDs of the Hot Box car. I am not concerned with the sound effects from the Hot Box as I am using a current Lionel sound boxcar for the sound effects.
Whatever assistance can be provided in identifying parts would be appreciated.
