 Yes, blew fuse in 80 watt transformer... replaced mother board, odyssey DCDR board, and new wiring. shorted with heat sink on, hanging from wires, not mounted on frame. Works ok with heat sink off. Gets really hot and dims lights in forward or reverse with heat sink mounted on DCDR board. Noted your DCDR heat sink board was insulated, original was not insulated... power transistors and heat sink should be grounded screwed to the frame... mine got so hot a transistor fell out.. using the now junk 80 watt transformer,, still has 18 volts with the handle off... will be disconnecting motors and the odyssey speed control.  TMCC all works fine until you hit go. Real bad voltage return short somewhere.  I'll find it, just don't how long it will take. Hope it isn't a bad new DCDR board....   From, Indiana

DCDR board mess.. Disconnected motors, heat sink on DCDR board, turned the red knob to go and it toasted real bad, just like it did with motors connected.. disassembled the chassis, looking for pinched wires, disassembled motors from trucks... front motor with speed control board has some strange issues with DC test transformer. Rear can motor ran fine.     Dash 9-44 TMCC with odyssey 6-18287. This model had intermittent problems, like just stopping and some times dropping out the track transformer. A year ago I replaced the Lionel odyssey board with an electric RR board... ran great. Had maybe 4 or 5 hours on it than it toasted... So were back with the Lionel DCDR board again, after I got released from helping farm.. The board was slightly toasted yesterday with the motors connected. It probably just finished what was already started.  I'll throw some more money at it again..  Note I haven't disassembled a heat sink on a DCDR board  that had insulation on it... yet.

Thanks   JSW

 

 

What are you talking about? Are you asking for help or just telling us all the things about a broken train in completely random order? So youre working on a Dash 9  model # 6-18287with odessey  and you smokes out the motor board? Buy a new motor board or upgrade it to an ERR board and don't pinch the wires this time. Zip ties do a great job of holding the wires in place on the chassis so you dont pinch them when you put the body on. Hot glue is great for holding wires up inside the body, just a little dab will do. Take your time on it and the repair will last.

Thanks Guys,,   found no pinched wires on disassembly, did find a broke wire in harness that connects DCDR-S to the speed control board on motor. Pickup wires and insulators and ground wires checked ok. Will order a new DCDR-S board and a couple of new motors. Wires and connectors look correct to t the odyssey wiring diagram. The TMCC works fine so far.   Like the remote, couplers and sound.   Will try again,, Thanks,, JSW
