Hello all I have a friend with a LionMaster SD80 6-28332. When odyssey is turned on it almost always just takes off at full speed. With ODY turned off it operates as expected with no cruise. I’m trying to get a shopping list together for the parts sale this weekend and unfortunately I still don’t have the locomotive in front of me to look at (we’re both busy people). When I do take a look at it should there be anything else I should watch out for other than the standard loose connection/ broken wire. I imagine if I don’t see any obvious I’ll be getting a new DCDS but just figured I’d check with some people smarter than me.  

Thanks in advance

Happy Railroading!

This is an early Legacy model.  If the tach reader is faulty, the engine will take off and go a few feet and then stop.  If the DCDS is the problem, it will take off and never stop.  The indications of the tach reader can also be the DCDS, but I tend to suspect the cheapest component first.

Check for wiring issues between the tach reader and the DCDS if it stops after a few feet.

Well it was pretty simple, wiring was fine. But as you can suspect if the flywheel doesn't turn with the motor kinda hard to get a speed reading . Both set screws were loose kinda weird but I like simple, might need to go back with some thread locker, they are so small don't want to over torque them and didn't feel as tight on the shaft as I would've liked but it works
