problems with lionmaster

Hi,

   Could be the odyssey sensor magnet. It's located on top of the rear motor I think.

If its damaged strange things can happen.

Before you resort to taking a look inside the engine try a full reset as shown here.

Certainly sounds like an Odyssey failure.  As Nick says, the most common failure is the magnet ring.

Thanks Nick, but that didn't work. I'm pretty good with this stuff is the magnet a hard thing to fix gunrunner?

Hard is a relative term.  If you have the Pittman motor with the setscrew in the flywheel, it's simple.  If you have the motor with the flywheel pressed on, the flywheel may have to be pulled and the retrofit flywheel and magnet kit installed.  The trick is pulling the flywheel, you can't pound on it to remove it, you need to use a wheel/gear puller.  I don't know for sure what that locomotive has internally.

Edit: I looked up the Lionmaster Challenger, it has two motors with the pressed on flywheel.  If the magnet is cracked or broken, the flywheel has to come off.  Below is a picture of the unavailable motor with the flywheel magnet, note the magnet is installed from behind the flywheel, there's a rim that retains it.  I'd normally recommend buying the whole motor, but they seem to rarely have them anymore.

Thanks John, Maybe I should send this back to the guy I bought it from, I always have crappy luck on this stuff!

Well, if it's the magnet, then it can be fixed without too much expense.  OTOH, if the Odyssey DCDS board has failed, that's a $100 item.

First step is to check all the wiring, a loose plug could cause the issue.

Or go to a back emf cruise board and eliminate the magnet and DCDS board.  Cheaper around $70.  G

Hey john it's the magnet alright! So what should I do now and where would I get the part? and thanks by the way!

Lionel stocks the part, but you'll have to find someone to pull the flywheel off the motor.  They also have a flywheel replacement part with a setscrew.  Here's the two pieces you need.  The setscrew flywheel avoids having to press the flywheel back on the motor, which can be a pita to get spaced right without a press.

Hey G, thanks for the reply. Would that be the cruise commander M from electric railroad? 

John, what do you think I should do. Or what would you do?

Well, for about $12 or so, and of course the shipping, I'd probably just put the new flywheel and magnet ring on.  OTOH, many folks like the CC-M performance better, and it does give you 100 speed steps.  Either way is good, the CC-M will take a little more than plugging it in for an Odyssey setup.  You either have to pull the pins from the 6-pin connector and put them into the 4-pin shell or hack the wires and splice them to the supplied 4-pin connector.  I always opt to pull the pins, I hate to splice things if there's a neater way to do the job.

I had the magnetic ring break on a TMCC loco, darn thing took off like a bat out of heck!!

I went with the Cruise Commander and it was like having a completely different loco, plus I didn't have to worry about the magnet breaking again!!

Good Luck!!

I had one that the ring broke and took out the DCDS with flying pieces.  Needless to say, it also got the CC-M.

John, Nick and Jeff, thanks for all the input, I knew I would find the answer here on this forum, Mark

Yes.  But it the magnet only I would do for the magnet first.  G
