TMCC shark aquarium car reset code?

Have you tried generic codes, say start with 1?

I have tried 1-9 but still no luck witht the motor. I have the sounds, couplers, and light panels working using 8 or 4. The next step will be to test the motor. The car uses a DCDR motor driver board just like an engine so it is either that or the motor that has failed. I wish I could find a wiring diagram, there is a puzzling 3 pin connector with some sort of electical component that has it prongs in the plug. I have never seen that before.

I'd test the motor first, just unplug (or unsolder) a wire and connect 5V DC to it.

I think you may be talking about a TO220 package, I see that a lot in MTH locomotives, bolted to the frame with a 3-pin connector to them.

Pictures and an exact part number from the motor board would help.  If it has a DCDR, one would think it also has an R2LC somewhere, it needs that to make the motor go.  The plain DCDR won't do anything without a PWM input signal for direction and speed.

It does have a R2LC as well as the DCDR board. The 3 pin component on the connector is a tiny black thing about 1/4' square and just hangs there. I'll try and get some pics on later.

Does the black thing have anything printed on it?  What's the exact model number of the unit?

I don't see anything in the Parts List that matches that description.

The Hall sensor?

That's what I was thinking, but it should be outside on the truck!   If it's inside, that's a problem.

Here are some pics. It is Lionel #6-19868. The hall sensor is where it should be, the ? component is wired to the

DCDR board and has the number U28 912 on it. You can see it on the blue/green/yellow wires in the 2nd pic. I'm thinking that it "hard wires" the driver board to a low voltage output. The motor tested fine but it would go too fast at full voltage from a normal DCDR. A driver board this big is serious overkill for that tiny motor and I'm surprised that it would fail at such a low load. I do have a spare DCDR board from a cruise upgrade, it looks like it will plug right in. Should I give that a try?

Neil

Those numbers don't mean anything to me, nothing comes up on a search.  Are those bare wires going to that connector?

 I have never worked on on one of these cars, I believe your motor driver is a odyssey 1 motor board,  DCDS. The yellow, blue and green wire is plugged in to the spot that the motor sensor plugs into, the other end looks like it has a triac or similar device. This is probably used for speed control of the motor without having the encoder board mounted on the motor. Also I don't think your DCDR will work as it don't have the provision for the motor sensor plug. I would give CS a call on monday and see what they have to say.

Thanks Bill, I think you have it right. I looked on the Lionel parts site and found this:

691DCDSEA0 DCDS / ODYSSEY 1 MOTOR DRIVER (AQUA CODE)  $99.95  Unavailable

Aqua code is for the aquarium car but at $100 it's too much even if it was available.  There must be a way to use a DCDR, I don't need odyssey swimming sharks! Are the pinouts the same for both boards? Won't the R2LC control a DCDR too?

Neil

Neil

   If you could use a DCDR, you probably would need to change the R2LC also, as yours has the Aqua code, what ever that is. Was the swimming sharks speed adjustable or one speed.

Bill

Call Lionel.  They are still going through parts and might have not been updated on the website yet.

I have the Shark Aquarium Car and it works very well. It is the most impressive of all of the aquarium cars. The first time I turned it on (about 6 months ago) I had the same problem you have. After fiddling with it for about an hour it just started working. Not sure what I did to get it going.  I assume you have the instruction sheet and have tried everything.  Aux1, 0 is the reset sequence. Could it be stuck in conventional mode? What happens when you hold the horn down?

Let me know if you there is anything you want me to test with mine.
