MTH protosound 2 issues

Ok You have DCS....

Timing is everything when powering up a dcs layout. There's a signal that goes out of the tiu called the watch dog signal. Any powered   proto-2 engine senses the watch dog signal and then knows it's in command mode and does nothing until instructed  by the dcs remote. This applies to any dcs engine whether added to the remote or not.

So what Am I getting at..We need to know whether your engine remains dark and silent when you first power up the tiu. Hopefully it does.

One question at a time... Does your engine start up with sound and lights or not when first powering up the layout (fixed 1)

Yes, DCS.  Sorry about the typo.  The engine starts up with sound and lights and immediately goes forward when powering up the layout. 

Next I guess we have to know whether you have other dcs engines that run  OK?? in command mode on the same track.

If so I think you're probably going to have to take the shell off and check out the wiring at the motor to see  If any strands of the motor leads are touching the motor casing . That's a sure take off for sure and probably not so good for the circuit board.

I'm not sure what else you can try, perhaps the unlock direction feature with the bell and whistle combination but I think you may have other problem if the engine is missing the watch dog signal. Even if the tach reader is not working the engine still should remain dark & silent and not move.

 Hopefully someone else chimes in. they will.  good luck

Thank You Gregg.  Other DCS engines run fine on the same track.  Thanks for the advice.
