trygmaya Posted October 13, 2013 Share Posted October 13, 2013 Hello! I am New to this forum, so i start With a small problem I have with my MTH F7 loco. I run it with DCS, and now I got a problem with the speed, I put the control on 1 mph, then it starts to run after one second, slow and then increase the speed up to top level without me using the control. Also the sound of the motor are the same all the time, as it was standing still! Anyone who knows what the problem are? Best regards Trygve Olsen Norway.

Rayman4449 Posted October 13, 2013 Share Posted October 13, 2013 Welcome Trygve! I would first check to make sure the optical reader face is clean and not covered with grease or something. Next check for a broken wire (there are three) that go to the optical reader. Other thing to check is to make sure the flywheel with stripes is clean. Most likely you prob have a broken wire or something. Raymond Quote Link to comment Share on other sites More sharing options...
trygmaya Posted October 13, 2013 Author Share Posted October 13, 2013 Thank you! I will try to check the wires and the optical reader, just love these MTH locomotives, I also have a VO-1000 who runs very well, I can only compare it with my one gauge Marklin V-100/212 who cost 3 times more! Hope I can fix the problem with my F7. Trygve Quote Link to comment Share on other sites More sharing options...
blid Posted October 14, 2013 Share Posted October 14, 2013 I had the same problem with a MTH 3-rail H0 F7 a couple of month back. The cable from the tacho board looked like it was connected, but the connector was not all the way in. After connecting it properly the engine works just fine.

trygmaya Posted October 15, 2013 Author Share Posted October 15, 2013 Thaks for the tip, i will try to fix it this evening! Trygve Quote Link to comment Share on other sites More sharing options...
trygmaya Posted October 20, 2013 Author Share Posted October 20, 2013 Now i have tried to check the wires and the optical reader, can not find anything wrong except a small cut in one of the wires, but it seems like its only in the rubber and not into the copper! The front coupler does not work either! The coupler problem and the speed problem occurred at the same time? Should I try to change the wires to the optical reader? It quite difficult and since it doesn't look like the copper inside is damaged I don't know? Don't have any service center for MTH here in Norway, so I am not sure what to do?

Rayman4449 Posted October 21, 2013 Share Posted October 21, 2013 I wouldn't bother changing the wires to the optical reader. The fact that you have noticed something else like the front coupler also not working seems to indicate something else. What I would do next is to make sure all the wiring harnesses are plugged securely into the Protosound 2 board. Next I would carefully inspect all wiring to ensure there is no bare or exposed wire that could short against other wires or anything. If everything else checks out then I would say likely need to send the Protosound 2 board in for testing. If you need that I can do that at no charge and can provide replacement boards if necessary. If the board tested bad would want to make very sure we checked all the wiring is good before dropping a new board. You really don't ever see these boards just fail but I suppose it can happen.

trygmaya Posted October 21, 2013 Author Share Posted October 21, 2013 Ok I will have an extra check on everything, thanks! Trygve Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted October 21, 2013 Share Posted October 21, 2013 It should not be an issue but make sure you press down on the top of the PS2 board to ensure the top and bottom boards are fully seated. Quote Link to comment Share on other sites More sharing options...
PAZGRR7315 Posted October 21, 2013 Share Posted October 21, 2013 Is it in a lash-up or try RESET ENGINE.... Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted October 21, 2013 Share Posted October 21, 2013 You could try a reset engine through the remote but what he is describing is the board is not correctly processing the information from the optical reader. Either because the board/optic reader is damaged or because of some wiring issue. Quote Link to comment Share on other sites More sharing options...
trygmaya Posted October 21, 2013 Author Share Posted October 21, 2013 I already tried to reset the engine, no result! But I will try it again! Thanks for all the tips! I don't feel like sending the engine back to the US but if I can not solve the problem I will take contact with you Raymond on e-mail. To see if I can send it to you!

Rayman4449 Posted October 21, 2013 Share Posted October 21, 2013 You're very welcome. Yeah because you are overseas sending the engine would not be my first suggestion because of cost and would in a first step resort to mailing just the PS2 board itself for testing if it comes down to that. Keep us posted Raymond Quote Link to comment Share on other sites More sharing options...
trygmaya Posted October 23, 2013 Author Share Posted October 23, 2013 I have checked the wires once more, tried to reset the engine one more time and tried to run it in a lash up, and there is still no result, It's strange because the PS2 board look very solid too me.

Rayman4449 Posted October 23, 2013 Share Posted October 23, 2013 Yeah, resets and lash-up will not affect the issue you are seeing. If there is a problem with PS2 board it wont always be noticeable. Other thing you can do is to make sure the optical reader face is clean by rubbing it down with a cloth. Quote Link to comment Share on other sites More sharing options...
trygmaya Posted November 1, 2013 Author Share Posted November 1, 2013 I have tried everything, no result, I think I have to send it to you Raymond! Trygve Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted November 1, 2013 Share Posted November 1, 2013 Sorry to hear that. I will send you my info if you want to mail the board to me to test. Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted November 1, 2013 Share Posted November 1, 2013 BTW no charge to test the board, just return shipping if it tests ok for some reason. Quote Link to comment Share on other sites More sharing options...
