murphy models sound chip for 201

[controller]

Hi, I just purchased a Murphy Models sound chip for a 201 loco. I thought everything would work if I just placed it on the main track, but no. Reverse/forward ok, FO directional lights ok. No luck with F1, F2, F3. F4 headlight one end only. No luck with F5, F6, F7. F8 cab lights ok. Do I need to program this chip on the program track first?. I am using a Guagemaster Prodigy Advance. I am using factory default address # 3 at the moment. I will change it later, when I get it all set up.  

Thanks,

First thing I would try is resetting the decoder. Program CV8 with a value of 8.

This won’t affect the sounds in any way.

Thanks IT, I did what you suggested by resetting cv8 to value 8. I did this by programming loco on program track. When I read loco's decoder values on programme track, I get a reading CV8= 151. I know I am doing something wrong, but I don't know what.

Don’t worry about reading CV8, the value simply tells you who manufactured the decoder. 151 means ESU who manufacture the decoder for MM. This value won’t change even after reprogramming CV8 to 8 so don’t worry you haven’t done anything wrong.

Did you try the decoder after the reset?

Hi IT, Yes I did try the decoder after reset, but I am still only getting the same functions. Perhaps if I try to program the chip again, I might have some luck. Any tips would be very welcome.

Sounds like the speaker is blown? That or one of its connections is loose in some way. 

Inspect for any loose wires first off. If all looks ok you could check the resistance across the speaker with a multimeter. If there is no reading the speaker is gone

Are you getting any sounds at all?

[controller]

Hi Lads, I am not getting any sound at all. All I am getting is lights and fwd/rev. I have the loco since 2012. I never opened the loco, except to replace the chip to DCC. And that only means removing a small panel from the roof. I don't think I would be brave enough to take the loco apart, and do as you suggest. If I was to take it to Marks or Murphy Models, would they have a service/repair department?. I think it would be safer to leave it to the experts. After forking out 120e for the chip it would be nice to see it working properly.

Thanks,

Controller.

Sounds like it may be the speaker alright. Can you try the decoder in another loco to make sure it isn’t faulty?

[controller]

Thanks IT, The only other loco I have that has a speaker is a MM 071. I will give that a try.

Thanks,

Thanks Lads, I tried the chip in my 071 loco and success first time. Everything is working. So like you lads suggest, it may be a faulty speaker or loose wire in 201. I will take it in to Marks tomorrow, and let them have a look at it.

Thanks Again,

Controller.
