I have a PS2 Premier Dreyfuss Hudson (#20-3045).  When it runs, the sounds cut in and out. Otherwise, it runs fine.   It does have a BCR in it.  I checked the tether and it seems OK.  Track is clean. Other engines run fine on the same track with no sound issues.  I did look at the speaker and it looks OK, no signs of a bad speaker (I have seen some so pretty certain I would recognize a bad speaker). Appreciate any thoughts on what else I should check.

how long due thew sounds play when you power down in conventional ?if the sound stops immediately your battery is weak or defective. start there if battery checks OK try a conventional reset.if you use DCS you can reset from the remote,the sounds should play 3 to 6 seconds approximately,if sounds cut off immediately battery is dead!

what is the item engine number?

also unplug all the connectors on the PS 2 board and  re-seat them,could even be loose connector or wire?

P.S. since you have a bcr do you wait about a minute when you first power up, it takes time to charge the bcr super- capacitor.

i have in my ps 2 engine and if i don't wait long enough my sounds don't work right either. you can try a dcs reset if your using dcs with tiu !

good luck

you have a ps2 with 8.4 volt battery in the tender,if your bcr doesn't hold a charge could effect your sound!

check out the PDF file, shows all your engine parts and battery,i would try a 9 volt alkaline battery first for a quick check ,if sounds return to normal, bcr or charging circuit is your problem!

 

good luck

Speaker can be failing despite not corroding, so a visual check won't always work.

 

The Yel and Wht wire on the end of the PCB that the tether plugs into are also a high probability.

 

After that your looking at hardware or corrupt sound file, but the higher issue is hardware fault on the PS-2 5V board.  G

I had the exact same issue start happening to me over the weekend.

I bought the engine new in 2002 and has run great till recently.  The sounds cutting out for fractions of a second  do not seam to be related to curves, and I also notice with the smoke unit on, the light start to dim on chugs.

Wish I knew if it is a bad board or something simpler. 

I have not taken it apart yet.  If it were not for the lit drivers, I would have no problem upgrading this to a ps 2 3v or PS3 myself.  I am  just not sure how to deal with powering the 7 lights the engines has with a standard upgrade kit.

most tech's I talk to just tap the power for the lights from the headlight so that when the engine is on with the headlight on your other lights will be lit also.

or you can get power from the center roller and the chassis ground, then anytime your track is powered up your lights will all be light , it's clearly your choice either way they will work  for you!

good luck which ever way you choose!

 The PS-2 5V dreyfuss has the board in the engine so the mars and ditch light connections are used to run the driver lights.  2 to a circuit.  RJR is correct your at the limit with 3 bulbs on a circuit.

 

Using headlight to dual run the markers with a limiting resistor is ok.

 

Mike, I would change out the smoke fan motor, it may be going bad.  That might resolve the dimming of lights on chuff.

 

It could be an audio amp going bad.  That is repairable.

 

I would check speaker, wiring on PCB as mentioned, than reload the sound file. If still cutting out, I would test out of engine, and replace audio amp.   If the 5V fails, the best solution is a PS-2 3V put into the engine.  That is an easier fit then the PS-32, though I squeezed one in.  G

Mike,

If it were not for the lit drivers, I would have no problem upgrading this to a ps 2 3v or PS3 myself.  I am  just not sure how to deal with powering the 7 lights the engines has with a standard upgrade kit.

Ste you referring to the Premier Dreyfuss?

 

If so, I recently converted mine to PS3 using a PS32 board. All the lights, including the driver illumination, are handled exactly the same as with the 5 volt PS2 board. The board is in the boiler.

 

No rewiring is necessary.

 

Further, it was while doing the conversion that the sounds cut out. I touched up the tether's solder connection for the speaker, in the engine, to correct it.

Mike, It is plug and play.   The 8 pin connector, which has your tender and engine marker lights also has 5 additional outputs.  2 ditch, 2 mars and a beacon.

 

Each output can control 2 bulbs normally. Except the beacon which is always a flashing LED when used.

 

So you have 3 double bulb connectors for your driver lights.  3 of the 4 Ditch/Mars are set for constant on by the sound file and run those lights.

 

In your case your not doing a traditional upgrade, you just installing a PS-32 board with 5V connectors and removing the battery and wiring, and replace the speaker with a 4 ohm.  G

I am pretty sure I can get a new speaker from MTH, but I understand there are other suppliers that may offer improved speakers.  Appreciate any sources.

I have no sounds at all now.  I have looked at the tether connections in the tender.  I would like to verify the wires are there the way they should be.  On the Board where the tether is connected, from left to right my wire colors are:  white, yellow, red, orange, black, green, blue, gray, brown, purple.  Is this correct?

 

Should I just order a new tether and connector board along with a speaker?

JDA.  I've been/am there.  Replaced a tether and it did nothing.  Per Barry's recommendation, you have to get into the loco and check the wires on the tether socket.  Somewhere Barry has posted details of these connections and resoldering them.  This is apparently the  most common cause, but not easy to access..  If the sounds used to work correctly, then the wiring connections in the tender must all be correct---relocating them is looking for trouble.

 

If you want to spend all that money, you may hit pay dirt, or you may not.  I suppose you could order a new loco harness with socket, but I bet it's not cheap.

I GUESS it could be a component that fails when it heats up.  I only know of 2 persons to whom I would send a board for repair.  One is MTH in Columbia; the other is GGG, based on his reputation.

 

Given that it is apparently an old 5-volt system, I'd probably gut the loco and put in one of the 3-volt upgrade kits I have on the shelf or a new PS3 kit.  If I didn't consider myself capable of doing the switch, I'd have GGG replace the board with a PS3/2 board.  That is a job that several techs who post would be qualified to do, but not all.
