I want to plug in a D type external speaker into our Motorola T5419. I have tried making up a connection with a 2.5mm stereo (3 way) plug but the radio just transmitts. I'm guessing it needs a four way 2.5mm plug. Any ideas. I have 6 to wire up for our volunteer railway group. We only want to listen and do not need the microphone connection remotely connected.
I am looking for the same wiring diagram. The headset Moto sells is a single earpiece with microphone, so how does that end up being a stereo connection Neto? Just curious how, or is there also a full headset with microphone? ( I dont' know, just asking)
Would this be a 4 ring TRS connector? Sleeve = ground, then left, right, and the tip as the microphone??
I have a commercial motorola talkabout headset and the first thing I noticed was the connector is a three ring but 12 mm long instead of the usual 11 mm long. So basically, a standard 3 ring wont go in far enough. I don't have the wiring diagram though. Whatever wiring their using, its different from a standard cordless phone headset wiring.

Re: Wiring diagram for accessory plug needed.
Try first to plug the conector to the radio then turn on
This radios "reconizes" if it has an audio accesorie plugged to it. and need to plug first to turn on.
This audio accesories works with stereo plugs. So be sure that you are using the corrects terminals
I will check for the wiring for this earpices. as soon as I can.

Try the following: join yahoo group Specific to your radio Make & Model, you will need to provide as much info as possible to the team there so they can assist you, you can also download manuals, diagrams and other goodies for your radio(if available) and all this is free.
I hope this is useful to you and thanks for your query to FixYa team.
You have the correct external speaker connected, or a generic?
Some radios require certain external speakers to work properly, and generic speakers aren't always the solution.
Motorola 2-way radios of the model you have, may well come under this bracket.
Other than that, all I can suggest is: join yahoo group specific to your radio Make/Model, and the team there will advise you what's best for your radio, plus you can download manuals, schematics and other goodies for your radio and it's all free.
Your concern could be the internal speaker of the T5000. This could be verified by attaching an external speaker or a headset compatible with the unit through its accessory jack. Should this be the case, it of course would require replacement. Though Motorola speaker for this model is proprietary in design, those made for Alinco, Icom, Kenwood and/or Yaesu should also work. The only concern would be getting one that will fit the physical mounting limitations of the front cover.
In some instances, it could be the volume control developing blind spots along its carbon pad. A spray from an electronic contact cleaner should do the job (albeit temporary).
It is also possible that the Interference Eliminator Code setting is different with that of the TX radio.
Worst case possibility is a defective electronic component (such as the op amp) which would then require the professional services of a qualified communications technician.
Hope that this be of help/idea. Pls post back how things turned up or should you need additional information.
If indeed radio #1 has a mic problem, this may be confirmed by trying an external speaker/microphone plugged into the accessory jack. If still a no, then its not the mic but possibly the modulator circuitry. If there is transmit audio with the external mic and hence internal mic is defective, the unit would have to be pried open and the defective component replaced. The internal mic is normally an electrofet 2-3 terminal soldered to a shielded wire and physically attached to the front plate.
Alternately, another possibility is that radio #2 has its Interference Eliminator Code enabled/activated. This is indicated by the presence of small sized digits on the top right of display. If this is the case and no similar digits are displayed in radio #1, then radio #2 will not allow any received transmission to be heard. Along the same line of reasoning, if the code is activated on both radios signified by the presence of the 2 small digits, and radio #1 has a problem with its CTCSS (code) generator, then it would also prevent reception of radio #2. A way to verify this is by deactivating/disabling the Interference Eliminator Codes on both radios.
On certain occasion, it is also possible that radio #2 has a defective speaker. You should be able to verify this by plugging in an external speaker to the accessory jack of radio #2.
Hope this be of some help/idea. Pls post back how things turned out or should you need additional information.
It would seem that this is a problem with the contact/switch of your Motorola T5700. When a headset, ear piece or external speaker is plugged in, an internal switch transfers the connection from the speaker to the external. This is better illustrated in the image below.
Initially, you can try an electronic contact cleaner. If that doesn't work, you may have to open the unit and manually scrape off any corrosion from the contacts/terminals or slightly bent it to improve contact.
