Fed Sig PA300 not working! Need help

[OlivePizza]

Hello guys


i have recently bought a Federal Signal PA300 (MSC) and a Fed Sig MS1000. Both are very used.


The first time i tested it by connecting the wires to the speaker (see pictures) and to my battery ( red and black wires ). it worked just fine.


The next day i try to use a charger for the car battery as a power source (probably not a good decision), there was no sound coming out just the lamp was on.


Then i went to my car to connect it to the battery, now there is no sound and light at all.


I dont know if its either the charger, that damaged something or its something else wrong with it.


I dont really have knowledge about all these stuff thats why i try to get help here.


Thank you in advance.

Look at post 7 for the PDF.


Try a 9V battery and touch the leads to the speaker it should make a sound.

Can you hear the siren oscilating?

here you can see what happens.

nope

Are you just using the paddle switch or turning the selector knob also?

im turning the selector knob also and the speaker makes this noise when i go from radio to manual.

Then it's safe to say it's a siren problem, not the speaker

could it be something with the wires or is it usually a transistor problem ?

 

[chief1562]

Well at least we heard a chirp from the speaker.


No PA either?

unfortunately i cant test that because the mic got cut off.

 

[OlivePizza]

Does anybodyy have any ideo on what could be wrong??


Please i need some help.


Thanks

Since the mic is cut make sure the wires are not touching. If they are it will cut siren off.

Thats a good point. I will try that.

If you say the pilot light doesn't come on and there's no sound, then I think you might have blown the fuse by connecting it to the battery charger. Replace the fuse and try the siren again.

the light comes on, but not all the time, just sometimes.

thank you soo much, you were right. I would never have thought of that.

It's one of those things that people just don't consider. They assume that if the mic was cut, it's no longer an issue so they don't think about it.

The mic of my Pa300 got cut and i want to know how i could fix that. The best case would be if i could use a non orginal FS microphone for it. But my question is which mic do i need and how can i find out which cables i have to connect to the cables of the pa300.





Here you see the four cables that went to the mic (black, blue, white, red).





Thanks in advance

If you're not sure about which wires go where, be very careful. The easiest thing to do is to go to Federal's website. There you can access the manual to the PA300. There is more than series of PA300 sirens, so it would be helpful if you know which one yours is. The manual should provide a full wiring diagram. But if you're still not sure, they have an 800 number for help like that. Good luck and don't "fry" the poor thing!

I'd think that all FS mics will have the same wire configuration. I actually think I have a NOS mic with connectors on it for the PA300. I'll try to find it.

Spoken like a true troubleshooter.

That would be nice. Thank you

I gave you the PDF info on the PA300 in your last thread.http://elightbars.org/forums/attachments/f18/41731d1349218014-manual-thread-installation-manuals-repair-manuals-etc-pa300.pdf


Here it is again you can find it ubder the sticky in Vintage and Collectables. Titled manuals.


Not only that but you have a pic of where the wires go already.

thank you


but i couldnt find a mic for this pa300 model so my question is if i could use another FS mic with an adapter, i would cut off, and which cables would come out of these mics?

 

[chief1562]

Someone else mentioned it.


Most all FS mics are wired the same.

I used to be able to replace one of those in less than 10 minutes..

i guess i wouldnt need much longer if i have one that i know would work forth pa300.


if you still have one let me know.


thanks

I couldn't listen to the video you had here at the library, but I'd guess that if you get some PA sound and some static, it's probably the output transistors. They can get blown very easily.

I had a decent FS mic, but it was designed for an Interceptor or PA200 and had the Motorola style plug-in.
