question does anyone know where i can get my hands on a thunder bold or even a mini thunder bolt out where i live we cannot hear the city's sirens and we are prone to sever weather any time of the year i am a firefighter so the county government will allow me to have and operate one
are the 2 holes where the horn is attached the Rotor/Stator? or is there a chopper & stator in that whole compartment and the holes are where the sound is projected?
Federal began making 2 port caps after about 1970. It was cheaper to just make one kind of cap then to make two. All series C sirens have "dual tone" caps.
After the A series, Federal signal stuck the same chopper cap on all the thunderbolts, regardless of whether it was a 1003, single or dual tone. All t-bolts received a chopper cap with holes drilled and tapped for the solenoid bar and a divided stator.
Just a little update for everyone, I haven't had a chance to growl the armature yet but I did manage to test the field. The results seem to indicate that the field is totally dead and has an open spot in it since I found no hint of magnetism anywhere when power was applied to the coils. It appears in the video that the siren was running off the commutated force of the armature alone, hence the jerking, banging, noisy start and excessive sparking from the brushes.
Nice video, Jeb! Hopefully you can get that fixed soon. Btw, I'm gonna try to score one of the Nashville Thunderbolt 1000/1000T's this weekend, I'm hoping their the 1000T model.
It has a dual tone stator off a 1000T and the rotor out of a 1000 so that makes it a 1000.
No it doesn't need oil the bearings are permanently sealed and besides they are new bearings.
Just because the armature has a short or open spot in it doesn't mean the windings will be black. The windings on this siren look perfect, but a quick check with a growler will find the dead spot.
A growler is a device that you use to find shorted spots in armatures and see if they need a rewind. I will post a video of me growling both of my Thunderbolt armatures when my growler gets here.
Sweet! I always wondered where the copper motor was....know I know, the big little case under the chopper.........Y it never dawned on me beofre is a mystery
Well, i foundout today that my 1003 Has a burned up motor too. I'll show a video.

the tow large rectangulat holes is whee the sound comes out, but four of the 8 screw holes by the sound holes is where the horn is bolted on.

Why only one tone with openings for two tones?
Interesting.
Glad you saved it from scrap.
Thanks for the education about "growling".

Robert,

Thanks.
I assumed that.
Surprised they did not make more sirens with common interchangeable parts, especially the 2t22 cones (projectors), which are difficult to fabricate.

Is this the now 'Blunderbolt'?

Is that a 1003 stator? I know it's a 1000 chopper.

yeah hopefully you can score a dual tone model, because most of the ones I've ran across are 1000's.

Great video. I'm sorry that the chopper got burned up.

what kind of model 1000/1000T/1003 and was the winding balck or did it need oil

It has a dual tone stator off a 1000T and the rotor out of a 1000 so that makes it a 1000.

ok...whats a growler? :P does it test siren armatures like this one so you can rewind them? lol sorry for all the questions lately :P
