Yes, apply 12v to the small wire and it will activate the brake solenoid.

Yes, yes they would.

In the 70's and 80's Vermont and Maine also had police that ran blue only.

I made a mistake in my above post. I was in a rush to get out the door to get to work. If both black and yellow need to be connected to ground for the side shooters to work then you would need a different switch than the one I linked to. You would need a DPDT switch which has six terminals on...

If you want to use the spot without strobes and strobes without spot and never the 2 together the simplest way is a SPDT switch like the one in the link below. First check to see if connecting positive to the light and ground to the yellow only will still activate the strobes, if so then Connect...

Back in the 60's the local VFD had a rescue truck and 2 engines. Outside the front of the firehouse was a pole with one of these mounted in the middle and a bulb in a glass encased socket on each side. The center light represented the rescue truck and each side light represented an engine. The...

What the heck, if it's in decent shape I'll take it if you can get it. Gladly paypal you the money and shipping cost.

You are correct, positive to the large gauge wire and ground to the casing. Be sure to clamp it down as they have a lot of torque. The small wire coming out of the front housing is obviously for positive to the red light. These could be used on any type of emergency vehicle, fire trucks, fire...

Boy is this ebay seller confused. Screen shot of listing below.

The center rotators do look like smart rotators or select alerts which when rotating would provide a front facing clear flash and when parked would operate as takedowns. The same thing could have been accomplished by making the front facing sealed beam operate as alternators or steady burn. The...

Wow, you really "blue" it with that one.

FedSig and Whelen actually glued 2 plastic lens halves together. FedSig also did it with glass domes but I'm not sure how they attached those halves together.

I'm pretty sure the top does have a silver painted coating on it. I bought a pallet of those years ago to flip and some had deep scratches making it possible to see the layer of protective coating. I think Whelen did this for the purpose of keeping the top from corroding/tarnishing/ in the...

Yup, that's it.

As robust as Federal Signal items were in the day it amazes me that they relied on that thin wire for such a vital function. Imagine with the freezing temps in NYC driving around on patrol during freezing rain or a snow storm blowing moisture into the front of the siren. The flapper would freeze...

Just make sure you check the grease in the gear box. It's usually dried out. Get it all out and repack it with automotive grease.

Nice score. It does seem complete. Doesn't seem to have seen much use. I've gotten ones that were so heavily used the stainless wire wore through the shaft and were no longer there.

Definitely out of a Jetsonic. I parted a Jetsonic out once that had that same setup. Unfortunately the switch wasn't hooked up to anything so I can't help with its purpose.

My question is what did you initially hook power to? The 2 brass posts in the black insulator are NOT positive and negative. They are supposed to both be positive, one for the siren the other for the front light. Ground is through the siren body. So you would attach positive to the brass post...

Here is a pic of the inner workings as described in my above post. I haven't had a chance to repair this one yet so the hole in the gearbox is where the shaft would stick out that the half circle stainless wire would go through that connects to the rotor.

The 4 screws on the front of the pulsator cone secure a tube inside that houses the flapper that attaches via a short rod to a crank on the side of a gear box screwed to the bottom/back of the tube. On the back of the gearbox is a small shaft that has a half circle stainless wire going through...
