Scuff it up and shoot it with self etching primer. Eastwood works really good.

I vote yellow as well. Good luck in obtaining this siren. If properly cared for, it should last you many years, if not decades in the future.

By "stuff it up" im assuming that means use some 200+ grit sand paper and and it all clean the dust off and shoot it?holler wrote:Scuff it up and shoot it with self etching primer. Eastwood works really good.

Scotch-Brite pad works well for that too.

Will post a longer update and pics tonight, Figured out the AC side issue but then had a big set back happen with the logic board 
so I might have had a major set back

How about painting it in Barbie-pink?

Ok, so now that i finally have enough time heres the update.
Saturday I spent most the day working on the AC power supply and getting things re-wired for the AC side to work. After looking at the wires I found a 12 inch section of wire that had come unhooked and looked like it had been shorted out (Believe it was just bad wire) I replaced that and hooked up the AC box to the controls. With a few last adjustments i had the control board running and motor starter clicking in attack all from the AC power box which was great! So that means the sirens AC and DC sides work fine. After about a 30 min break for lunch I went back out and we went to test it with the siren hooked in. I turned everything back on (prior to hooking up the head) I hit the power switch on the control board... and nothing happened.. looked at wires saw nothing wrong. Turned it on once again to find still nothing...then it happened, POP and there went the transformer on the control board and a resistor I will be calling around to Werden Electric, Gifford Electric here in Fort Worth which is an ASC dealer and ASC to figure out where to go from here. I'm hoping I can find the proper transformer and resistor and replace them rather than replacing the entire board. I'll keep you posted

That's a big disappointment 
. Hope you can get the board fixed. The good news is that it is still made, and parts, hopefully, will not be too hard to find. It puzzles me though why it shorted out 
. Good luck getting it working again.

Now that the camera wanted to work here are some pics
AC Power Box 240VAC in 50VDC out.
Control Box with DC battery chargers and DC side motor starter and battery leads.
The next 2 pics are of one of the three boards that make up the RTU control unit. And show the damage done when the transformer popped
Has anyone seen anything like this? I can't tell if this is a fried part or something that should look like that..
The transformer on the right is what popped and you can see the resistor labeled R4 is toast!
The update is that the control board is now @ ASC in Wisconsin and they're going to look at it and see what damage has been done. The guys there have been extremely helpful and easy to work with. Most of them seem stunned that I privately own this one. I will update more once I find out what's wrong with it.

hard to say; that part that looks like a power resistor seems like it got hot, but w/o knowing what its value is supposed to be it's impossible to tell. The bridge rectifier directly below it doesn't look amiss but semiconductors can go pfft without any external damage to the package.Has anyone seen anything like this?
