My control box has gone out and I bought a later model that will not work. Its on a 76 ambulance and I cant find like the old one. Anyone have any thoughts on replacement for it?

I have lots of Whelen control boxes what are you looking for and why won't the one you bought work?

If both the original and the replacement do not function, I would look to take a trouble light and confirm the power lead is good. Although less common, check that the ground is intact. Hopefully you have a known working spare strobe head you can plug in to confirm all the lights were not killed for some reason.

I once had all the lights on a Federal Signal MX7000 die at the same time. I wasted a lot of time tracing wires until I tried a new bulb and found some spike had killed all the bulbs.
