We have a new to us ambulance that is running a SVP SS741-MG Siren 200W. Problem is, it doesn't work. It keeps blowing the #2 fuse and I can't get any tones working and can't hear them coming from the box either. I've looked at it and can't figure out what's going on. All the components on the board look good all the wiring appears good. It turns on, speaker diagnostic is good, but no tones. My gut is telling me the tone generator/amplifier for both speakers went bad... Any ideas? Thanks!
