I recently aquired a few powercall sirens anyone in the past has
every worked on them ??. Besides the final output transistors that
go bad what would cause no power to a unit when the neg and pos
leads are good???. Is there some type of internal fuse that goes bad ??.. Any help would be appreciated......
