PA-300 problem

Wed Jul 19, 2017 1:31 am

Hello, I'm looking for help. I have a PA-300 Series 690000 that randomly turns on when power is applied. It has surprised me a few times when I start the truck. It works properly most of the time, but sometimes it peaks and holds while in manual mode. The other tones work properly, except Hi-Lo. When the siren is malfunctioning, the Air Horn sounds in Hi-Lo. All jumpers are in the correct positions. wiring is good. Power is through a cigarette lighter that remains plugged in. No horn ring is installed. Radio rebroadcast is connected to a 3.5mm audio plug for iPod/CD player input. Thank you in advance for any help!
