Hey everyone. I have a Kenwood TK-730 that was attached to a Touchmaster Delta, and was provided power from one of the accessory switches on the siren unit. The speaker option was selected on the kenwood for monitoring radio traffic outside of my vehicle. After returning to my vehicle, I used the siren's pa system, forgetting the speaker option was still on, and the fuse to the siren blew, cutting off power to the radio as well. After replacing the fuse multiple times, the fuses kept blowing every time the radio was turned on (I believe it was because the speaker for the siren is the same speaker used for the radio's external monitoring). I think it was because they were both trying to power the speaker, so there was a back draw. The siren still works perfect, however, the radio doesn't. The radio still powers on and all functions work, except the accessory plug. The external speaker for in car monitoring will not work, I can no longer use the PA or Speaker options on the radio. Any suggestions on what happened or how to fix it? Thank you in advanced.
