Batboard

I got a service call for "A radio that won't stop transmitting". I got on site and turned on vehicle and master switch. I made sure that radio A (CDM1250 vhf) radio B (cm300 uhf) and the RICK were all turned off.

I turned on CDM1250 and it broadcast to dispatch on all channels fine. I turn on the cm300 and it doesn't seem to be going anywhere but space. I "enabled" the rick and when I ptt on the cdm1250 the RICK cor light activates and will not deactivate once I remove my ptt on the cdm. I have to "unenable" the rick and then the cdm finishes hitting the tower and 2 seconds later stops transmitting. The cm300 when I ptt it with the RICK on nothing happens so I think it is just a 1 way set-up on the RICK.

Any idea's????

Got a spare rick to test with?

check the cables going from the rick to the radios, make shure they are not worn thru and arcing out to anything. And has this vehicle hit anything lately, even a big pothole that could of jarred the internal switches, the switches could be stuck between contacts?
