I have a Kenwood KAC-742 that will not turn off. I have the remote wire hooked up probable, I tested it with my DMM and the 12 volts goes away when I turn off the ignition. Has anyone ever heard of the internal relay that the remote wire switches on and off going bad? I cannot think of anything else this could be, other than the contacts are just stuck closed.

Does anyone know of an external relay I could purchase and just have the remote wire control that? It would need a 12vdc coil (obviously) and the contacts would probably need to be rated for at least 20 amps, to handle the power wire's load.

Any help/ideas is greatly appreciated. Thanks in advance!
