I have a 2004 Rinker Captiva 282 running 496 Mag and Bravo III. Boat came fitted with a Quick 'n Quiet Exhaust. Last time I went to use it, the exhaust would not switch to quiet mode. I have power to the connectors just before the solenoids. I feel I am missing something, because it seems unlikely both solenoids would fail at the same time. Is there a common wiring component I am overlooking that may be causing this. Any help appreciated! Thanks. Simon
