I have a 2002 Ranger Comanche 519 and after being in a downpour a couple of weeks ago, I am experiencing electrical issues. I first noticed when I attempted to set my livewell aerator and turn on the pumps. I set the aeration to "L", but when I hit my pump button there was a distinct click from the fusebox and everything turned off. Now, none of my pumps (aerator/bilge) will come on. The only buttons that work correctly are the lights, but I have not tried them with the lights actually in place. When trying to operate the tilt buttons on the bow keypad, I get a split second of function before everything shuts down. I feel like something is limiting the voltage allowed through the circuit board or wiring, possibly due to a faulty circuit board (or parts on it) or faulty keypads. Has anyone experienced this before or know a way to check the parts in question?

That on and off switch mounted inside of the rear compartment for the accessories is a breaker, replace it.
