    Hi fellow boaters,

    This is my first posting and I feel I can help here. I am a Sea Ray dealer and have found this is one of the most common problems we encounter. One common problem with Sea Rays is the wiring at the battery. There are multiple wires and they sometimes can have black loom or different colored ends on them. These can sometimes during a battery change cause the wires to be hooked up to the wrong post. I have attached a picture of a Sea Ray 220 Sundeck we have in the showroom.

    Note the cable in the middle has a Red end but guess what it is a Black wire. This controls the main circuit for the dash. Just switching this one wire will cause the problem you are experiencing. Everything you are describing, power low, switch batteries, no power at all sounds like a story I've heard many times before. I hope this is it and solves your problem. Good luck!

    Now that you say that, I remember that exact thing happening to me a few years ago. Good analytical thinking! I couldn't put my finger on it, but it just wasn't making sense that you'd all of a sudden have a major problem just from changing batteries.

    Problem Solved!

    Thank you everyone for your diagnoses!

    Turns out it was the starter fuse. That thing was hidden on the starboard underside of the motor and looks nothing like a fuse I had ever seen. Take a look at the attached image of the culprit!

    Anyhow, it's 82 and sunny here at Lake Hartwell. I am off for "a test tour." :wink:

    Thanks again everyone!

    We had a very similar problem in our 2009 Sea Ray 230 Sun Deck. No power to gauges but blower and a few other things on the dash worked. Would not crank - dead silence. Batteries showed plenty of juice. Went through a lot of the solutions recommended here including looking for tripped breakers and blown fuses. Turned out it was the 5 amp fuse that dangles from the red wire connected to one of the two batteries. SR even conveniently supplied a replacement fuse taped to the wire, so this must happen a lot. We recently had a lot of water in the engine compartment due to 3 inches of rain (yes compartment was closed; don't ask me how that much water got in there when it was on the lift) and the hubs was power washing the boat (though not inside engine compartment of course) for spring cleaning, so maybe it was water-related. Took all day to figure it out, but at least it was a cheap solution!

    2007 230 Select 350 MAG Bravo 3 here. Same as above - all dash switches worked except for the start switch. And the stereo had no power. All fuses under dash were good. Fuse hanging off the battery (40 amp in my boat) was good. The circuit breaker on top of the starboard exhaust manifold was good.

    Under the cowl there was a small 50 amp circuit breaker on top of the back of the intake manifold. That had tripped and when reset all was well!
