No power?
Do you mean that when you attach the DESS lanyard to your dashboard and push the start button, it's dead?.....if so, then there are two things to listen to. First, if you have the proper DESS key and it works properly when you attach it to the dashboard, you should hear to audible beeps. If it's the incorrect one, you should hear one long beep. If the neutral safety switch isn't making making up to the engine in neutral, you'll also hear a beep and you'll not be able to turn the engine over. If you hear nothing, then your digital electronic security system is not allowing power to the MPEM or as stated in the other reply, you have a fuse blown. Since buying my Challenger, I've found that when the engineers designed these boats, they had user safety, theft and engine damage thought out to protect us from high repair cost. There are several sensors that can also keep you from getting engine turnover in the normal way........hope this helps.
