97 Challenger 787 Electrical Help

[Prime Power]

Hello, my boat has a new engine installed last year. I started it up today just fine, however almost all the electrical is not working. The lights, the blower, oil and fuel levels. The gauges light up, but the needles do not move even though there is fuel and oil. I checked fuses, the blower one was burnt. I replaced it but still nothing. Any help is appreciated. The engine runs fine.

Are all the fuse locations in the front power distribution board under the storage bin without 12VDC? The main fuse is in the rear e-box on the circuit that supplies that front power board, make sure that blower is switched off if you find that's dead blower motor windings are likely shot drawing to many amps.

Running to or from the battery switch there are fuses as well. Check them.

The fuse you're looking for is circled in red right up by the main harness connector in the picture.

1st off thanks you all for your help. What I thought was one problem is what I believe now to be three. The fuel sensor has gone, the blower motor is only showing .2 ohms and the nav light is burnt. I can only afford the light, ha. On to look for some parts. Thank you
