Dead Mercruiser Help Please

[Salty Dog]

I have an 84 Sea Ray with twin 488 Mercruiser I/O in it. The port one starts and runs fine. The starbord one suddely is completely dead. There is no power to the guages or anything else. I checked the circuit breaker and main harness and they are fine. Any suggestions on where to start? Thanks

Dead battery ?<br />Broken wire ?<br />Bad relays/ solenoids ?<br />Dead short ?<br /><br />Start at the battery, then follow the circuits through.... Shake,wiggle,test, till you find the problem.....

There is more than one circuit breaker/fuse...check your wiring runs carefully. Also, is there a kill switch wired in??
