’ve got a Sea Ray 2007 Sundeck 240 w 350 mag mpi engine/bravo3 outdrive. ECM module is 0501, engine SN is OW665845 with a 14 pin harness. I had the 20 amp fuse blow between pins H and G. This happened right after I launched off the trailer, so the engine was really even warmed up.
With the fuse blown it wouldn’t crank. When I replaced the fuse it started right back up and it’s run fine now for about an hour.
Using the ECM diagnostic manual, I was able to determine there is a red purple wire that comes off the fifty amp circuit breaker and goes to pin H on the fuse holder. Pin G is on the other side of the fuse, and the pink purple wire coming off there goes to pin A on the CAN connector and pin A on the 14 pin harness. I don’t have a set of wiring diagrams so I can’t go much further.
