Sea Fire module question

Makes sense. Notice the printing of that is lighter and thinner than the rest of the schematic. Like it was added to the drawing later.

I suspect that is the ignition power for the electronic shift and throttle controls.

Figured them out by disconnecting them. 787 and 788 are the engine ignition feeds to the system monitor for it to tell when the engines are running. 323 and 319 respectively on the system monitor schematic. If they aren’t connected there are no engine alarms.

Sea Ray schematics are usually pretty accurate...sounds like a miss on this one.

There is a possibility that wires 787 and 788 do feed something other than the Systems Monitor directly.
The Systems Monitor wires 319 and 323 may tap off of wherever 787 and 788 terminate.

Did you actually see 787 and 788 printed on the wires at the SR Monitor input module?

No. 319 and 323 are printed where they enter the control module. You know, I forgot to try the electronic shifters. I’ll try that tomorrow. I’ll see if I can physically trace the two wires as well.
