Cranked up to come in today and my SC gauge says "Lost Engine Com", left gauge (speedo). The backlight stays on on the right gauge (rpm), with a blank readout, main power switch off. Don't have a manual and really couldn't find any info on the Merc website.
Suggestions on where to begin?
Thanks in advance,
Brad
Disconnect all gauges, disconnect data harness at engine, disconnect terminating resistors. Inspect all connections for corrosion or loose pins.
Reconnect all connections, and retest. Let me know what you find!
