Need Help, my 2006 90 HP died returning to dock after several hours of afternoon fishing.
Turns over well, however will not fire. The four LEDS on the EMM do light during cranking.
The Diag software shows three errors log at what is believed the time of failure.
Code 81 cylinder # 1 ignition primary open circuit detected
Code 82 cylinder # 2 ignition primary open circuit detected
Code 83 cylinder # 3 ignition primary open circuit detected
I can find no spark (timing light) during cranking or with the static ignition test.
During cranking a snapshot with the the diag laptop tool shows
RPM =340 System Voltage=30 Ignition Voltage 292
From the Service manual the 30 volts looks correct for the RPMs indicated – not certain.
My question is an Ignition Voltage of 292 Volts looks a lot higher than the 200 V shown for running at normal rpms. 600 +
I have checked the path from the EMM to the coils and the coil resistance checks and they look good.
Any suggestions as to where to look from here would be much appreciated.
