Re: 225 evinrude NO SPARK (All Cylinders)
Its optical ignition then, ok, try doing the tests per Bill Kelly at Mastertech.
I found my problem by following these tests.
This approach eliminates the need for the specialized ignition box used by factory trained techs.
some basic tests.
Check the kill lanyard and key-switch position.
Verify the engine rotation (The engine needs to be turning in a clockwise direction).
Check the power pack and ignition coil ground wires for corrosion and tightness.
Connect a spark gap tester to all cylinders.
Disconnect the boat side harness and connect a remote starter unit. Check for spark. If the engine has spark, check the boat side harness's black/yellow wire for shorts to ground.
Disconnect the 5-pin connector on the port side of the power pack and see if the spark returns. If it does, use the fluke meter set to ohms and see if the black/yellow wires are shorted to engine ground.
Check the battery voltage on the yellow/red striped wire while cranking the engine. If below 11 volts, charge the battery or check all battery cables.
Remove the sensor wheel and check for damage, especially where the top slots are located. Sometimes the wheels will break out where the windows overlap.
Check the sensor eyes for dirt, grease and the like. If you need to clean it, use denatured alcohol and a Q-tip. Do not use any other cleaning agent because damage to the optical lens will occur.
Disconnect the voltage regulator/rectifier and retest. If the engine now has spark, replace the regulator/rectifier.
