1992 Evinrude-no spark- not the kill switch

[jimmytee]

Any idea where to go next? I tried disconnecting the kill switch and still no spark....

Disconnect Black/yellow wire at the power pack and see if you get spark...

Couldn't really disconnect it as there are three other wires in that plug, so I cut it....still no spark...

Three Cylinder Engines
(Except Quick Start Models)
No Fire at All:
1. Disconnect the black/yellow kill wire and retest. If the engine's ignition has fire, the kill circuit has a fault-check
the key switch, harness and shift switch.
2. Disconnect the yellow wires from the stator to the rectifier and retest. If the ignition now fires, replace the
rectifier.
3. Check the stator resistance. You should read approximately 500 ohms from the brown wire to the brown/yellow
wire. (See DVA Charts).
4. Check the DVA output from the stator. You should have a reading of at least 150V or more from the brown
wire to the brown/yellow wire (while connected to the pack).
5. Check the cranking RPM. A cranking speed of less than 250-RPM will not allow the system to fire properly.
6. Check the timer base’s resistance from the white wire to the blue, green and purple wires. Reading should be
38-42 ohms.
7. Check the DVA output from the timer base. A reading of at least 0.5V or more from the white wire to the blue,
green and purple wires (while connected to the pack) is needed to fire the pack.
8. Check the cranking RPM. A cranking speed of less than 250-RPM will not allow the system to fire properly.

rickd gave you a pretty complete answer. What horsepower are you talking about?

The pins in the rubber connectors will push out and back in.... no need to cut wires.

Reconnect that black/yellow wire that you cut. Remove the spark plugs so that you will obtain the fastest cranking speed possible. Rig a spark tester whereas you can set a 7/16" gap. Home made rig follows.

Spark Tester - Home Made
(J. Reeves)

A spark tester can be made with a piece of 1x4 or 1x6, drive a couple nails through it, then bend the pointed ends at a right angle. You can then adjust the gap by simply twisting the nail(s). Solder a spark plug wire to one which you can connect to the spark plug boots, and a ground wire of some kind to the other to connect to the powerhead somewhere.

Using the above, one could easily build a spark tester whereas they could connect 2, 4, 6, or 8 cylinders all at one time. The ground nail being straight up, the others being bent, aimed at the ground nail. A typical 4 cylinder tester follows:


..........X1..........X2

.................X..(grd)

..........X3..........X4

Crank the engine by using a small jumper wire from the battery terminal of the starter solenoid to the small 3/8" hex nut that energizes it (Not the 3/8" hex ground terminal).

Reason for removing the plugs.... the engine must turn over at least 300 rpm in order for the stator to supply approximately 300 AC volts to the powerpack capacitor. A slow cranking engine would fail to supply that voltage.

With everything connected, I assume that you have no ignition (spark). disconnect that large RED electrical plug at the engine, then retest for spark using the jumper wire at the starter solenoid.

If still no spark, and the engine is cranking at the proper speed, look under the flywheel at the stator. If it is cracked and/or dripping a sticky substance down on the timer base and powerhead, replace it as in that condition the voltage to the powerpack will be insufficent.

If the stator is okay (and you're sure of that), and you still have no spark, in all probability the powerpack can be suspect.
