Re: Evinrude 200hp voltage????
Put the voltage check aside for the moment and check for spark.<br /><br />Remove the spark plugs. Rig up a spark tetser whereas you can set a 7/16" gap. Crank the engine over and observe. The spark should jump that gap with a strong blue lightning like flame.... a real SNAP!<br /><br />If not, disconnect the instrument wiring harness from the engine so that the ignition switch etc is not attached to the engine electrical system.<br /><br />Now, crank the engine by using a small jumper wire from the battery side of the starter solenoid to the small 3/8" nut that energized the solenoid/starter (not the 3/8" ground nut)<br /><br />If you now have the proper spark, in all probability the ignition switch is shorted, in which case, replace it.<br /><br />If still no spark, look closely at the stator under the flywheel. The large black coils that you see at the rear portion of the stator (usually at the rear area) provide approximately 300v AC voltage to the powerpack. Should they be cracked and/or melting down a sticky substance on the timer base and block, replace the stator.<br /><br />The stator is a two fold component. The small coils provide AC voltage to the rectifier which converts that AC to DC voltage in order to charge the battery. The large coils provide voltage as mentioned above to the powerpack.<br /><br />When the large coils melt down (never ending problem), the voltage to the powerpack drops which results in erratic and eventually no ignition. Let us know what you find.<br /><br />Spark Tester - Home Made<br />(J. Reeves)<br /> <br />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.<br /><br />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:<br /><br /><br />..........X1..........X2<br /><br />.................X..(grd)<br /><br />..........X3..........X4
