Re: 90 Evinrude-Not Charging
DJohns.... The ignition switch shouldn't bother the charging system as the red (charging to battery) wire of the rectifier leads directly (via the terminal block) to the battery post of the starter solenoid.<br /><br />The stator, if memory serves me correctly should read 560 ohms plus/minus 75 ohms between the yellow yellow/gray wires.... and zero ohms between either of those wires and ground. Apparently from what you've said, those readings hold true.<br /><br />No offense intended, but just in case the readings were taken wrong on the rectifier (it happens), the procedure follows.<br /><br />(Small Rectifier Test)<br /> <br />Remove the rectifier wires from the terminal block. Using a ohm meter, connect the black lead of the ohm meter to the rectifier base (ground), then one by one, connect the red lead of the ohm meter to the yellow, yellow/gray, then the red wire (some rectifiers may also have a yellow/blue wire. If so connect to that also). Now, reverse the ohm meter leads and check those same wires again. You should get a reading in one direction, and none at all in the other direction. <br /><br />Now, connect the black lead of the ohm meter to the red wire. One by one, connect the red lead of the ohm meter to the yellow, yellow/gray, and if present, the yellow/blue wire. Then reverse the leads, checking the wires again. Once more, you should get a reading in one direction and none in the other. <br /><br />Note that the reading obtained from the red rectifier wire will be lower then what is obtained from the other wires. <br /><br />Any deviation from the "Reading", "No Reading" as above indicates a faulty rectifier.
