Re: Corm, Rectifier??

Hi DrRace,<br />Sorry I forgot about the red wire,it's been a long time.<br />The rectifier is coated with a high heat paint. Where it is burnt off is a sign of abuse or failure do to over heating.<br />It is a silicon rectifier that converts AC curent to DC current before it goes to the battery to charge it.<br />Test Method;<br />1) get out your VOM

<br />2)connect the red to the + rectifier tab and the blk lead to ground.<br />3)note reading<br />4)reverse leads<br />5)note reading<br />6)the ratio of the two readings should be <br />10:1 or larger.<br />7)hook the + & - test lead to each of the alternator tabs on the rectifier.<br />8) note reading<br />9) reverse leads<br />10)note readings<br />11)the ratio should be no more than 2:1<br />12) the true test is to check the out put at the battery with an amp meter while running the motor.<br />13) the output of this alternator is around 5 amps at WOT.<br />If it tests ok dont paint the fins as they will diapate heat much better,unless you ue it the salt. Then paint it.If I remember it was about a $20 option in the early "60s".<br />Because the ing is a magneto you don't have to have a battery to run it, just rope start it. It is nice to have it working as long as you have it.
