Re: 115 hp evinrude rectifier replacement 1979
Thanks for the help all. This cdi part has been identified to replace the bad rectifier i have currently. i was shocked to see that it did not have the same color scheme as the one that needs to be replaced. It looks like ezeke knows his stuff, so i will take his word for it. i will hook up the red with red, and whatever yellow wire on the new one with the yellow and yellow/gray wire.
my trouble was that my tach was not working. i read the forums and saw that problems usually lie with a bad rectifier. before installing the replacement, the tach all of a sudden started to work fine. the next test i ran was to see if i was getting a charge on my battery when running above 3500rpm. i did not see any charge imposed on the battery.
the next test i ran was a diode check on the rectifier and i believe i uncovered the problem there. i had a lead to ground and the other to the yellow. one way i had high ohm reading, then with switching the leads I had a low ohm reading. then, i tried this test on the ground to yellow/gray wire and got no readings at all each way. and the same thing when connecting the leads between yellow and yellow/gray.
so i think that backs up the rectifier being bad. any thoughts?
nick - thanks for the offer. i will hook this up and if i have any problems, i will get in touch about pix. let me know how you waterpump replacement works out. i will probably have to do that too at somepoint, maybe over the winter....
