CHARGING...AGAIN

[LongLine]

Charging again....

Anybody know what the ohm reading should be on a 75 hp evinrude (1984) between the diode/rectifier red and yellow leads? How about the red to yellow/gray??? Manual says yellow to engine ground should be infinite one way and have resistance the other. Same with yellow/gray to engine ground. It then says check yellow to red and yellow/gray to red but doesn't hint what the reading should be. Is it the same, or should they both be infinite, both ways???

(now I'm undercharging.)

Hey Tom,

I finally dug out my service manuals. Unfortunately they do not cover this model year. Wanted to reply to bump this topic up so one of the motor guys might reply. I did just have an undercharging problem (no charging actually) on my 9.9, and it turned out being the rectifier/regulator. I'm not sure what they used on your model. Those charging circuits are pretty simple. I bought the SELOC service manual for my motor and it has been pretty helpful.

Good luck.

Sponge - I've got a new rectifier diode, new stator, new battery cables and have gone back to a marine starting battery (also brand new) rather than the dual purpose marine battery. Also, cleaned and/or replaced a bunch of connections. Only thing left that I can figure is the flywheel. (which will be darn near impossible to replace) Will try again this weekend & see what happens. Wish me luck.
