1990 150 charging issues

[drodkey]

First thanks for all the great information and help. I searched previous post but could not locate anything. I have a 1990 Johnson 150 that doesn't seem to be providing any charge. When testing the battery connection I get a reading of 12.2 volts before starting the motor. While idling and higher rpms I still read 12.2 at the battery. This is a dedicated starting battery just to my main motor. Can you help direct me towards testing procedures on the rectifier - regulator. I have ordered a new manual (not selco) but hoping to address this while waiting for its arrival.

does your tach work ?

Yes the tech works.

ok check the red wire going off your Rec/REG and see if you are getting 13.8 or higher that is connected to your starter solenoid.Also you should have a small fuse on the same red wire

Okay so got back out to the boat today and the tach does not work. Question I have is I found the regulator underneath the fly wheel. Any tips or cautions in removing the fly wheel to replace the regulator?
