1987 140 johnson charging problem

[bevdog]

My electrical charging system keeps droping out. It works first start 14volts, then when it warms up it stops and goes back to battery voltage 12.5V. I wanted to check the resistance of the stator but am unsure of the reading I should see...any ideas?

Yes I recommend a service manual for the proper proceedure and readings. Unfortunately I cannot provide that for you. The following link should assist you.
