Hey All, I recently picked up a used pontoon that has a mid 80's Mercury 35hp. I haven't had it on the lake yet, but it seems to run well, but doesn't seem to charge the battery. Also, I have a brand new (deep cell) battery and when i try to start the motor, it only cranks a few times before the battery won't kick it over. I can pull it off a charger, crank the cold motor for 10 seconds, then it won't crank after that. If I put the jump starter on the battery it kicker over extremely well. Once the motor is warm, it starts very easily.
I tested the stator, and it seems okay. It has resistance (don't recall the number) and does not have continuity to ground. I replaced the rectifier and still can't get anything more than 12.5v or so at the battery, even at half throttle?
So looking for suggestions on where to go from here? I did clean every connection on the motor that I could find and am stumped.
