Re: 1972 50hp - 50ESL72c
The stator supplies separate voltages to the ignition and charging systems. If you lose battery voltage the motor will still run, but you won't be able to start it (without a rope) and eventually you'll lose the ability to shift. The good news is that it will shift to forward and stay there until the battery voltage is sufficient to pull it back out of gear (or all the way back to reverse). Neutral is achieved by supplying 12v to the green shift wire. Reverse is achieved by supplying 12v to both the green and blue wires. That way if the shift electricity fails, the gearcase is automatically in Forward.<br /><br />Sounds like you definately need a stator. There should be continuity between the yellow leads but none to ground. Sounds like yours has shorted to ground. But you'll get readings like that if the leads are still connected to the rectifier. Make sure they are not connected to anything when you test them.<br /><br />The demand from the shift solenoids isn't huge, but it is there. I wouldn't be suprised if a fully charged battery in decent condition lasted a whole day without a problem. Starting would be my biggest concern the longer the motor is in use.
