Looking at an Evinrude 9.9 hp model #10755A. I believe it is 1977 w/electric start. Does the electric start mean it has an alternator for charging also?<br /><br />Thanks
1977 is correct: 9.9HP <br />Rectifier on this model is not necessary for starting or running so you may not find it installed. Your battery will naturally not recharge. I have a 15HP electric start with no rectifier.
The magneto must have a charging coil in it to produce charging current .There are diodes in a rectifier that let the current only flow one way giving the needed 12 volts to the battery. nevjb
