Rectifier and/or stator bit the dust. DC voltage goes down on rectifier red lead to ground when running. Rectifier has 4 leads red, yellow/blue, yellow/grey, and yellow. Tried to measure AC voltage on the yellow leads in various combinations. Nothing above ~2volts. Can I test the stator with an ohmeter and what readings should I look for. I'll check the rectifier this weekend. Boats located 265 miles from current location. <br /><br />Thanks,<br />John<br />^Bump

If it's that far away, I'd take a shop manual. <br /> ;) <br /><br />c/6<br /><br />Hooty

Understand we should buy a repair manual. Given that we don't have one any suggestions for quick and dirty troubleshoot?

Anybody willing to help? My Dad's carrying around two batteries and doesn't seem inclined to buy a repair manual
