phatmanmike and jtexas i purchaced a new rectfier today (and tried to get a manual said it would take 3 days to a week go figure have part no book) well changed it and still same problem it wont read any higher than 12.86 but it will hold its own if you turn on lights it will stay at that voltage well at least for a half hour or so but its not puting out any more than that. i do know that the rectifier converts ac to dc but when testing the legs on the new rectifier i get 6.2 volts on the red to the batt 12.86 on one of the yellow from the reftifer and nothing on the the second yellow leg from the rectifier nothing in ac or dc i know that it showed continuity between the two legs , wondering if it could be the stator.did a visual check on all wires (even pulled flywheel) they all look good no weather check at all pulled plug on harness not a bit of corosion. i know the engine is older but it has very very little hours on it. i did order the book but any info now would be greatlly app
