Confussed

I have a 81 flhs shovelhead, my inner primary was jumping ,found out after taking outer primary off that 4 or 5 bolts were hand tight , 2 or 3 were kinda tight and only 2 were fully tight. I took off clutches, primary chain, compensating sproket, the whole 9 yards, I then took each bolt one at a time cleaned them put on locktight and reinstalled . got every thing back together, bike started great, idled great , ran great when I reved it up.As soon as I put it in gear and tried to take off it sputtered and died, try to restart it and it acted like the battery was dead, pushed it in shop and hooked up trickle charger and just for the hell of it hit start button started right up, let it run for a few min. seemed like all was great, as soon as I put it in gear and tried to ride it spit and sputtered and I got about 500 feet and it died.A friend put a meter on battery and it read 11.8 volts when it was reved up and he said it was the rectifer. The head light comes on with the ignition switch and burns bright , so the only differance between running great and spitting and sputtering and not running is when you put it in gear and try to move, I am baffled any input would be greatly appreciated

the book says there is no test for the regulator/rectifer you have to replace with a known good one, and thats what I think it is but I didnt know if there was a differant load from being out of gear and being in gear ?

Battery should be charging a little over 14 volts. Bad regulator/rectifier I'm thinking.
