Engine pulsating/ electrical pulsating off/on

[Guest]

Hi , here's my situation. I rode about a mile to the gas station, filled up then while leaving my 1980 gs850g began to lose power and pulsate off, then on, off then on until I had to pull over. When cranked the throttle it would bog out and stall. I turned it off then turned the key to on but had no power. I tried it a few more times then the power came back. I started it but with the same pulsating. I waited about 10 min then it started and seemed fine , drove home and it seemed ok until I checked with my volt meter that the battery was not charging. Is it my stator or rectifier? Battery is new.

I'd start here, http://www.thegsresources.com/statorpapers3.php seems like our bikes have stator issues. The starting page is here incase you need to move about the document http://www.thegsresources.com/statorpapers.php

Could be one or both or neither, thoughly check and clean all the joints/bullets in the charging system and do a fuse box clean and then check if your charging and at what rate and post the results.
when you have cleaned and checked all the joints and are not charging then do as the below post recommends and follow the stator pages to diagnose the problem.
