Good call going to a SERIES R/R (e.g. SH-775). Remember any test you do with an ohmmeter (or diode tester) is a NO LOAD TEST. So if it fails fine probably bad. If it passes don't assume it is good. The jumping voltage while running is surely the R/R unless for some reason your meter is wonkers. The VAC leg to leg tests are supposed to all be at 5000 RPM and measure over about 65 VAC with 80VAC being the typical value. Additional tests are to test leg to ground also at 5K RPM and you should see ZERO VAC ; the stator should be isolated from chassis and engine! You could do the test with an ohmmeter producing a powerful 3V :). But if there is 80VAC on the stator that is a much higher voltage the stators insulation must withstand to keep from picking up voltage on ground.

The easiest thing to do is a "Quick Test" and it is located over at GS Resources unless I can get it posted here as well. If you post the numbers I can steer you in the right way. http://www.thegsresources.com/_forum/showthread.php?164993-Charging-System-QUICK-TEST&p=1272192#post1272192 The voltages you provided are possibly OK, they are normally measured at 5000 RPM and you should have about 80 VAC. If I scale up your 35VAC (5000/2000) you are at 87.5VAC which would be OK if you can really get it. best not to jump to conclusions and see what the Quick Tests says. Also I will forewarn you there has been a quite revolution going on in UJM's converting away from SHUNt R?R's to SERIES R?R. That Electrosport is one of the dreaded SHUNT R/R. They cook stators.
