This means that the entire Phase B tests in the stator pages may or may not be correct unless you replace your ohm meter with a MEGGER.
EDIT 7/7/2013:
I just discovered that there are several available for very reasonable prices on Ebay.
Old school:
Silver Tone Resistance Measurement Tester Megger
Digital :
VC60B+ Digital Insulation Resistance Tester Megger
Doing unloaded tests (ohm meter with small current) /open loop tests (OL voltage) do not test what happens at full current when insulation break down can occur. These VOM tests can only prove a bad stator, not confirm a good one.
If you have something called a MEGGER you can do an conclusive open loop test; watch this video it shows a good test using the MEGGER with a high power mode; and a failed test using a low power VOM mode. So with small voltage OHM test the insulation did not break down and the test gives the wrong result.
Since most people will not have a MEGGER, a good alternative but also definitive test is to test when the stator is producing full current and is shown to not break down the insulation using a AC current clamp. (i.e. measure stator leg current while running the engine at 5000 RPM)
You can now find cheap current clamps like the BK one below to do the test, you can test either the stator wire AC currents/voltages or you can also use it to measure DC output on the battery side of the R/R as well.
This is a BK model; there are some others for a similar price that have pretty descent specs if anybody is looking for an VOM upgrade.
There are others that are as good and perhaps even a little cheaper. Steve bought one for about $85 i think.
A quick tutorialon a clamping meter (for current measurements)
This is a tutorial for using a current clamp attachment but the same applies to the current clamp meter. The 3 phase AC is going to be very similar to a GS stator.
PS: A MEGGER is just a Ohm meter that uses a large voltage to test the resistance rather than a much smaller one like a VOM would.
Here are some MEGGERS for just under $400; the clamping meter is a whole lot cheaper
