2006 Rubicon, battery continues to go dead. Replaced battery and regulator / rectifier.
I'm trying to test the stator, I have the 5 pin plug near the rewind apart. I'm wondering if I should have the battery disconnected when checking continuity between the yellow stator wires and ground.
Also, how many AC volts should each leg (yellow wire) produce at idle and at high (5000) rpm?
When last I checked it made just over 20V on two legs and 15V on the third at high rpm. I know it should produce about 360W but I can't test that I don't think.
Any help appreciated.

What do you see for AC and DC voltages at the battery with the throttle at about half speed?

Hope for around 14.5 vdc and less than .5 volts AC. Anything much different than this indicates problems with the regulator / rectifier.

Best readings I can get at the battery is 13 volts half throttle. Turn on the headlights and it drops to 11.6. The RR is new.
Honda says there should be no continuity between the yellow stator wires and ground, but I do get an Ohm reading there. I am doing this test with the battery hooked up but I'm wondering if it should be disconnected for this test. The service manual does not specify.

When checking resistance of the stator windings the stator must by unplugged from the harness. If you are seeing continuity between the yellows and ground then ya probably got a stator problem and it will need to be replaced. Before you buy a stator make sure that those yellows are not bare or pinched by the case and shorting out.

Let us know what fixes it..?

Yes, I have the plug disconnected and testing between the yellow wires and ground. I will double check the wires for being pinched. Thanks for your reply.
