My '82 GL1100 is not charging the battery. With the engine running I measure about 11.5V acrosss battery terminals no matter what RPM. I get 11.5V, 10V, 7V AC between yellow leads from alternator. That is with the alternator leads disconnected from anything else. Should read the same between all right?



I get .6 ohm between all yellow leads and no continuity to ground with any yellow lead.



Does this mean the dreaded stator replacement?



Your comments will be greatlyappreciated.

Should have more than 50 VAC between any two of the stator yellow leads.

If those voltages were measured with the engine running around 2500 rpm or higher the stator does look like it isn't operating correctly.

You should get a minimum of 50V AC from any two yellow wires. Also the voltage should not vary by a huge amount with any given pair.

I put an aftermarket stator in my wing that at idle is putting out 70-75 V AC on any pair. At 2500 rpm and above it puts out 90-95 V AC on any given pair. It's been in there for three years now, and I kept a real close eye on the regulator for the first year and a half and so far it has not over heated or failed.

The 1100s have a better stator setup than the 1200s which are notorious for stator failures. On an 1100 it's well worth just replacing it, on a 1200 it's often better to modify it with the external alternator.
