Is this stator bad?

Beforemeasuring the stator resistance touch the leads together real tight and see what the meter reads. Usually they read .2 to .8 ohms. This should be subtracted from the values you get.

I think your readings are a bit high, indicating some extra resistance on the legs. But the real test is when the bike is running, If you get 60 -85 volts it's good enough. Some get even more, like 100 a leg.

But since it's on the bench I would replace it and keep this one as a spare. Even new stators are defective or short lived sometimes. I travel with a spare stator just in case, Earlfor's sad tale of tractor batteries and chargers convinced me to be prepared.

I guess I missed that story.

However, the previous owner of my Wing earned the name "Deep Cycle" on the last day of a vacation trip several years ago. The alternator failed about 200 or so miles from home, so he stopped at a Wal-Mart, bought a deep-cycle marine battery and some jumper cables. He put the battery in the cooler on the tongue of the trailer, ran the cables up to the battery and pulled the headlight fuse. He made it home with no problem, but got the name. To avoid future problems, he installed an alternator with slightly higher output and a better reputation. Stock output is 40-45 amps, depending on which literature you believe, the new alternator puts out 90 amps.

Okay, I just did this and I got a reading of 1-1.5 ohms, so if I subtract that from my original readings, then I am within spec. Yes I know that 1.5 ohms is kind of high, but I'm using a cheap DMM with homemade leads. Right now I just want to get this engine running to see if it actually works so I'm gonna leave it in there for now and focus my attention on the carbs. Thanks to all that replied.
