Do I need a new stator coil? ('90 Max with 60k)

I read about 12.5 volts at 2200 rpms at my battery. According to the manual; over 15.0 volts means a new R/R and under 13 Volts means new stator. Stator coil resistance is 0.7 ohns. The manuals says a max of 0.48. I cleaned the connections to the stator. The connector was hot when I disconnected it. I don't want to drop a lot of $$$ for a stator if I don't have to. (Battery is healthy and holds a charge) Advice please

One quick way to tell with your stator is to look for discolored varnish on the coils. If you see a coil that is much darker than the others you probably have one leg of the stator that is bad so it needs replaced. With the resistance being a bit high you will lose voltage as well.

Thanks Jim, that is a good idea. I'll try it tomorrow. I haven't look at the stator but I read 0.7 ohms all the way around. Maybe a good cleaning will help lower the resistance. I'll post the results. Rich.

That 3-wire connector is a major source of resistance in the charging system!
i'd solder the connections, and run without the plug. The stator is 3-phase AC, so you can connect the wires up in any combination. Just be sure to insulate them well from each other as well as from ground. Make sure you do a good job soldering them, too...

For what it's worth, my original stator died at about 60K... The new one's going strong at 120K+.

Thanks for solder comments. At one point the white plug coming from the stator melted and I have been plugging the three leads in separately for a while. I guess that is an indication of over heating. I pulled the stator and half of the coils are dark and some of them have material connecting them. The other half of the coils of bright and clean. I think I have to bite the bullet and get a replacement. Any advice of a source. There are two places on Ebay selling replacements for about $130 each. Rich.

I figure it's time to post my results. Yes the stator was bad. I found a rebuilt stator on Ebay for $79.95 with trade-in. The seller is timparrott316 . I have had it installed and working for almost two months. It is doing the job, putting up plenty of voltage. No more slow grind when the engine is hot.

I have a similar issue. My stator ohms out at the lower limit of what the manual says is acceptable -- about 0.36 ohms on each coil. The strange thing is that the voltage will go up to slightly over 13 volts when idling at about 1000 RPM, but will go DOWN when I rev it higher, to the low 12's. The rectifier diodes all check out good with a diode tester. The battery is a fairly new Odyssey AGM and takes a charge well from a battery charger. I've used contact cleaner on the plug contacts, no change. It usually charges up fine with normal usage, just the last couple of weeks has had problems. I haven't pulled the cover to check the windings yet, but hope to do that this weekend. In the meantime, if anybody has any ideas about why the voltage decreases when revved, I'd love to hear them.

I can't pull the stator off. It seems to be frozen in place. Ruined a 3prong clutch puller. Any ideas?
