what should my charging rate be?

Re: what should my charging rate be?

Ok..so, fully charged battery....12.7 volts. I did my ohms test again for the rectifier. I actually got readings on BOTH directions on a NEW rectifier hooked up exactly by the book (shop manual specifically for my engine). I ignored that and tested the stator. I got a reading of 2.5 mega ohms (spec. is .8-1.2 ohms- I didn't do the conversion). Anyway, I fired the engine up, DVOM still connected to battery, and "fast idled" motor to about 1,500 rpm....ish. Watched DVOM climb rather quickly to max out at 15.01 volts at battery. I'm assuming this means my stator and rectifier are working properly together. Starting out at 12.7 volts, key on, engine off, volts drop to 11.2 during cranking, back up to 12.7 almost immediately, raise fast idle to 1500 rpm, watch DVOM and *poof*, 15.01 volts within 30 seconds. I think that means I'm good on charging. Anyone have any input? Thanks

I'd say it is just fine, in spite of these false tests. The one that counts is the 15V at fast idle. The system is working.

Many (most) DVOMs won't test a diode. Mine won't. Without getting into a long discussion on how the atoms in a diode work, just accept it. I'll bet if you throw an old cheap analog VOM on it it will show good.

I just don't believe the 2.5 Megohms reading either. Something is fishy there.
