I don't belive it actually shorts to ground, more like shorts the phases across each other. The stator still produces power it just cycles around untill unshunted and connected back to the load.

getting there lol. Explains burnt stators, resistance in the circut (corrosion loose connectors, etc) must make the stator act like it is under a load at all times even when shunted. If the resistance is bad enough the load could easily pass 15 amps and never trip a fuse do to the load being in a unfused section. Heck bad enough the stator could be under a 30 or 40 amp load and smoke itself trying to 'keep up'

The issue with resistance at the output of the R/R is that it causes the regulator to over control and shunt the stator more than it should. That is because if there is excessive resistance (e.g. 0.5 ohms) there will be a large voltage drop at the output of the R/R.
For example If the R/R tries to push 10 amps and the 0.5 ohms is on the positive leg, then we are looking at a 5 volt drop. Since the battery is already at 12V+ then output of the R/R is at 17V + which will keep the R/R regulator circuit shunting causing the R/R and the stator to get hot.
The battery is not charging, and there is barely enough current going to the GS, because the R/R is constantly shunting current in the stator.Last edited by posplayr; 10-29-2010, 11:07 AM.

Question
I'm measuring the current drain on my battery in series between the positive battery terminal. My meter is set to 200m
My reading is 10.2.. Is this .102 amps or .0102 amps?
Any ideas

Your display shows 10.2, so that is 10.2 miliamps, or 0.0102 amps.
