I've never noticed a fluctuation in voltage; it's always remained at 14.4v from what I recall. I wonder if running a 20% underdrive on the alt has affected the output behavior?
It seems the car already does it's best to reduce fuel consumption if it has the ELD, and even goes into high output mode when decelerating (according the the forum linked above).
Although I read a lot on how to bypass the ELD to run in high output mode, I'm still not any closer to figuring out how to disable the alternator. I figured I could put some massive switch in between the main output wire of the alternator. Any reason why I couldn't just disconnect the output?
I'm quickly loosing steam on this project since there doesn't seem to be a clear way to disable the alternator, and it's already efficient in the first place because of the ELD.
