Without really controlled ABA testing, you really can't know for sure the results. You'll want weather, road, temp, throttle, speed, and route conditions all to be the same at minimum. Then there is the state of how warm the engine and tires are... the slightest changes in your throttling--imperceptible to the driver--will alter results. I hope by "the hot wire" you don't mean the alt's output wire to the battery... somebody here wrecked an alt that way, fried it, IIRC.

Sorry for the bummer... keep up the efforts... some work some don't, you know? Good luck!

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
