Well I cycled it very deeply today with no sign of engine trouble. I drove 70-75 miles on a single charge (a lot of EOC time). As I neared home the voltage meter read 10.8 sometimes when the engine was on, but would jump back to 11.3 during EOC. I only did that to test max range. I do not intend to run the batt down like that often. I am optimistic that this mod will yield my highest tank yet, despite being deployed late in the tank. Will be fueling in two or three days and will know then.

Thanks, brucepick, for the tips about the alt... I wil check out my setup. I think this might be an HX advantage. My DX alt seemed always to be charging.

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.
