The G1 Insight and HCH1 can be bypassed by turning the master off and unplugging certain connector(s) from the BCM/MCM; however, the HCH2 is a different beast. On both of my '06, I could bypass it simply by flipping the master switch off. I would get 12V charging between 1500 and 3500 rpm or so. I maintained confidence in the 12V state by running a voltmeter in the cigarette lighter port.

Others have reported this DOESN'T work for them on other years, and their 12V is run flat. I know of no other way to bypass it on an HCH2.

The concern with bypass is retaining 12V charging. It's worth experimenting. One could also mount an alternator. I think somebody did it on this forum or over at Greenhybrid. It wasn't pretty, but it worked.
