We purchased a new Generac Stand-by liquid cooled generator, got installed by same certified electrician that did my neighbor's generator. The unit worked fine during testing, but failed to perform the weekly self-start. Upon inspection the panel, it was also blank - no power. We returned the NEW battery, got a NEW replacement, and the unit started right away. I inspected the panel a few days later, and it was emitting a "Check Battery" message. Called Generac South (a servicing dealer for our area), the technician came, but could not find the problem - claimed that it probably was a "vapor lock" that stopped the alternator from charging the battery. Does anyone else is experience this problem? Hondo
