What options exist for -12 installation in a J3. What I mean is a full -12 installation. If I put a Generator or Alternator on the -12 case the exhaust becomes challenging. Yes I know most people don't install engine driven electrical systems, yes I know light is good, simple is good Light is really really really good. I get it. What I'm looking for is a hint, a clue or maybe even hard data on an "approved" " sort of approved " or seen once in a dark hangar exhaust system that clears the generator / alternator. I'm not concerned with oil screen access. Thanks to all in advance. This really is a great forum. Tom
