Charging system suddenly quit.

Success! Thanks so much for all the help!

Decided to recheck the bulkhead connections yet again. Crimps still clean and tight and then.....

Wire J2 on the center bulkhead connection labeled N on the schematic breaks off at the crimp on the engine harness. OMG. Replaced the crimp and vroom, charges!

Thanks again you guys are great.

Now anybody know about a Geoflex geothermal furnace?
