Cptnvideo - as 3Tons said, better than I did, my Magnum sees the genny as a defective power source because of the milliseconds of voltage droop when it becomes loaded. I have started the ACs on batteries and hoped the genny would take over. Unfortunately the Magnum takes a few second ms to qualify the new source, then when it tries to bring it in the genny voltage drops instantaneously and the Magnum kicks it out. If I run into this next time I might try limiting genny power to 15A, or 10A etc to see if that allows it to provide most of the power without significantly dropping. We’ll see.
3Tons - thanks, I’ve thought about just putting a Magnum bypass in to allow direct running of AC from genny. I think your solution is more elegant. Still I haven’t given up with futzing with current hardware instead of adding more…. Frankly not sure if I had spent more on a Honda I might not have been aware of this idiosyncrasy. Not sure if I’ll keep messing around or maybe make a hardware change…
