I had made a drawing of the AH wiring which might help anyone still confused with the imbalance. It is attached
My two cents worth from 40 plus years of generator sets. when replacing a radiator , flush first to remove any residue left from soldering and cleaning. second, always use fresh coolant and mix to 50/50 using distilled water (RO works but the glycol suppliers insist on distilled) . Include an additive to control Ph and other chemical imbalances.
The fan: Squirrel cage fans consume the most horsepower un-restricted. As you restrict the air flow (by closing the enclosure for example) the current flow reduces. Check it for yourself with a clamp on ammeter! Most of these motors have thermal limits built in (hence "thermally protected") so when the load goes up so does the current and the windings get hot, BAM down she goes! The one thing I wish Newell would incorporate is an air flow switch so if the air flow stopped the set would shut down.
End of 2 cents worth!!
