I removed and discarded the computer screen and replaced it with a panel holding a single volt meter on the left and a machined pocket on the right where the face of the Marathon AVR can be accessed. Field wires are in the upper cabinet on the right side at the terminal block in the back right corner. I left the original AVR wires to retain the flash function and pulled the original AVR off the back plane and discarded it. L1 and L2 reference were grabbed at the contactor in the front left of the same cabinet. The contactor close toggle had been swapped years ago to a non-momentary and it now has its “close” output run directly to the contactor “x” terminal in order to bypass the last bit of the electronic dumpster fire above.

Seems content to make electricity without a single care now.

I re-routed the fuel return and now have a bulkhead fitting on the right side just behind the large engine access door for fuel return along with another bulkhead for fuel supply to the sub-base tank. I didn’t wait to see if the dumpster fire would fail to handle fuel delivery.

Nothing is controlled by the OEM electronics now. Still has the little blinking lights. Still useless.

Monsters Inc…. your silence is very reassuring….. lol

No…. the AVR is not in there. I ordered an SE350 and an analog volt meter. I will hopefully be out from under the influence of the electronics/computer dumpster fire soon.

The only redeeming quality of the OEM control scheme is its unwavering ability to devalue these generators so much for the secondary market.

Here’s another question…

Is the AVR still in this unit and the electronic dumpster fire above it is just disabling it? Did they leave the basic AVR in these units and just use the stuff up top to replace the rheostat and turn the unit ON/OFF?

If so…. boy that would likely be an easy UNdo, just like the electronic engine control UNdo…
