You need to press down on the top lid as you unlock. This... from a girl who knows!

With the engine off, check the exciter brushes and slip rings which supply magnetic power for the alternator winding in the stator. Also, check the motor-to-alternator mechanical coupling. Check the breakers for tripping. To service beyond this point requires a schematic of the alternator, a voltmeter, plus knowledge of what the schematic is telling you. Good luck!

All internal combustion engines have the same requirements. They must have the correct air fuel mixture and source of ignition in order to run. Although I am unfamiliar with the system you have, the fact thst it will start without the air filter but won't with the air filter indicates that you either have a dirty air filter (you said yours was clean) or you have too much fuel entering the combustion chamber. Beyond that I would only be guessing the reason (air fuel mixture regulator, worn jet, wrong size jet, something else bocking air flow etc.)

The flywheel side or the PTO side? In either case you need to disassemble the unit to get at the end and then use a hook to pull the seal out.

2 bolts on top of the front panel. Take them out and then just puul up and it come off. you can then easily remove the battery but make sure the leads dont touch as they still have charger power running through them.

Hello, an interesting question. I am not sure what your local codes state, for myself to prevent any ground currents, I would pull a #6 ground as a minimum and not install a ground post. Like I mentioned above, your local codes may or may not require a post. Be sure that you connect the ground from the generator securely to the existing ground in your existing ground system.

This 2099 has disabled my Generac after being fine for 2 yrs???

I had a similar problem and it was because I had OVERFILLED the oil! I drained enough to make sure it was within the crosshatched markings on the dipstick and it started right up.

It sounds like the coil has went bad, replace the coil and you should be good to go

It sounds as though there is an issue with the carburetor. If the unit is "surging" with no load I would recommend thoroughly cleaning the carb. It would also be a good idea to test the fuel pump. Per Generac you need to disconnect the fuel line leading to the carb and pull the starter rope over to see if adequate fuel is flowing. If none of this is the issue try testing the stepper motor on top of the carb. If you unclip the wire and use an OHM meter all wires should test at 150 ohms. to test place on test lead on the blue wire and move the other lead to the remaining four wires. The should all ohm out to roughly 150ohms. if this is not the case you need to replace the stepper motor.... Before you do any of this you should check for fresh fuel, a good spark plug, and proper compression.
