Honda Generator Help Low voltage at Idle
I have a Honda EX1000. It does not I’ll put enough voltage at idle around 8.5 V. If you manually increase the RPMs the voltage will read properly. Anytime I Plug Something in it Will Not Automatical...

Every inverter genny, Honda, Yamaha, Champion, even the Harbor Freight Predator, uses an electronic throttle control to control throttle plate position. There is no idle screw like a conventional carb, throttle position is electronically controlled by the regulator which sends a signal voltage to the carb. On top of the carb, attached to the throttle plate arm is what is essentially a stepper motor and that sets the engine speed according to what the regulator tells it to.
When you run the unit in normal mode, the regulator tells the stepper motor to open the throttle to it's high speed position. In economy mode, the throttle is closed until the regulator senses a load and then it tells ther stepper motor to open the throttle plate to compensate for the load.
Not sure about a Honda, but a with a Yamaha (which is essentially the same (Yamaha holds the patents on the design and Honda uses Yamaha's technology), you can reset the stepper motor by disconnecting the molex connector, manually opening the throttle plate all the way (t you have to remove the air cleaner so you can access the throttle plate and open it up with a slim object (pencil works well) and with the throttle plate held open, replug the connector and keep the throttle plate open and start the engine. As the engine picks up rpm, release the plate. That resets the stepper motor. Thats how you reset a Yamaha.
If it don't reset and resume normal operation, the stepper motor is bad and needs replaced. Yamaha's are around 50 bucks, I presume the Honda unit is about the same or you can buy a complete carb for about 150 bucks. The stepper motor secures to the top of the carb with 2 phillips head screws and nad a spring inside. Don't loose the spring. The replacement stepper motors don't come with a spring.
The is no user adjustments on any of the carbs. It's all electronically controlled.
All inverters use a multi pole head that makes DC current which is electronically rectified and excited to 60hz.
Why they cost more than a conventional 3600 rpm 2 pole ac generator that relies on constant rpm to produce 60hz. An inverter does not. It inverts the dc to ac and excites the ac output to 60hz.
I have a Yamaha shop manual. You can download the shop manual from the net. Not sure if Honda has the same option but both are very similar.
