Re: Yamaha EF1000 Will only idle and produce 12VAC
My guess would be that some failsafe is in action here. It is possible that either a fuse OR the breaker is bad, or is not resetting in the case of the breaker button. Yamaha likes to idiot proof these things. Some of them disable the sparkplug if the oil gets low. Forget about just a warning light.

it seems to be the standard that the rating or model ??1000 or ??1500 or ??2500 or ??5000 or??5500 or ??6500 is the kv rating of the gen-set regardless of straight or inverter
so if yours is EF1000 it will be 1000 watts or 1 kv
remember that most electric drills are 1000 watt units so a unit this small is mostly good for lights, charging batteries, small compressors for tyres
clean tank fuel lines air filter and completely clean all carb parts and jets just did mine runs mint now did the same thing i also put in a new spark plug changed the oil a good once over goes a long way just take your time use a good carb cleaner like crc or gumout and check the jets they have small holes on the sides that can clog up hope this helps

Hi, I have the same generator and I pull the load and it is fine. The engine RPM is controlled by the
governor. The voltage will not come up until the RPM is at full. First see what the RPM problem is and then check the voltage. Open the cover and look to see if the carb linkage is hooked up , if it is you mite have carb problem and address that first. Hope that helps.
