My generac generator came on and there is no power outage. It has a solid green light but seems hot

If you have a Generac Generator which fails to start during a power outage and gives an Error Code 1518 - RPM Sense Loss you can try and manually get the generator restarted very simply. ... The generator should wait 5 seconds and then try and auto-start up to 3 times.

The current models of automatic standby generators will have LED indicator lights on the side compartment of the generator. A green LED light will indicate that the unit is in AUTO mode and is ready to run, or is running properly during a utility outage. The yellow LED light will indicate that maintenance is needed. The red LED will indicate either that the unit is switched to OFF or that there is an alarm detected. If a yellow or red LED are present, you will need to check the generator's control panel, as it will describe the type of maintenance needed or the alarm present. This information can be found in the owner's manual as well. You can find a copy of the owner's manual online by searching the model or serial number of the unit here

Check the connections to the commercial power sensing unit. Sounds like it may have a bad connection to the ATS. (Automatic Transfer Switch). Generac Power Systems The best backup generator for your home business...

its possible the overspeed is set to sensitive. or your rpm are to high. these are preset in the factory as a safety, check your manual to ensure your rpm speed is in the pre set area. generators will do this under load when you have a big load on them or take a load off. the governor will some times over compensate causing it to trip on overspeed.

batteries only last about 3 months on these units. make sure you are within 20 ft of the generator and put in new batteries. The green light will blink is a minute or so.

These tires are made of a hard plastic with thick sidewalls to hold the generator up. They are not repairable once the sidewalls break down and collapse. The only option is to replace them. If you're still under warranty you can get them replaced under that. Only problem is you'll get the same kind of tires, unless Generac has updated them, and have the same problem in another five to six months. Your best bet is to do some research and find some truly pneumatic or solid/foam filled tires for your generator.

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!
