Switch generator to off. Remove 7.5A fuse. Disconnect Negative (-) battery terminal first and then Positive terminal (+). slide battery out the front (may be a tight fit) and install the new battery reversing removal steps. Connect (+) first and (-) last. Reinstall 7.5A fuse and switch to manual to start and test run.
SOURCE: my standby generator is just cranking but wont turn all the way
If it was installed only five months ago, it should still be under warranty. Call Home Depot and have them send out a repair person.
SOURCE: i have a 2.5 liter
Look for a fuse that protects a transformer that supplies the rotating field voltage. If fuse is blown, find a rectifier module that the transformer drives. Likely the rectifier has a shorted diode. Fix before replacing the fuse.
SOURCE: generac 20,000kW Standby generator doesn't start shows message STOP ALARM OVERCRANKED
Overcrank means that it tried to start and couldn't. It will go through 5 crank cycles and then stop with this alarm. Switch to off, hit enter to clear fault and then try to start in manual. Check to make sure you have fuel and pressure is 11 to 14 in WC.
how old is the battery? charge the battery then remove the negative cable place a test light between the battery and cable if the light is on you have a draw unplug things til the light goes out thats your draw
