I have a 20kw generac standby generator, where the starter tries to engage after the generator starts up and is running. Only has 316 running hours. Installed new starter in 2016.

For the over voltage there is an adjustment on the control board.
Should be tested with a load something plugged in.
The hertz might just come on when under load and adjusted too.
If you need more give a model number and whether it is 13kw or 40kw.

Generac Model 5525-1 20kw air cooled standby generator Question: How do you access the battery? I think it is behind the front panel, but can't readily see how to open/remove the front panel. Thanks!

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.

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.

Generac EPS-15 attempts to engage the starter while running

I work on these everyday. You most likely have a bad rotor or stater if the starter engages while running and no output. The no out put is making the generator think its not running causing it to try and start. If its not that then its the control board or voltage regulator.

The starter pinion drive gear is sticking.... its the smaller gear on the shaft that moves up and down to engage the flywheel gear and start the motor. Carefully put a LITTLE hi temp grease on the shift splines (curved ones) and see how much that helps. The gear is not staying "retracted"..if this doesn't help.. the spring that pushes the gear back down may not be strong enough...(you could always fix both)

Thanks Steve for your quick response, I'll give that a look-see, something simple I hope. I should have mentioned it tries to engage about every 10 seconds after the engine has started. Its not a contiueous contact sound, just a quick contact,a sparking, then repeat. Like its getting a signal to re-start?
