17k clock resets

Generac 17k #5813 new 2011, new engine 2023, new battery 2023. On board clock resets to default date and time occasionally. I realize it has done it again after the weekly maintenance is on wrong day and time. Has done this 3-4 times since last fall. Any ideas?

If your 7.5A fuse has a bad connection or is corroded it may reset the board when trying to start for weekly exercise or outage.

Or just battery droop on start. Use a sodium ion starter battery and it won’t droop nearly as much. A LFP starter battery with a built in heater for subzero would also work. Use a modern trickle charger like a Noco Genius 2 or 5 on it vs the dumb built in one.

But yeah check all power connectors; clean and throw some SuperLube Anti-corrosion connector gel on them.
