Battery is critical, often overlooked. Before doing anything, check the trickle voltage to the battery, that's what keeps it charged between runs. Should be over 13v generally. If not, battery isn't getting charged to start the unit when needed. I've changed the standard clamp leads to marine grade terminals, cables are attached with lug ends, then sprayed with NOCO anti corrosion spray. When the unit is running, battery voltage should be over 14v, and yes battery should have full cell levels of distilled water. If you disconnect battery, Generac procedure is to remove 7.5 amp fuse at control unit, then disconnect white charge wire above the battery. After reconnecting battery, reconnect charge wire and insert 7.5 amp fuse. Then check all trickle and run voltages. May all sound like overkill, but the worst time to find out battery issues is when you lose primary power......

One tip, running the engine up to temperature before draining the oil will help with drain it faster/completely. Good diy video!

good video. change the setting on your camera so you are oriented properly. That way you are removing your filter instead of tightening it :)

The corrosion you see on the battery terminal, cost me $300 for a service call to my rental cabin. The Guy cleaned the terminals. That was expensive 10 minutes. I will put in a new AGM Group 35 4year battery, best price Walmart.

What about in between the annual service? We had ours run for 6 days after Beryl.

My 24kW does not allow me to reset maintenance.
