All I can say is "thank you." I went from grave concerns regarding 'codes' to actually changing out the battery. I didn't need to re-enter the panel information, but I did need to reset it by hitting "Off", then "Enter", and then "Auto". It all reset and then I started it through "Manual" to ensure it worked. All was perfect. Thanks for helping.

[@jamiller6843]

Just watched my gf flip out trying to take the whole thing apart bc couldnt find an Allen wrench the right size to unscrew the door that just lifts off...😂😂😂 I watched your video and looked like a genius lifting it off! I own a restaurant in the mountains of So Cal, with the fires burning everything and the electricity out everywhere. TY!!! We would have frozen tonight and I wouldnt have been able to open for business tomorrow ❤...P.S. i have never left a comment before on a KZbin video....But that's how grateful I am! 🙏 ❤

[@DIYSEMI]

well thank you. We wish you the best out there with what you are dealing with

[@libertyvilleguy2903]

Really helpful - I saved $150 in a service call by watching this. Much appreciated - merry Christmas 2023!

[@rytoniowendolini2793]

Most of them charge to do the battery and replacement separately too. I got quoted up to almost 400 by 3 different places to service it and that's not even the batter either. LOL. I laughed and said forget that. Will buy my own oil and get the kit off of Amazion.

[@tommybaldwin4675]

Thank you for the video. Was able to use your directions. The house I bought 2 years ago came with a 16KW generac generator and I have no clue what to do until I watched your video. Changed out the battery, corrected the time and adjusted the scheduled biweekly test time.

[@jabouletfiction8059]

Thank you! You taught me how to change the battery myself. I will be doing my own maintenance from now on. I super appreciate you KZbin guys.

[@stateniland]

5:07 it's always a good idea to wrap that neg. terminal in a rag... if it touches any metal parts inside that housing it will then be grounded once again..

[@thomashorn9152]

One of the link on here , you gave to someone. What type of battery to get. I clicked on it, gave a price of $460.00 boy that is a costly battery. Great job on the video 👍

[@mkowitz]

Just so you know, on a Generac, the battery is not charged from an alternator, when running, but rather from the Transfer Switch 120VAC through fuse F3 in the TS -- a trickle charge.

[@glennarchdekin1279]

Would you have a picture of this fuse in the transfer switch. I have a 22kw.

[@mkowitz]

@@glennarchdekin1279 I do, but don't know how to attach it. Inside the (newer) Transfer Switches is the SACM (Smart Air Conditioner Module) that has three fuses, the rightmost one is labeled T1 (not F3, sorry). This is the one that feeds 120VAC to the battery charger in the controller in the generator. The SACM is black, plastic, with all of the control wires from the generator going to it, along with a Molex plug on the right-side, connecting various limit switches and sensor wires on the TS. Hope this helps you out.

[@repure1999]

What if you don't have power and rely solely on gas to power the generator for power?

[@mkowitz]

@@repure1999 Then the generator output powers the battery charger.

[@BrianD-ds4dx]

In the generac, the battery charger is powered through the low voltage that is run to the controller, as the charger is integral to the controller. The Kohler controller is similar, with single low voltage. Cheaper to install (slightly) than similar sized Cummins or Briggs because fewer low voltage. However….if your charger goes bad in generac or Kohler….get ready to pay 800 to 1000 to replace the entire controller

[@timshea5158]

Always disconnect negative lead first then positive. Reconnecting leads connect positive first then negative. If the negative is connected and your wrench slips on the positive, you will get sparks!

[@conniehopkins6105]

I sure wish I had seen your video before I had the installer come service my Generac when it stopped working. He changed the battery and charged me $450.

[@tonyjordan1320]

Owww ,that borders on price gouging...

[@kendodd1]

Thanks for your video, it was extremely helpful

[@NewtonWashinton]

Optima Red Top AGM is what I have used for 10 years now trouble free. BTW the system uses a trickle charger to keep the battery charged. I have mine set to run every other week for system check, I change oil every yearPennzoil Ultra Platinum 5W-30 Full Synthetic.

Battery replaced but orange alert light still lit up ( “check battery” in the input pad readout screen but scrolling through the menus to the “battery” option seems to go nowhere, just an endless loop of repetitive options) and the recommended remedy to turn it off hasn’t worked :-( Tech scheduled to return in Oct for semi annual maintenance so will live with it till then and maybe he has the magic formula :-)

[@DIYSEMI]

Mine does that as a yearly reminder to check the battery...but i can just clear the code in the service menu...wonder why yours wont clear.

[@royaltee7950]

Very helpful...thank you!

[@Acts238Church]

Generators are a good idea.

[@dougthornton6884]

#1 Unplug the molex connector under controller before touching battery. This disconnects the charger. You blow the charger, you replace the controller. #2 Always remove the negative battery cable from battery first. Then you can't short the positive to the enclosure, as it is no longer connected to the battery. When installing new battery, reverse procedure. #3 Opening the 2 pole breaker does nothing. It is only there to comply with codes and limit load on the generator output. Turn generator off from the controller and pull the fuse. I service many of these units yearly. Some models require dealer code to reset maintenance log. Look for a keypad hack on the web to get around knowing the dealer code.

[@Boeing767DriverAA]

This a video on how not to do it. I was waiting for an arc from the battery when he got real close to touching his wrench to the casing..... Scary!

[@brozbro]

Good video. The Geniuses at Generac designed battery placement making it almost impossible to access.

[@kmatlaker]

the 11Kw shown above looks a lot easier than my 22kw. I agree

[@moboutmen]

I take the whole side panel off my 22 to replace the battery.

[@craigvelardi7420]

So I just purchased a house with an 8kw Generac and it was tested and running 3 months ago. Today I checked it and the RPM Sensor Loss light was on. I am assuming it pertains to the battery. First, when you tested the Generac, shouldn't the house main panel switch be off? and 2) can the battery be trickle charged and put back in or is it not worth it ant get a new one? Is there any other things that may cause the RPM Sensor Loss light to come on?

[@kelleyskitchen9046]

Great information. Thanks

[@richardbarkley9909]

I see you removed a Duracell battery that you said was 7 years old. I installed a Duracell from Sam's club in ours brand new in June of 2020, its nearly October of 2023 and its showing just 12.1 volts. thats barely 40 months. We're in Florida where its hot and humid......

My screen was right where you were but it flashes back and forth to show hours only and right back to screen you show. Is it supposed to go back and forth like that?

From a retired tradesman, you didn't put the month and year of installation on the battery. That's the first question will ask on a failure, "how old is this thing?"

[@MrAlanGilmour]

Error code 1902 is not low battery voltage, but an issue with low generator output voltage issue. Having said that, I would replace the battery every 5-years. The actual error code from the diagnostic manual is: "Both Zero Crosses Missing. Under voltage due to faulty excitation winding, or zero cross circuit, or circuit in general. Probable cause: loose wiring, field boost hardware failure."

[@timedwards752]

Easiest way to tell is to check the voltage on the battery. If it is between 13.4 and 14, battery is good. If it is 14 or higher, change it. This is because as the battery ages, it builds up resistance inside and takes more voltage to keep it charged.

Honestly, it doesn’t feel like on my generator I can get the battery out without removing the end portion with the vents on it. Everybody watch it looks like people can just slide these batteries off but mine seems like it has no room.

Get rid of it, if you ever really need it for any prolonged use it will probably break. I have a 22kw on my house it is about 6 months old and has no hours except for the weekly exercises. Well hurricane IDA hit and we ran it for 2-1/2 days and the gen-set has burned up we lost all the food in our refrigerators and are sleeping in 100-degree heat for the last 4 days. Last night I yanked that POS out and replaced it with a 20kw Trane unit and it runs like a Trane. I own an industrial supply house in New Orleans and we are a Generac distributor my brother-in-law purchased the same 22k unit from me and it has never been run. We installed it and it doesn't generate electricity. If you like a boat anchor in your yard to change the oil, air filter, and battery because you are bored buy a Generac, if you are looking for a generator that works, purchase a Kohler, Trane, or Onan and I have PLENTY of people who have this same problem but I don't want to make this comment any longer than it already is.
