Hey all - have a Guardian (044563) circa 2009 and it’s been super reliable over the years. Had an oil leak fixed several years ago but other than that just regular battery replacements.

Anyway, went out to manually run it, and where it would normally start, it just made a loud pop/bang. Loud enough that my wife heard it inside the house. I mean it was like a gun shot. It could’ve been a backfire I suppose (runs on propane), but I’ve never stood that close to a backfire to make a good comparison.

After that I waited a few minutes, inspected what I could, fuses, etc. and tried again. This time no bang, but just a low irregular buzzing sound from beneath the panel where the circuit breaker is located (on the right side of the generator when opened).

I have no issue calling someone in to check it out but wanted to see if anyone here goes “oh it’s this for sure” or not before I do that.

Thx!

EDIT… SOLVED: Side of the battery blew out. It wasn’t obvious because it was the backside, and the wetness around the battery was mistaken for rainwater (storm had just come thru).

We are dealing with the aftermath of Hurricane Lala here on Hawai'i Island. In our area only was a tropical storm, But grid-power has been out since noon Saturday. Our Generac 22KW/999 Guard-No T/sw AL has been running perfectly. 3 people live in this house and our 250 gallon propane tank is at 70 plus percent. Generator just over 1 year old. Does anyone have experience with long outages? I think we will be fine for a couple more days but am hoping someone with more experience can share their experience. Power co. thing power will be restored by Tuesday pm.

Has anyone else run into this issue?

Does anyone have manuals for a SD0030-A162.6D18HBYYC diesel industrial generator?

I am quoting an install and the customer wants to elevate the HSB. How to you typically get the generator onto the stand? Most likely it would either be a 2’ or 3’ stand. A crane seems like the most expensive route but probably the best option.

Lifting the genset with 4 people might be possible for a 2’ stand but seems like a bad idea.

Ramps? Another thought was to setup a temporary platform and use ramps if the customer wants a 3’ stand.

I have had a 48kw liquid cooled for several years now and in May of this year the controller died. We had a large lightening hit to the back of my property (lots of iron in the soil here) and STILL it is not working. I live in Central Florida and the dealer that WAS servicing it, took 3 weeks to get to the site to look at it, then a month and a half to even quote it and at that, they no showed on the repair.....TWICE

I called 3 other dealers in the area, all of which sent techs out to confirm it was the controller, and they all ghosted me.

I finally got one newer dealer to install the controller, but they cannot get the firmware loaded and today, the original dealer was supposed to show this morning (third appointment) to also replace the controller (I was just going to keep it as a spare and send them on their way).

This is VERY concerning, not having a running backup generator during hurricane season has given me serious doubts.

I have called Generac corporate who really were not totally helpful and believed that eventually the repair would be made.

Has anyone else seen support fall off for Generac? Is there an alternative out there for this? Is it just Florida?

Thank you!!

I have an older model Generac 0052400 home generator, which is 120/240 AC, 7000watt system. It has been well maintained but with this past storm, it did not switch on when power went out. I checked and battery was dead. I put new battery in but within a couple of days, battery was dead. I checked battery and it is good. Upon researching I noted, one of the common issues is the T1 fuse; however, when I opened up the transfer box there are only 2 fuses. I checked both and they both tested ok at 120V. When I charge the battery, the system runs perfectly but it quickly drains the battery, even when not running. Any ideas? Also, should there be three fuses verses 2 (all videos show 3???)

Appreciate the assistance.

Hello, I’m looking for others who have had issues with the new units. I’m on unit number two since March. The first unit never ran and had catastrophic failures and with help
of legal counsel it was replaced. Now since June when replaced its failed twice and I’m at my wits end. In all I’ve only had a working generator 5 weeks since March, I also even switched dealerships hoping for better service techs. I have no issue with the tech he’s been wonderful but I do believe they’re selling faulty machines. I do have a direct person of contact at Generac who I’ve emailed again about this failure.

Currently…getting the dreaded 1902, prior to that it was a diff alarm

I have been looking at investing 7-12k into a generator. But this new advertisement has me thinking I’ll take my business elsewhere. If you haven’t seen it, be happy.
