Does anyone know how to disable the CO Guard feature on a Briggs generator? We run this thing in a shed that’s outside of the camp. It’s a pain in the arse even with a fan ventilating the little shed.

Extend the exhaust out thru the wall.

so run the frickin exhaust pipe out the wall and then mount the muffler to it, its just regular 1" threaded pipe, it aint that hard.

if you insist on killing someone, then its most likely just a simple one wire safety kill switch circuit to connect to engine ground

We’d rather not go through the wall. And for crying out loud i said it’s in a shed specifically for the generator. No one stays in there, dolt. How the frick did you survive all these years without this sensor on yours?!?!?

My apologies for maybe being a little harsh. But i just finished reading replies on the OT. Should have known better than to post on there.

well then just run it up the wall then go out just under the rafters, that way no worries about any rain water getting in from the hole.

you could also go straight down through the floor with it but if you insist on disabling the thing then its most likely just a simple ground wire kill switch circuit, shouldnt be that hard to disable but you have to provide pictures and maybe describe the wiring.

also i bet there is a youtube video showing you how to do it. they always have videos showing how to defeat safety devices on things

that said, the shed can build up so much CO2 that it can choke out the generator and be so toxic that the person going in there to restart it can pass out inhaling such a concentration of gasses and it could be lethal if no one is there to drag them out to get fresh air

no worries

but understand, you are asking us to tell you how to rig something that will be a present danger to those around it.

its not just the mice and roaches that may die because the shed has zero oxygen and toxic levels of CO2 that can make you pass out when inhaled. think more ways to ventilate the shed then that will make it less dangerous as well as not choke out the generator when oxygen levels drop too low

I run this thing outside away from my house but I keep getting fault from the co guard and it keeps shutting off I just want to take this thing off I'm not going to run this thing in any houses or enclosed spaces but live in California and get random power outages because of wildfires. I'm tired of waking up in the middle of the night in 105 degree temps to get this running again please help

I can tell you how I would disabled my Brigges and Stratton CO device
I certainly understand your issue the CO shutoff module didn't come out till 2018 so there are millions and millions of Generators out there that have never had one. While I understand the intent is for saving lives and their are mini people whom owe their lives to this type of device.
However people who purchase a generator with a specific purpose, location and enclosure to run it in are now adults / professionals subjugated to a nanny controlled device.
OKAY so this is what I would do if I wanted to disable mine. I'm not telling you to do this. This is what I would do hypothetically.
Open the control housing and you will find a small circuit board with a battery shouldered to it. At one end of the circuit board is a four prong connector I would simply unplug it. The four contacts do the following things. 1 connect to neutral
2 connect to Hot 3 connect to ground or chaise 4 closes or opens circuit to ground or chaise when CO is directed.
1 and 2 charge the battery 3 and 4 open close the grounding circuit allowing the motor to start or forcing it to shut off.
