Recently I had a new carbon monoxide alarm, which is mounted on the bulkhead in the head, go off when sleeping aboard.
Everything seemed fine but I opened all the hatches just to be sure. Later the detector kept going off occasionally.
-No fuel burning devices where running.
-No alcohol fumes from the stove
-the batteries weren't charging to produced hydrogen.
I moved the alarm to the settee area and it was fine for a couple weeks.
A few days ago I put it back in the it's mount on the head bulkhead, and today it started going off again.
I found this list of possible gases that can trigger a carbon monoxide alarm...
Other gases that can set off carbon monoxide detector includes:
Have you heard of fumes from a holding tank, causing a carbon monoxide alarm to go off ?
The smell from the tank isn't really bad, although it is noticable. (to be resolved next spring with a likely switch to an MSD Potti)

I found this list of possible gases that can trigger a carbon monoxide alarm...
Other gases that can set off carbon monoxide detector includes:
- Isopropyl alcohol
- Sulfur dioxide
- Acetylene
- Propane
- Hydrogen sulfide
- Dimethyl sulfide
- Mercaptan
- Ethyl alcohol
- Ethylene
- Methyl alcohol
- Hydrogen cyanide, and
- Nitrogen dioxide
So mercaptan and hydrogen sulfide are on the list..."Instead of oxidizing the waste completely, they go only part way, producing some extremely malodorous products in the process; organic acids, assorted mercaptans, and hydrogen sulfide gas are chief among these"
