CO/Propane alarm

[jrmartin67]

I know this has been posted previously and that the most common "culprit" for the alarm going off repeatedly (with no propane or CO problem) was thought to be low 12v system voltage. dumb question here: how does one check said voltage if one's battery is switched off? is there a convenient place to stick a VOM? We camp in a 2011 Flagstaff V-Lite This is driving us nuts!! If I disconnect it, of course, the propane solenoid closes. Good plan, but false alarms are past annoying. And if it IS low 12 voltage what can one do to correct it? Thank you in advance, fellow semi-happy campers!

Many of us ended up replacing the detector. Seems like the advertised 5 year life is too optimistic. I replaced with a propane only alarm and a separate battery operated CO alarm. No problems since.
