co 2 monitor alarms

[georgeconnell]

Hello,

Sitting here on my 466 and all the monitors started beeping. I believe the signal is for low power. How does one ascertain if power fell?

Thanks

Most of these run off the 12v system. Check the volt meters on your bridge. Is the battery charger on?

Or you had CO present?

But I do believe more than just CO will set off a CO detector. In fact, I know it.

In our first Carver, a 2807 Riviera aft cabin, the batteries are in the aft cabin, under the stairs.
I sensed an odd smell in the cabin, but could not figure out what it was. The CO meter started buzzing. I opened the vents and blew a fan down there into the cabin.
Turns out the battery charger went bonkers and was overcharging the batteries, causing them to gas off. Whatever the gas is that comes out of a boiling battery also sets off the CO meter!
