I was a patient man with my gas detectors but not anymore.

I've been down this road, 2 AM. We checked every joint with soapy water. I found the problem to be low voltage. My converter died, buried and gone, will have a wake next trip out.

I ended up adding volt meters just inside the door where I can check voltages at a glance. I also added a on/off switches to the volt meters and the detector which is just underneath them. If I get that wake up call again, I can verify if it's a voltage problem and just shut the thing off if there's no danger present.
