Unfortunately I opened both distribution panels and was not able to find an inline fuse in there. So back to trying to find a fuse for the CO monitors that possibly may have tripped. There are two monitors on the boat. One in the galley up high above cabinet and one in the forward birth mounted on the wall. The one in the galley is energized and the one in the birth has no power. The unit is of current design and new. If it is the fuse, would there be a separate one for each detector or are they tied together? I have portable CO monitors on board but really want to fix the stationary one to bring it into spec with the USCG. Any information is appreciated.
