Thanks to you and all other replies. The breaker panel was in plain sight-what confounded me was the GFI which I finally found. Problem solved
Now, the battery charger
issue can be checked. It appears that the batteries, in fact, may be fully charged, hence the gauge reads "0" -- the green light is on, indicating that a "trickle charge" is topping off the batteries. I'll test the battery
levels--also can run some of the interior
lights for awhile and see if the gauge needle moves off "0" Thanks again.
