Thanks for the reply Mr. Bickford.
On my boat there is no LED lights
on the breakers, they are the old fashoined dark kind.
I did however find the problem:
The stereo was warm to the touch, but the power button was off and the backlighted LCD was dark...In other words the radio
and the tapeplayer was OFF.
Not so, when I disconnected it from the fuse, the 0.8 amp drop went away and it showed a true 0.0 on amps flowing in or out with the rotary switch to any position.
(Disconnected the solar panels
before I did this of course)
So, there was an internal problem in the stereo, an old Horizon MST 60.
Noticed a tape was left in the machine and perhaps the tape motor
was spinning, and have been doing it for severeral months.
Hmm, glad I installed that Battery Monitor
as I would not have found the propblem otherwise.
Not a bad idea "feeling up" the equipment
from time to time, if something is warm, that should be dead and cold, we have a problem, and we did.
But now Mr. Rick and the rest of us can sleep good....
PS...Any recommedation on a good and inexpensive CD stereo player with AM and FM radio
...? It don't have to be no "Marine" stuff as it will live in a cabinet down below and there ain't no deck leaks
down there...Knock on wood...
