I got down to the boat yesterday and found someone had shut off
the AC circuit on the dock... no big deal, I don't like it, but it
happens, so I switched it on. Later, when I returned that night, I was
reading, and noticed that the cabin lights seemed to be getting more
and more dim. That was strange... and then I noticed that the familiar
hum (it was an old unit was no longer there. Started checking... AC
was fine. The DC panel appeared to be dead... no VHF, no manual bilge
override, no panel lights, nada.

The volt meter showed less than 5v from the batteries (2, start and
deep cycle). Not much I could do at night, so I turned off all DC
stuff, and figured I'd sort it out in the morning.

Woke up and discovered that I seem to at least have minimal DC
volts... no where near what it used to be on the volt meter, maybe 9v
with stuff working. Still no familiar hum. The longer I had a cabin
light on, the more dim it got.

I'm wondering if someone popped it by cycling the AC dock switch on
and off... I'd imagine there would be some sort of surge. I know they
were doing maintenance on the dock... AC power cords were sitting
around not connected to anything, and it wasn't like that when I was
there last.

I once killed a new xantrex charger by plugging into an unlabeled 220
Volt socket. (It was a home brew setup for a hoist that looked just
like 110V dock power!)

The support guy told me there was an undocumented tiny fuse on an
internal board, and sure enough, it had popped.

Yeah, don't doubt it, but this was connected to a real 110v.

Have we put our AC voltmeter across the terminals of the charger's AC
input?

The charger's breaker could have corroded contacts or have just failed.

If it's got AC, unplug the boat from the dock and open up the charger so
you can see its hidden little fuse that probably blew.

If the charger had shorted out, you wouldn't have had any problems
smelling it when you opened that hatch...

Your batteries are toast, being left in this deep discharged condition
long enough for you to read this. You should have rushed to Walmart and
bought an automatic battery charger to recharge them LONG before now.

The charger, when I finally was able to remove it so I could get to
the terminals was toast. It smelled big time, and even after having
been off for a day, was still fairly warm. Glad it didn't cause a
fire. Well, it was turns out, put on the boat in 1991. I guess it's
time came. The DC Amp meter on it was brown. :-}

And, the batts are toast also... they were also pretty old, so it's
not a big deal.

I got a new charger ... Protechi 1220i. I'll be picking up new batts
in the next couple of days.

It's only money... :-}

Isn't that the reason we buy boats?.....getting rid of money before it
spoils??
