The first problem I found was a bent pin on a connector
to a ribbon cable. Actually it was an easy fix. Another
time it was a fuse located on a PCB--same amount of
work, pulling the charger off the bulkhead--not easy as it
is a 140 Amp charger and quite heavy, taking it apart
and swapping out the fuse.

I suspect the latest problem is a wire with two R-11
connector that link the charger to the controller. At
least I hope so as I'm not totally sure the charger will
shut off on it's own without the controller--need to call
the manufacturer and ask about that. Hopefully, I won't
need a new monitor.

I have not had an PCB problems with this unit. It is
probably coated. Have you seen the spray coating
you can put on PCB's. It works rather well. I tried in
on a DC distribution bus which has a rather complicated
diode array and low voltage sensor, and it has been
working great for several years now.

A good charge controller is an important part of
keeling your batteries alive. I have not had much
luck in that area. My charger died, then I fixed it,
then it died, then it came back to life, then the controller
died. It has been frustrating to me. I'm thinking about
getting a second charger, just to keep the batteries
topped off if the first one dies again.


Do you know what's killing the chargers?
Pull one apart and chech the circuit board..my bet is salt corrosion.

Worth pulling any new one apart and spraying the CB with a protectant
sealer available from any good electronics part supplier...you may
need a cleaner first.

I've done Pcs and Laptops and plenty of equipment not strictly
designed for a marine environment this way and the last without
problem.
Heck, even some 'marine' radios do NOT have sealer on components but
rely solely on waterproof casings....that unfortunately breathe.
