Get rid of the ProMariner! It is state-of-the-art 1980's!

Subject: Re: [C320-list] Electrical problem
After the electrical system seemingly checked out okay yesterday, the
original problem returned on today's sail. With the battery set to "2", she
started right up and I motored about 10 minutes to the gas dock and she
started again without problem after filling up. I then motored out for about
25 minutes and then sailed for about 2 1/2 hours. Near the end of the trip
the radar blinked off and gave a message of "no data source." The chart
plotter stayed on but there was no radar. It's my understanding that the
radar will do this if the feed drops to 11 volts. When I went to start the
engine a short time later, it was completely dead. I switched the batteries
to "All" and it started right up. It seems that something is draining the
batteries. The batteries, though old, checked out okay in a load test
Saturday. FYI, I have the ProMariner 30-3 charger. Any ideas would be much
appreciated.
Thanks,
Mike

I had a Promariner that cooked my 1 year old 4d flooded batteries.

Warren - it is Mike that I am thinking still has the stock ProMariner. If
so, that probably is the culprit for his problems. - Allan

Allan, I don't have a ProMariner. Mine is a 50A LewMar that was on the
boat
when I bought it. According to the manual, it will float the batteries at
14.1V, although I don't leave it on when there is no DC load. The charger
relay for the starting battery kicks in at 13.7V. Apparently, a constant
voltage around 14V will not hurt the batteries. The previous set of
batteries lasted 7 years so I expect my charger works OK. ---Warren

Warren - Does the ProMariner reach and maintain float? I thought that was
the problem with it - it just kept on cooking and is not a true 3-stage
charger. But I could be wrong... Where is Jeff Hare on this?! - Allan

Mike, according to the experts (not me,) the only way to assess the health
of a wet cell deep cycle battery is to perform a load test on it. All
previous advice is useful.
Water the batteries, clean all connections, and recharge. Monitor the
charging voltage to be sure the charger is working correctly. When the
charger enters float stage, disconnect and let the batteries sit for a
day.
After at least 24 hrs. test the voltage again on each battery. If still
high, they're good. If dropped by more than a tenth or two of a volt, you
may have a problem. Have a load test done.
As Karl suggests, you can test each cell with a hygrometer (compensate for
temp.) to determine if one cell is weaker than others. I recall that if
the
cell to cell difference is more than .20, the cell is likely weak.
Four years is on the near side of lifetime for deep cell batteries
constantly charged. Consider that your charger could be the problem.
If the tops of the plates inside the cells have been left high and dry for
any length of time, chances are your battery is done and can't be
recovered.

Mike,
Also check the connections and the cables. Several times I've come across
a
situation where a dodgey cable end or connection would handle the low
current demands of the fridge and GPS but balk at the couple of hundred
amps
required by the starter motor.

Mike,
Check fluid level and add distilled water as required. Charge over night
and
then check each cell with a hydrometer.

Last weekend I went out for a day-sail. I usually put the battery sith on
"both" but I forgot and left it on "2" for the trip. The engine started
normally, I motored for about 30 minutes and then sailed for about 2 1/2
hours. When I went to restart the engine it was dead (no sound when
pushing
the start button). I changed the battery switch to "both" and the the
engine
started right up. The electrical draw during the sail was a fully cooled
refrigerator, the chartplotter and ST60 gauges. My boat is always plugged
in
to shorepower with charger on when in the slip. I have two wet-cell
batteries that I believe are about four years old (I've owned the boat for
2
1/2 years). I'm not knowledable about electrical systems so I'm looking
for
advice as to steps to take to find possible problems when I head down
there
this weekend.
Thanks to all,
Mike P
