Re: Stus-List Nova Kool Recharge

No house calls.  You have to disassemble and ship to them.  The fittings
are hermetic and lossless so you just wrench them apart and ship.  They fix
and recharge and ship it back.

Dave, go the conductance route.  It is a quick and easy way to test you 
batteries, is as accurate as other methods and will not actively damage your 
batteries, which is possible with the antiquated load test method.

Re: Stus-List Battery tester

[Franklin Schenk via CnC-List]

I like the KISS method.  Use a multimeter to check the battery when fully 
charged.  It should be about 12.5 volts.  Check it when the engine is running 
and it should be 13.5 volts or higher.  If the battery cannot be recharged to 
12.5 volts, it is probably bad.  That is when you pull it out and take it to a 
battery store.  This has worked for me for more years than most of you guys 
have been alive,.

Re: Stus-List Battery tester

[Josh Muckley via CnC-List]

The best indicator of health IMO is the Amp-Hour capacity compared to the
manufacturers rating and historical measurement.  Typically you would
measure them at a C/20 rate from 100% 50%  so a 100AH battery would test at
5 amps for 10 hours.

The problem with typical resistance loads is that as the voltage drops so
does the current.  The load has to be regulated.  It would also be nice if
the load didn't over discharge your battery.

I have a Computer Battery Analyzer (CBA) from West Mountain Radio that will
perform this test nicely.  Check them out.

My NovaKool LT200 refrigerator has been under performing and after 
running through a list of possible issues I am convinced that it 
needs a refrigerant recharge.  I have checked into it and it doesn't 
look difficult.  But I am a little concerned about either under 
charging or over charging the system.


Can this be done without purging the system with a vacuum and will 
the gauge on the hose be sufficient to get the right amount of 
refrigerant into the system?

Re: Stus-List Chart plotter problem

[Jerome Tauber via CnC-List]

If it's rf noise generated by the alternator it may be coming in through your 
GPS antenna as well as data or power lines.  If it is rf noise you should be 
able to hear it with a small AM radio held nearby (tune to around 1400 KHz).   
I still think your voltage regulator is suspect. When the battery reaches its 
maximum charge of approximately 14.2 volts, the regulator will then limit the 
alternator's output. The battery acts as a buffer so that may be what's causing 
the problem to sometimes not show with the engine on..   If the engine has been 
off for a while the battery voltage may fall in the 12's and it may take a 
while for it to overcharge into the 14's where your chart plotter may start to 
act erratically again.   When you turn off the engine it may take a few minutes 
for the voltage to drop back into a safe level.   You said you are measuring in 
the 14 volt range with the engine on.  If it is above 14.2 that would be 
suspect. Jerry  J7J

Given the intermittent nature of the problem, this would be challenging to do 
long enough to be definitive.  I am also not sure it will identify the source 
of the problem since it appears to be the power (see below).


2.   Put a scope on the DC bus to see what, if any, AC/noise is on the 
line. Include an engine start with this.
I don’t have a scope and have not used one.  What kind of device would you do 
this with?


3.   Disconnect the NMEA interconnection and see what happens.
As I said, when this happened last week, the NMEA input was disconnected from 
the chart plotter, so this seems to be coming from the power connection.  What 
is frustrating is that yesterday, I started the engine twice, once before and 
once after the race, and the chart plotter behaved perfectly and never beeped 
once.  Nothing was obviously different??

 

 

 


4.   Check the NMEA connection for configuration. Does the plotter send and 
receive data or just send? No need to have the NMEA input line connected if 
there is no data headed that way. 
5.   Put a laptop on the NMEA connection or run the diagnostic window on 
the plotter, if it has one, and read the raw NMEA stream to see if it is 
getting some odd data or any data at all if it should not be.
6.   Put ferrites on all incoming wiring.
7.   Check for ground loops and NMEA isolation*
*
This one is a bit tricky. First off, make sure the power supply and ground 
connections are at exactly the same place as your other electronics. Ground 
loops are bit complicated to explain and hard to find, but the short version is 
this step will eliminate some of them. Second is check with the manufacturer to 
see if your plotter NMEA connections are true marine standard opto-isolated. It 
is very possible to use direct wiring to NMEA data and not isolate it, my 
laptop/plotter does just that, but optical isolation prevents various stray 
voltage and ground issues from messing up the data.  Equipment is fairly 
resilient now, but back in the day an engine start could generate noise that 
would totally screw up electronics. Even now I will start an airplane with all 
radios and nav equipment off and then turn it on. I once was delivering an 
airplane that had a screwy alternator I had to switch off to use the radios and 
nav gear and then switch back on when the battery got low.
BTW – my boat is wired so the engine start battery is usually separate at 
engine start and has no effect at all on the electronics. They don’t combine 
until charging voltage is present for a few minutes. Is yours like that?

is very possible to use direct wiring to NMEA data and not isolate it, my 
laptop/plotter does just that, but optical isolation prevents various stray 
voltage and ground issues from messing up the data.  Equipment is fairly 
resilient now, but back in the day an engine start could generate noise that 
would totally screw up electronics. Even now I will start an airplane with all 
radios and nav equipment off and then turn it on. I once was delivering an 
airplane that had a screwy alternator I had to switch off to use the radios and 
nav gear and then switch back on when the battery got low.
BTW – my boat is wired so the engine start battery is usually separate at 
engine start and has no effect at all on the electronics. They don’t combine 
until charging voltage is present for a few minutes. Is yours like that?

Stus-List Third Wave grounding

[mike amirault via CnC-List]

I don’t think anybody was hurt. Jamie said the owner was by himself and just 
not paying attention when he grounded.
There is severe keel damage visible on the outside, but the real damage is 
inside; her “ribs” are broken.  Jamie at SWM said she is likely a total loss. 
Might be a good opportunity to get some nice gear if they part her out. Yes, 
she is on the hard at SWM, left side as you go in.___

Oh yeah something happened to it alright. The new owner grounded hard off 
Little Indian, she is all smashed up inside and likely a write-off.

Given the intermittent nature of the problem, this would be challenging to do 
long enough to be definitive.  I am also not sure it will identify the source 
of the problem since it appears to be the power (see below).

I don’t have a scope and have not used one.  What kind of device would you do 
this with?

As I said, when this happened last week, the NMEA input was disconnected from 
the chart plotter, so this seems to be coming from the power connection.  What 
is frustrating is that yesterday, I started the engine twice, once before and 
once after the race, and the chart plotter behaved perfectly and never beeped 
once.  Nothing was obviously different??

Re: Stus-List Chart plotter problem

[Della Barba, Joe via CnC-List]

Some things to try:

1.   Run the plotter off its own battery. Little 6 ah AGM batteries are 
cheap enough if you don’t have a spare battery sitting around.

2.   Put a scope on the DC bus to see what, if any, AC/noise is on the 
line. Include an engine start with this.

3.   Disconnect the NMEA interconnection and see what happens.

4.   Check the NMEA connection for configuration. Does the plotter send and 
receive data or just send? No need to have the NMEA input line connected if 
there is no data headed that way.

5.   Put a laptop on the NMEA connection or run the diagnostic window on 
the plotter, if it has one, and read the raw NMEA stream to see if it is 
getting some odd data or any data at all if it should not be.

6.   Put ferrites on all incoming wiring.

7.   Check for ground loops and NMEA isolation*
*

This one is a bit tricky. First off, make sure the power supply and ground 
connections are at exactly the same place as your other electronics. Ground 
loops are bit complicated to explain and hard to find, but the short version is 
this step will eliminate some of them. Second is check with the manufacturer to 
see if your plotter NMEA connections are true marine standard opto-isolated. It 
is very possible to use direct wiring to NMEA data and not isolate it, my 
laptop/plotter does just that, but optical isolation prevents various stray 
voltage and ground issues from messing up the data.  Equipment is fairly 
resilient now, but back in the day an engine start could generate noise that

Subject: Re: Stus-List Chart plotter problem

Let me clarify a few things that might help diagnose the problem.  Previously, 
I tested the voltage at the chart plotter.  I have a solar panel that feeds the 
batteries when off the boat.  At the beginning of all these tests, the 
batteries are fully charged from the panel.  So with the batteries charged 
(12.7 v), measuring at the chart plotter power cable, I got 12.2 volts with 
battery 1 only, 12.3 volts battery 2 only and 12.3 with both on.  When I 
started the engine, I got 13.1 volts.  Note that the was chart plotter 
unplugged so I did not confirm that it would have started acting up when 
plugged in (the behavior is inconsistent).
 I am guessing that the voltage drop is expected and 12 volts is well within 
the spec of the B
I am presuming this eliminates the under-voltage possibility.
I previously have tested the voltage at the batteries from the alternator but 
did not write it down because it seemed OK (about 14 volts).
I also did the AC voltage test by measuring AC at the battery terminals with 
the engine running and that was less than the 50mv that was supposed to 
indicate bad diodes.

Is it still possible it is a voltage regulator problem and how would I test?

To Gary’s message:I still think you have a noise/grounding problem.  If 
noise gets into one of the inputs, say the NMEA, there is usually a buffer to 
handle excessive inputs.  If that buffer gets overloaded, the chart plotter 
might act goofy until the buffer gets emptied.  I would make sure you have a 
single point grounding system that all goes back to one ground point.  Make 
sure all connections are tight.

The NMEA was unplugged when it went crazy, so it is not getting in that way.  I 
guess it is still possible to have noise from the DC input?

Thanks- Dave

Re: Stus-List JABSCO DIAGHRAM PUMP

[Hoyt, Mike via CnC-List]

Alex

We have a diaphragm bilge pump in Persistence.  The pump itself is not in the 
bilge and has a separate pickup.  Because of this the pickup at the end of a 
hose can be mounted much lower than something like a Rule pump with the pickup 
built into the body of the pump.  It pumps the bilge almost completely dry.  

The downside is that the GPH rating is much lower than something like a Rule 
pump and the $$$ are more

Re: Stus-List JABSCO DIAGHRAM PUMP

[Wally Bryant via CnC-List]

Well, they don't clog up as much with hair and crud.  But sharp little 
bits of crud will damage the diaphragm.  And eventually you'll need to 
replace the diaphragm.


People who don't replace diaphragms every now and then are called 
mothers.  


How old is the pump?

I have a Jabsco diaphragm  pump which no longer pumps water from the bilge.  I 
partially disassembled it to see if something obvious was going on, but saw 
nothing.

Any suggestions?  If replace, then with what model?
