Hi Guys

I have the above old motor. Works well. I have sounders etc on the boat and
my concern is that the motor does not have any regulation from it's charge
circuit. I have seen it fluctuate to 16V at times.

I can filter out the line noise but need some ideas that I can use to get my
instrument panel to 12-13V .

Any ideas please

Many thanks
Alan



As Clams suggests, but equally don't be too concerned; those systems
never really put out much power (volts & amps together) so your
batteries etc are unlikely to be damaged. As soon as you put any sort of
load on it the excess voltage will go away.

You know this brings to mind Krause's endless stories about "buying"
boat electronics online for his 36ft lobster boat:-) & other fantasy
boats:-) Of course anyone can do web searches, even lying non boaters:-)

I have designed a regulator that only loses about 1V so it will hold at 13V
but not sure if there was a better method.
but then if voltage drops to 12V I sit at 11, not too much of a problem.,
guess it's trial and error.

thanks guys

It's not the batteries that are at risk - it's the fishfinder/GPS
electronic thingies.

Naaa clams they're fine at that low power. A notional 12 volts
"designed" to be connected to charging systems is well protected from
that low over voltage. The actual electronics themselves don't run at
anything like 12 volts, mostly a well controlled & stable 5

I had an old merc with the unregulated charging system. It will fry an
automotive battery. You need an old style marine battery to hold that voltage
down or get the new style regulator/rectifier. Light bulbs take a beating at
16v and I actually melted my running light lenses.

Nonsence my good man.... Anyone with a CD player can tell you that
Aerosmith, Sabbath, or Zepplin played **loud enough** can keep that pesky
voltage down just fine.

The Boston Symphony playing Richard Rogers - "Song of the high seas" is more
appropriate for boating. That is particularly true in the Chesapeake when its
blowing out of the south. (as I recall)

Yesterday I was in the local WalMart looking at maybe replacing my
Playstation 2 with an Xbox and wanted to scope out the games. As I
was passing by the music end cap and the Stones "Paint it Black" was
playing. The guy standing there, looked to be about my age, turned to
me and said "Every time I hear that song, I get the chills". I said
"Me Too". He says "I Corps?" - yep and it went on to swap unit and
service time in 'Nam.

When I saw this post, I thought it was a great chance to discuss
"Theme songs of your life".

For instance, when Harrison Ford rescued those stranded climbers a few
years ago in his helicopter, do you think the Indiana Jones Theme was
running through his head?

If I had to pick music for my boating activities, I'd have to pick the
"Victory at Sea" theme from the '50s documentary TV show.

Later,

Tom
