Thanks! I'll check them out.

I know what you mean about the distractions of new equipment. I'm a
professional pilot and have seen that before...more time than once.

I guess I got a little hot under the collar at the guy that originally
responded to my post. I asked a very simple question that has a very simple
answer. If he didn't know it, he didn't need to respond. He didn't need to
come here and start talking down to me as if I was some child that he need
to teach a lesson by starting his reply by saying something about "first a
reality check and a physics lesson". I think I have those covered. I just
asked if anyone knew of a specific procedure to fix a known problem with
this GPS.

I know that it would be easier to replace the GPS than it would to try to
fix it, but it's just a backup. I have a nice new Garmin unit on the boat
that I use 99% of the time. I just have this Micrologic unit up in the
tower and would like to use it as a backup or to mark a spot where a fish
was caught so that I could return to this spot if I happened to be in the
tower when we hooked up. Also, I live 4 hours away from my boat and only
get there every third weekend at best. I don't want to spend a lot of time
re-wiring the boat for a different model GPS. I'd just like to bring the
one that I have home so that I can fix it there, then when I'm back at the
boat, I can plug it back in and be off and running. It's perfectly suitable
for what I use it for. Since the company is no longer in business and I
can't have it repaired there though, I was just hoping that someone knew
what the connection was that needed to be un-soldered to keep the battery
from dying prematurely.

Thanks again to all who responded!

I recently purchased a used Micrologic ml250 GPS to use as a backup GPS

my boat. After receiving it, I realized that the internal lithium
battery
was dead. I wanted to have it replaced, but Micrologic is out of
business.
I've done some reading online and discovered that it's not terribly
difficult to replace them yourself, and that there is a fix out to
prevent
the battery from prematurely draining in about a year as compared to 7
years
that Micrologic advertised.

I understand that the fix is pretty simple as well. You just need to
un-solder a connection to one of the chips. Does anyone have the
details of
this operation? Which connection needs to be un-soldered?


Thanks!

There is a place called Goertz where I sent my Micrologic Mariner when its
battery went out. They
had it back quickly and it is up and running. I was able to find this:
Frederick Goertz, Ltd
Victoria, BC V8T5A5 Ph: 250-386-8375 .

And this: http://www.frederickgoertz.com/about.php

On a personal note: Don't let people beat you up about your old
equipment. A bit of thought (an
endangered commodity of late) would most often reach the conclusion that
an older piece of equipment
or software with which the owner is experienced (so that its operation
becomes second nature) is
liable to be more valuable when weather or seas get messy.

I'd rather sail with such an owner than one who is distracted by every
shiny piece of equipment that
comes down the pike but never quite gets a complete handle on operation,
or spends so much time
looking at the gear that the Texas tower in the vessel's path - somehow -
escapes notice.


I have done a lot of electronics work but am not equipped, mentally or instrument-wise, to do this
kind of work in my Micrologic. Goertz did a good job and I don't think they charged all that much.
But, as they say, Your mileage may vary.

Fair winds,
