Default Garmin 3210 shuts off

New member / sorry if this has been answered before and I missed it. My 3210 shuts off from time to time for no reason. It turns back on with no problem and has been rewired directly to the battery as suggested by Garmin. Dont want to send it in because I dont think they will be able to duplicate the problem. Thanks for any help.

I had the same problem, and it was cured by tightening all connections, and more specifically the fuse holder which was a little loose.

I have the same problem with mine. Called Garmin last week. they said run a wire directly to the battery. I had this problem with other Garmin units as well. I'll try replacing the fuse holder next........

Personally, I don't like wiring direct to the battery. I find the small ring terminals used with electronics wiring get mangled
when mixed with the heavy battery cable lugs. Better to take power off the switch to a fuse block, and from
there, you can run a dedicated electonics circuit (both positive and negative) forward. I prefer to connect to the
battery switch output because a) the connection is switched, and b) it's not something that you mess with very often, so the smaller ring connectors do not get damaged. Also, the switch is usually not over top of the batteries, so corrosion from gasing isn't as much of an issue.

I always use 10 gauge going forward, but I don't do this so often that it makes much difference cost wise. That is, I only do this for my own boats and I don't buy boats all that often.

So, put a small distribution block near the batteries, run forward, put in another in the helm, remove all the stupid little fuses that corrode and you can never find them anyhow, use nice wire, nice connectors and crimp well.

Blue Sea makes a neat negative battery post that gives you a large post for the battery lugs and a bunch of small #10 screws (I think you can buy posts with different screw sizes). Gives you a nice way to connect up the negative side, which is of course just as important as the positive.

Of course, if the GPS operating system is crashing, none of this will help!

Posted this pic earlier but maybe it will help. Did a test run on the bridge yesterday and all is working well. Last thing needed is the GMR18 radar. So far the weak link in the wiring is the tiny guage wire from the gps17 antenna-so small its hard to make a good terminal connection.

Thanks Sea Six - radar's coming its the Garmin GMR18 is on back order-hope to get it in a couple weeks. It will get its own power feed w/ separate switch and a netweork cable to talk to the chartplotter. I had fun laying it all out but I'm glad I did'nt have to pay myself by the hour!

Nice, clean install there mymojo.

I had the same problem on my 178. I secured the fuse holder better than who ever installed it and haven't had any issues since. The fuse holders on many marine electronics are very cheap and will loose connection it they move around too much. Personally, I would wire directly to the fuse block/bus bar without a fuse before I wired directly to the battery.

Checking and tightening all connections is the first thing to try. Make sure the wiring is secured with zip ties to keep it from moving/vibrating around. This should solve many of these problems.

Customer support from Garmin is outstanding, they may just replace the unit even if they can duplicate it. Worst case is you find out it's working correctly and narrow down the list of possible culprits.

inline fuse holders are the divils work- cut em off and use a proper mounted fuse.

I had the same problem, but in a Lowrance. I have done everything suggested, but haven't been out to see if the problem is still there. My fingers are crossed.

prodigalson,
What type of fuse holders do you recommend?

The BlueSea brand unit pictured in mymojo's post is the one I use, or their blade type unit.
