Lowrance LMS 520C

I have a Lowrance LMS 520C gps and it's giving trouble. It turns on ok but only stays on for maybe 10 seconds and then turns off again. Anyone know anything about these?

Could be several things.

First, do you have adequate power to the unit? I believe it's advertised as 9 to something like 35 volts, but mine used to shut off above 9 volts (as near as I could tell.) Good first step would be to measure the input voltage.

10 seconds, it has likely gone through at least some of its self-checks, and is possibly trying to load the basemap. If you look close, there will be a very thin status "bar" at the bottom that lights from left to right as it goes through all the checks. It finishes not quite all the way to the right, as I recall. If you have a card in the unit, remove it and see if that helps.

If it is failing one of the self checks, there's not much you can do but return it to Lowrance for repair. In the US, they have a flat fee repair price; last time mine had water get in they sent me a new unit.

Luck

Lowrance LMS 520C

Hi jyasaki,

It has been on the boat since new and worked fine for years so I would assume it has an adequate power supply. It was just at the beginning of this season after being stored all winter when I tried to turn it on it started this. The screen below is what I'm getting when I turn it on, it stays on like this for roughly 20 seconds and then turns off. Pushing any of the buttons does nothing.
I checked and there is no card in the slot at the front.

Any help would be appreciated

It looks like it has 12.4v...

Have adequate power at install doesn't mean it does now... Corrosion could affect power. But 12.4v should be OK...?

That looks more like it is waiting for you to confirm that message or something...

I tried pressing every button to get rid of the message but nothing works

First off, 12.4V is plenty. Doesn't look like power is a problem.

That is the "legal disclaimer warning" that is brought about from the overly litigious US society. You have to press "Exit" to clear it, which gives the manufacturer a claim that you read it and agree with it. If the Exit button doesn't work, it's likely that your keypad is toast. Alternatively, you could have a bunch of salt or sand in there that is keeping it from working. Can you switch pages behind the message? I notice there is no basemap showing.

More troubling is the power off thing. You have adequate power, so it shouldn't be that. Have you tried disconnecting the other cables (transducer, GPS antenna) and see if that makes a difference?

Hi had similar problem with my 3500 a few years back. The solution was warm water over the keys as they were salted up. Try phoning their help line.
