Garmin Chartplotter

[walruz]

Hi all.

I'm just looking for some advice. I have a Garmin charplotter 178 which is hard wired to the battery as a buffer. I have been running it for over 2 years with no probs in this set up. (Plotter is removed when the boat is not being used(.

Yesterday it cut out 3 times with an over voltage warning. I wasn't running especially hard being only 2 up with about 40 - 50 Lts of fuel onboard. At the times it did cut out I was giving some sharp bursts of throttle but no more than many other times.

Any advice or experiences are greatfully received.

Many thanks

Ian

Depends on the type of charging system on your outboard, could be a faulty regulator? Stick a voltmeter on the battery and go for a howl, I don't think it should go over 14V. I'm not a spark so don't take anything I say as gospel

I think it might? Is up to 14.5V not considered "acceptable"?

Garmin specs have it capable of handling 10-35 volts. If you are getting 36volts then you have a problem

Check your regulator/rectifier unit on the outboard and the main battery connections for intermittent bad contact.

Thanks all.

I will do as suggested.
