Navman 5500 chart plotter help

[jon and michie]

Hi - my navman chartplotter seems to have died.
When I was using it last year it started to switch off after so many minuets - which I suspect it was taking power from the internal battery.
I have checked the main power source there is 13 volts present - so is there an internal fuse which could of blown?
Any opinions welcomed
Jon

The manual mentions a fuse on P.73, but not much more than that.

Time to get the screw driver out.

I’m impressed it’s still working given the age of these units. Mine packed in about 8 years ago, tried sorting the fuse and battery but no luck. Still in a box in the cupboard. Replaced it with SH unit and now a B&G plotter.

Try Service Centre, they have repaired Navman/Northstar and Raymarine stuff for me, I’ve found them honest reliable and reasonably priced. Their system is geared to contact via their ebay shop which I initially doubted but can see how it makes their tracking easier. I use the fixed priced estimate option.
