Its probably a failure of the antenna.

It's prob the antenna that's failed, is it sea talk or a nmea antenna?

 

[john m]

Not sure exactly but I think it is name a there's a plug on the back that said that

Sounds like the GPS aerial feed - if its a Raymarine it has an internal battery that can, if your very careful be replaced. Otherwise its £250 ish for a raymarine replacement ! you can buy other GPS aerials that are much cheaper.

How do you open the areal to check

I have a Raymarine(Raytheon) 425 and an RL70. The original aerial was the 120. I have replaced the internal battery in the 425 and changed the aerial to an Evermore from ebay. The supplier was from South Wales and was incredibly helpful. The internal battery was easy to replace except removing the old one. You can buy battery holders and simply solder it to the original connections. The aerial was so simple to change with the instructions supplied with the aerial. I did try to change the battery in the aerial but with no success. One battery is visible but I think there may be something else which we could not access without ruining the case.

I have now removed the areal from the boat I have removed the 3.5volt battery from the areal and checked it is still showing 3.5 volts what should I try now is it worth putting this back together or should I just replace , what is the chances of it being the internal battery in the main unit is it worth spending money on this unit or should I just replace it
