Raymarine Radar Not Responding

brandonmayberry

I have a raymarine radar with rl70c display on my 2002 FV 342. It used to work fine, then began to be finicky and would at times say not responding. Now it only works with the engines turned off. As soon as i fire the Port engine it makes the radar screen say "Scanner not Responding". Starboard engine has no affect. Even when running at higher RPMS putting out a decent alternator charge it still says not responding. Im not sure where to start. I plan to being by checking all connections but hoped someone would maybe have a hidden trick up their sleeve to fix it.

Thanks!

When Mine says that, I have to turn the power off and back on so I installed a switch just for the radar power.

Thats what i had been finding to be the common answer. I have my Acc. switch by the ignition there that is empty. I may use that.

I have other things that come on with the engine ignition switch. So I fire up both motors first, then all the electronic stuff.

Have not had this but I always fire the engines, then flip on the ACC switch that powers the Raymarine C70 radar, then power the unit.

i used to fire engines and then radar but it stopped responding. I only figured it out by playing around while anchored. Currently i do not have an ACC switch or anything else to power the radar or scanner as its all controlled from the button on the RL70C
