SIMRAD radar interface (RI10) - I think it might be faulty.
Everything used to work fine - but now my NSS8 chart plotter will not switch radar on. The NSS8 can see the RI10 - it shows in the device list. It's status on the chart plotter says 'OK'.
I have checked power is going to the RI10 - with multi meter - yellow and red leads in the main cable both have the same volts as house batteries volts. But the power light in the top right corner above the power lead does not show any lights.
The simnet light above the simnet cable is flashing away nicely.
I have checked with a multimeter the volts being sent from the green block to the radar dome. The red is showing same volts as the house batteries. However, the yellow control power is showing about 1.2 volts less than house batteries.
Any thoughts anyone ?
