I have an Es75 MFD and am receiving interference from the alternator which causes the screen to go black - for from a few seconds to 30 secs or more. Whenever I accelerate the engine from idle it causes the screen to go black. I have installed a voltage stabilizer on the power line which had no effect. I have experimented with a separate power line direct form batteries to MFD not near the alternator with no effect. I tried a shielded power line with no effect. I now suspect the interference is coming through the air and not through the power input line.
Is there something else I can try? I am surprised that others have not encountered this problem which makes me suspect my Es75 may be defective. Can I return it for Raymarine to check/replace it?
