I have a bit of a puzzle, at least for me.
Our instrument displays where changed during winter storage
, (as our old ST70+ faded during usage). No cabling changed. Switching the instruments on via the fuse panel below,works fine, but when turning them of via the fuse panel ( dedicated switch ) they remain on!?
Have tried to connect them to a different switch, but with same result. If I turm the main batteri off/on, then they remain off (if the panel swiitch is off). They can also be turned off via the key pad control at the helm
In rhe past the instruments could be turned off via the panel switch.
( turning on/off autopilot
via its dedicated panel switch works fine).
Best regards - Colin
