Asiera, I see what you mean now by "actuator". You are referring to your trim tabs. This does not make sense at all, why you should be getting power to your tabs when the bilge switch comes on. Even fully retracted, my Lenco trim tab indicators light up with the top 1 LED. I get this 1-light indication when I first turn on the key and the tabs are powered up, causing them to fully retract. Do your tab indicators light up also when first turning on your key, or do you have to power them with a dedicated switch?
As far as the bilge and washdown indicator lights coming on at the same time, this does not seem typical either. I have heard of cases where a single pump may be shared for both baitwell and washdown purposes, but not in my 2120. These are usually 2 different styles of pumps.
I'm thinking somehow your switches are wired other than the typical configuration. What could mislead someone installing a switch panel, is that there is an extra tab/connection that gets "negative/ground". This is only for the purpose of having the opposite polarity available for the switch's light indicator. Otherwise, the switch only passes "positive" polarity through it to power devices.
Is this original Parker wiring from the factory, or re-wired years later? What year boat? Thanks for the pics. Every bit of info helps.
At first glance, I'm thinking somehow some of your loads are not getting continuous (unswitched) grounds, such as all loads connecting their negative wires to a ground bus-bar. Just like house wiring, all outlets and lights have their neutrals (white wire) uninterrupted and all connected to one bus bar at the panel. Only hot wires are interrupted through switches, breakers, dimmers and fuses.
