Electrical Loads from Ignition Switch
Posted: Fri Aug 07, 2020 12:42 am
I was under the dashboard of a boat today solving a electrical wiring problem that was "installed" by my otherwise superb mechanic.
(It's not germane to my question but if you are curious, the fuel gauge would work when you turned on the Perko master power switch, but would drive back to zero when you move the ignition switch to "ON". I solved that one easily enough).
Is it "ship shape" to power the red and green sidelight lamps and the white all-round lamp ( which each have a simple 12-Volt bulb) from the same power source that powers the instrumentation, the ignition switch?
Or should I have the navigation lamps be powered separately from the ignition switch?
Is it okay to power the tank selector solenoid through the ignition switch?
Or is that bad form?
