Can You ground a dome light with a dash switch?
Can You ground a dome light with a dash switch?
Ground the dome light with a local switch, a dash switch, any door pin switch, an open collector electronic switch instead of a bunch of hot wires hidden in the overhead. That same HOT wire could be used to power those cute little aircraft style reading lights and a DOME light.
What to do when dome light goes off?
‘Shut the doors and see if after the lights go off, if there’s still 12V showing on that fuse. Pop the little lens cover and measure voltage at the dome light bulb. From one contact to ground then the other. The old way was to power the light and switch the ground. The door pin switches would just ground a wire.
Where is the Contant wire on a dome light?
dome lights tend to be controlled by a car module which usually turns the lights off after a period time, the best solution is not always the easiest one. Also the dome light’s contant power wire wouldn’t be in the roof where the light is, it would be at the switch that activates the light.
Where does the 12 volts come from on a dome light?
The 12 volt came from a body feed fuse that was likely live all the time. See if the 12 volts is switched or the ground is switched. If you can turn the dome light on from a switch at the dome light it probably has 12 volts there.
