Re: Re: Roof wiring: “Roof up” warning light
Hi,
I installed the “roof up” warning light by putting a 6.3 mm (1/4″) double spade plug on the white wire of my ammeter. This wire goes to one terminal of the light. The other terminal goes up the windscreen center section to the roof switch. I used green/white wire (“ignition switched accessory”) and spliced in a Lucar plug above the windscreen so it looks proper, even though I’ll never remove the roof again. The hardest part is putting the wire up the windscreen divider, which requires either three hands or some glue (I used glue).
The black sash under my windscreen has a large rectangular hole in it for a 5W festoon bulb (the kind used in vehicle trunks [boots]) that replaces the dome light as a map reading lamp. This is now switched by the standard dash switch for the dome light, which is no longer installed. There is also an unused 1/2″ round hole in the sash made by a previous owner. I mounted the “roof open” warning light in this hole instead of in the Martin Walter spot on the instrument panel. It was making me too nervous to drill a big hole in my instrument panel! Someday I can move it, if I want.
Finally, I tapped the purple battery wire on the dome / instrument panel light switch to carry power to my 8W fluorescent roof lights, with another 6.3mm double spade plug. I used the dome light wire that was already in the windscreen divider (purple).
It all works and no fires, yet!
Now I can put in the interior trim panels!
