Quick electrical question — the glass 20 AMP fuse for the turning signals on my Silver Shadow II very frequently blows.
I recently had a service performed on the car including a repair of the bright headlight indicator lamp on the dash (the blue light that appears on the dash when the bright headlights are activated) as if failed to light up consistently when the bright headlights were activated by the button in the footwell. Also done at the service was a battery cutout switch installation in the trunk compartment.
I doubt that the cutout switch is involved but I can't help but wonder if the wiring for the dash bright light indicator could be shorting the wiring for the turn signals. I'm not a RR electrical mechanic so I don't know the schematics or if this is even possible...
And if not confusing enough… I have noticed a possible (?) correlation with the fuse blowing after one of the dash lights on the panel on the left side of the dash (the panel that has brake 1, brake 2, parking brake, etc) is illuminated. As the car tends to sit for extended periods it is not unusual for one of the brake pressure lights to light up for a few seconds after the car is started.
The fuse does not blow every time I run the car, but it is frequent enough (at least 2 out of three starts - and always after sitting for more than 2 days) to be a nuisance.
Any suggestions? None of the other lights are affected, including brake lights, reverse lights, headlights, hazard lights, or any other interior or trim lights. I replace the fuse and all works fine, until the next time I start the car.
