Ron has your car got the one 16-way fuse panel?
Like this? 16-way
On mine fuses 11 to 14 are constant live.
Fuses 15 & 16 are for High Beams.
Charlie has 2 8-ways which I have not seen before.
So his top fuse panel, 8 & 7 correspond to my 15 & 16.
His top fuse panel 6, 5, 4 & 3 correspond to my 11, 12, 13 & 14.
Leaving either your illumination / control dimmer on should not effect battery drain with light switch off.
The same with the blower or icing switch, they should be live when the key is in accessory or run.
That is if the wiring is correct.
Let us know what you find out.
