Feel an electrical saga coming on 'help'
Discussion
I've been running the Griff for a year now after its rebuild and thought it was time to look at putting the glovebox back in.
I reconnected the passinger courtesy foot light and basically got it wrong blowing fuse 11 for the lights.
After fixing that I noticed the red alternater light and the Yellow LED between the speedo and revcouter faintly glowing with no ignition on.
Key in and turn the ignition on to start car and the red alternator light goes out without the engine running (car starts ok).
Turn off and the 2 light glow again.
Disconnected the passenger light now but alt and LED still glow.
I've taken each fuse out 1 at a time and each relay out and the light is still on.
Took the 100 amp fuse to the fuse box out and still lit.
Removed 100amp fuse to starter out and it finally went out but came back on once refitted.
Have disconnected and reconnected the ECU as well.
Any suggestions on what to do next?

"red alternater light and the Yellow oil LED between the speedo and revcouter faintly glowing"
Doesn't make sense and is even more confusing as the alternator warning LED wiring works in reverse to what you would expect.
The Brown yellow wire on the back of my alternator reads about 1 volt with the ignition on but not running and then 13.5v once fired up which extinguishes the red LED. The yellow oil LED is simply switched by the oil pressure switch earthing the feed.
Maybe try disconnecting the wire on the oil pressure switch and pulling the interior light delay relay.
Good Luck
Edit - I've been thinking
Both LEDs have a positive ignition switched feed and earthed to illuminate them, therefore when your ignition is turned off something like the courtesy light delay is leaking a small positive feed to your dash and coincidently the passengers foot well light is actually wired from the back of the dash.
The alternators 13.5v output to the red LED extinguished the LED because the LED ends up with 13 volts on both sides.
