Jesse battery I think is about a year old

Head unit could be hooked up to the constant +12v, slow drain

I'll reset the battery tomorrow

wiring has been triple checked. Gav can confirm.

If it is battery, i'd be surprised if the LCD didn't light when the central locking worked, but who knows how many amps these elements need.

yeah it is wired with a switched 12v source (acc).

going to check the fuses tomorrow also.

the switched 12v source is DEF NOT wired to the constant 12v source.

Just replaced a blown fuse.. still nothing.

Disconnected the battery for 10 mins. still nothing..

may be clutching at straws and a random idea, could the earth be a dud? Can check with voltmeter, obviosuly +ve on the battery and -ve on a body panel.

Eh I doubt it.

Will test anyway...

Might sell up after this is fixed. A few to many gremlins for my liking.
