Current draw with the ignition off

[Scott Montgomery Lurker Find all posts View Profile Close Scott Montgomery]

I Have an issue draining the main battery over night, there is a 1.5amp draw with everything off.
There is a faint spark when I connect the battery.

I have checked all the usual suspects, interior lights, glove box and so on.

I have disconnected the dual battery isolator and turned over everything I can think of.

Any hints what else it could be?

Start pulling fuses in the main box until you see it disappear...

Thats 18-20 watts constant draw. I'd start with added accessories and then look further. I highly doubt its a light because it would be bloody bright!
