I bought a 93 Ls400 in July, pass few weeks I've had battery drainage issues. New battery and alternator checked out good. Using a meter I determined the drainage (while car is off) is coming from the dome circuit. When fuse it out the battery stays good. When fuse is in, the battery is drained within 6-8 hours and won't start. Nothing is is being left on that I can see. Any ideas on what it could be on this circuit that is causing the drain?

This circuit is one of the bigger circuits with lots of functions on it. Nothing has been done to modify anything to cause this problem. It just appeared out of nowhere.

Appreciate any help with this. I haven't gotten around to checking everything on the circuit yet, plan on doing this over next couple of days. I was just curious if anyone knows of a similar problem to help me narrow down the issue.

THANKS!
