Anyone have tips for troubleshooting key-off load on my 87 560SL?

Current draw is about .72 amps when the car is not running...resulting in a drained battery when the car sits for a day or two. I take it that value is higher than it should be.

I have narrowed the draw to the "always hot" circuit 30...fuse 12 on the fuse panel.

Obviously I can pull the plug on the antenna. No I don't have any lights on.

What connectors can I pull to check:

- trunk/dome lights
- hazard lights/turn signals
- alarm system
- central locking
- radio
- "warning system"
- clock

What is the easiest way to check this circuit?

best,

Dave
