Battery drain.. Shunt fuse?

The parc shunt has two positions: normal and park. In the latter some electrial systems are disabled in order to prevent battery drain while the car is parked for an extended period.

So that is a red herring.

It sounds like you witnessed the BSI powering down as it should.

Guess: previously something was keeping the BSI awake, e.g., it thought a door was open.

Can I ask: exactly how are you measuring the current? We had a 307cc that went flat if not used every day and never got to the bottom of it.

Can anyone recommend a clamp meter?
