Have a weird problem with this one. Often, it will be completely dead in the morning. According to the mechanic the wiring, alternator, and battery are all in proper condition. Nothing we can see is still on at night. Any suggestions where to look for a fault?

I’s suspect a phantom current drain. Any good shop can easily test for this.

Also, suggest you re-post this the Repair forum section of CarTalk. You’ll get more replies there.

Repost this in “Repair and Maintenance” as George suggested.
