Re: Slow electrical leak???
The standard troubleshooting approach for a static drain problem is to
charge up the battery, disconnect the positive lead, and attach an ammeter
between the positive lead and the positive battery post. If there is a
current draw, it will show up on the ammeter.
Two caveats at this point - start with the 20 amp setting on your VOM to
avoid frying it, and watch out for the current draw which may come from your
interior lights if you are doing this with the door open.
If you have a current flow, start pulling fuses and relays to isolate
the problem area.
