Battery Drain Pointers
Posted: Sun Sep 08, 2013 11:59 am
Morning All
I'd appreciate some guidance from some of the more electrically knowledgeable members in identifying and resolving an excess battery drain.
I have a fresh alternator and Bosch battery, the charging system is fine. What I have identified, though, is a noticeable voltage drop on the battery over a day or so...
This morning, with an ammeter, I have measured a 120mA drain, with no key in the ignition. I understand that anything up to 0.05A is acceptable; I'm obviously over the limit!
When I remove fuse #1, there is virtually no measurable drain.
So, assuming it is something on the fuse #1 circuit, where should I be looking ? The factsheet shows this fuse as 'Cabin'; which I assume to be interior lights. None of the lights are on, so that should not be an issue, but I do have a Daewoo Nubira clock in the headlining above the mirror, which is fed from the courtesy light. Is this a likely culprit (I'll go and disconnect it to see), or are there other places I should be looking ?
