I'm trying to find why the battery dies after a few days of not being run. So I disconnected the negative battery cable and hooked up the multimeter in series (in Ammeter mode) between the negative cable and the negative terminal on the battery, and there's a current draw of 2.4 Amps. No wonder it dies so fast! Max draw from the factory is supposed to be 35 mA (0.035 A).
So I start pulling fuses one by one and checking the current. Once I get to the CTSY fuse, the current draw drops to 0.18 Amps. I disconnect all the other fuses, and its still 0.18. Disconnect my Gentex mirror, and it's down to 0 Amps. Plug in everything EXCEPT the CTSY fuse, and it's 0.18 Amps. Plug in the CTSY fuse, back to 2.4 Amps. SO I think I've found the circuit on which SOMETHING is drawing a lot of power.
What on this circuit can be drawing so much power? I'm going through my service manual, and a lot of stuff is hooked up through this circuit.
EDIT: Found the 'problem' I went through the diagrams and saw the interior lights were on that fuse, and I was testing the circuits with the driver's door open so I could keep pulling the fuses. Whoops
Closed the door and it was back to 0.18 Amps. Unplugged the Gentex mirror, and it's down to 0.02 Amps (20 mA) so the problem is the mirror. Maybe a newer design one doesn't use as much power? But now I know I can just unplug the mirror if I'm not going to drive it for a few days.
