2002 Battery Drain

[19963.4lsr5]

So, this morning my battery was 12.1v. So I drove to the local interstate distributor / warehouse and they tested my battery as bad and I replaced it.

I thought your battery sounded way too low.
I wonder if someone with a 3rd gen 4runner could do me a favor...
disconnect the neg cable from the battery and connect a 12v test light between the negative post of the battery and the other end to the negative cable just removed. And see if the test light lights up. and if you pull the DOME fuse - if the light goes out.
Maybe the DOME fuse is intended to work that way as opposed to telling me I have a short?
If this helps: I have a 2002 4runner Sport with a factory alarm.

It would save me from chasing something that may be as designed. If anyone sees this request....I may need to make a new posting directly related to this request. Thanks!

I would do it if I wasn’t so close to vehicle inspection. I don’t want to have all my readiness monitors unset. Someone with a 01 or 02 should do the test to have similar control systems.

TTT.

2002 just started with a weird battery drain. Once I get battery charged I can do some troubleshooting.

In the meantime, anyone else track down any battery drain issues?

Charged the battery overnight with pos and neg disconnected.

Load tested battery and it is good. Battery after load test was 12.7v.

Connected positive, put multimeter in series with negative post and negative cable for parasitic draw check. It is an auto-ranging Fluke 107.

7.5amp draw...doors closed, key out of ignition, let sit for 30 minutes before checking.

Pulled fuses in engine compartment one by one. Mirror heater (10A) was 3.0 amp draw of the 7.5, and the defog (15A) was about 4.5 amps of the total 7.5 draw.

There was still 154 mA (.154 A) draw with both fuses (mir htr and defog) pulled.

Durk Rule #6?

Going to check the rear liftgate wiring when mother nature cooperates and stops raining on me.
