Battery Issue?

Marine grade breaker, marine grade fuse block, relays, proper grounds, etc.
Tested and confirmed - zero parasitic leak/draw.



What am I testing "amp draw" for?
4x aftermarket horns...which are used once (for 3 seconds) a decade?
1x LED light bar, same as above.
A few LED/low amp interior devices which are seldomly used as well.

My wife ran 1000+W RMS stereo in her 2005 4Runner, and I had to replace the OEM, Japan-made, battery..........after 12 years!
It ain't me bud, it's the sh** OEM Tundra battery, as described in post(s) above.

 

Testing for amp draw when in use and powered off (parasitic leak) is what I was referring to.
Looks like a clean wiring job. Thats on top of the air filter housing?

Hope you have better luck with this battery.

 

No; top of the pass-side fuse box.

Thanks.
