Why is the battery light on on my Toyota Tundra?
2001 Sequoia alternator went out / battery light on / lights dimming / tested bad. Got a new one at Auto Zone – gave me 14.xx volts at the battery posts. Headed out of town on a Boy Scout campout and it died (thanks to frequent jump/drive/jump/drive/repeat, we got there and back).

I have a 1997 Tacoma V6, since last week my battery light started to come on and go off at random times. hooked up a volt meter to the battery and it read 14.19V while running and then luckily the battery light came on again and noticed the voltage dropped from 14.19V to 11.9V all within 5 minuted or so.
Why is the battery light not turning on?
A weak battery or working charging circuit won’t turn on the battery light. Since you pretty much ruled out the alternator I would make sure to check your fuses. IIRC there are 2 fuses for the alternator (will check my diagram later). If your fuse check comes back fine, you likely have either a cluster problem or wiring problem.
What does load test on Toyota Tundra mean?
A load test is just what it sounds like, tells the alt to work hard. If the alt kicks it up but you dont see that increase at the battery, look back into the cables. You need to check the Alt output at the “B+” post on the back of the alt, not just at the battery posts. See exactly what the alt is putting out. Work your way out from there.
