Why does my Toyota Tacoma Battery Light Come On and off?
My 2006 Tacoma battery light intermittently came on and off, the battery and alternator tested good. There are three wires that come off the plug in of the alternator. I unwrapped the wire harness and found the white wire had corroded on the inside of the wire and it broke in the middle. I cut out 3” out of the wire to eliminate the corrosion.
What to do if your Toyota Tacoma alternator is bad?
Set it to read voltage. Specifically, you’ll need to set it to 20V DC. With your Tacoma turned off, you’ll connect the negative side of the meter to the negative battery post or wire. You’ll then touch the positive side of the voltmeter to the positive battery wire.
What’s the battery voltage on a Toyota Tacoma?
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 does my alternator not turn on the battery light?
That battery is likely at or near the end of it’s useful life. 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).
