2001 Toyota Tundra Battery Light On

If you dont know how you can go to a shop to get it tested.

2001 toyota tundra battery light on. As your Tundra begins to eat through the voltage stored in the battery the headlights will begin to fade. All seems normal except the light staying on while running. My 2001 Tundra with 175K has been working well but last week after the truck had not been used for 3 or 4 days I discovered that the battery was dead.

Battery failed load test and was replaced. Charging was 139V after battery replacement. I have a full charge on the battery and have cleaned the corroded terminals hoping this was the problem.

Asked by kajudad in Fairfield CA on January 17 2010. I would have checked that before just swapping the battery. 2 May 16 2007.

To narrow down the problem you would put a multimeter set to the highest amperage it has in series with the battery and remove the main fuses one at a time until the current drops to approximately 02 A or less. The light itself is a warning system built into the vehicle to alert the driver that there may be necessary maintenance needed. Service type Battery Light is on Inspection.

The battery light comes on when it detects that the voltage in the battery is too low. Anyone out there had this problem. Seen it a million times.
