2000 Toyota Tundra Battery Light On
I have a full charge on the battery and have cleaned the corroded terminals hoping this was the problem.
2000 toyota tundra battery light on. When I went to go purchase a new one from the dealer it was 950. Anyone out there had this problem. Discussion Starter 14 Jun 24 2014.
What is ECU in Toyota. Tighten the cable back on to the terminal. 06 toyota tacoma with 126k battery light came on hooked up DVOM charging 138volts with the light still on.
It is trying to warn you that there is an issue with the charging system. Lets diagnose and repair the Toyota Tundra 4 wheel drive system. Asked by kajudad in Fairfield CA on January 17 2010.
If the light is flickering in a very irregular pattern check the fuses belts all wires and connectors for corrosion and the dash bulb itself. Ya 75k is a little low for the alt to go out. So I went with a used for 150 lol.
Toyota tundra weird electrical problem draining battery while I sleep 2004 Toyota Tundra runs and cranks great but when left overnight wont turn over and i have to jump it. Unscrew the negative cable on the battery. If your alt is putting out say 135 volts but you still only see 11 or 12 at the battery post the cable between the battery and alt is dropping voltage.
If you didnt see a battery light and now the vehicle is dead when you go to start it the first thing that you need to look at is the battery. When the battery drains when parked the odds are that its the battery itself. All seems normal except the light staying on while running.
