Tundra electrical issues

Asked by tecsol1111 Oct 17, 2020 at 07:16 PM about the 2004 Toyota Tundra V8 Limited 4 Door Crew Cab 4WD

Question type: Maintenance & Repair

Evening folks, have a real strange issue here, was putting a new exhaust
system, manifolds back.



My battery was dead when I finished and threw the charger on for a day.



Next day I see that the head lights are on, no parking lights(stalk switch is
turned off), dash trouble indicators, VSC, seat belt indicator, air bag indicator
and such are all on, WITHOUT A KEY IN THE IGNITION OR TURNED ON!



Truck starts, runs and turns off normally....



Also with the key off and out of the ignition, the power windows will work if
pressed...



Have gone through my service manual and schematics but don't see
anything that sticks out as the issue.



Disconnect the ignition switch and nothing changes.



This is really breaking my butt off!

Have checked the archives and don't see the same issue mentioned.



Anyone else have this issue!!!!!



TIA!

Retrace your steps from the exhaust system replacement. Sounds to me like a ground wire got disconnected or burned off during or right after the exhaust system work. Hope that helps! Jim
