I have a 2001 Chevy Tahoe that went dead while backing up and now doesn't recognize the switch
I cranked the Tahoe, it ran for 10 minutes. when I placed in reverse it acted
like it was going to go dead. I placed it back in park, gave it a little gas then
back to reverse to which it died. the key will turn, but no lights on dashboard.
I've verified charge on battery, and checked the ignition fuses, still nothing.
So what is the battery voltage you found? A fully charged battery shows 12.7 DCV and no less than 12.5 DCV.
it is 12.5- 12.6. I also tried to jump it off with a jump pack.
There is enough charge to turn it over. One other thing I would verify first is to check to see that there is power going to the small wire on the starter solenoid when someone is turning the key to the start position. Going dead tho, almost sounds like some bad battery cables, or connections. May want to look at that also.
If it wouldn't take a jump, check your charging circuit and battery cables as Rowe suggested. You may want to do a voltage drop test to starter.
would this prevent any of the lights on the instrument panel from recognizing the key turned on? the cabin lights come on with the door open but nothing shows that I have turned the key on. leading me to think that its a relay or the ignition switch itself. but i will check the voltage drop also.
The starter could be that bad that it could cause that.
