I'm getting a dead battery after my truck sits overnight. I'm also getting shocked when I touch the door.

Question

I guess I've got a hot wire grounding out on the vehicle somewhere. Any suggestions on what to do or what else could be going on? It's a 2002 Trailblazer.

Answer 1

are you being shocked while in the truck getting out or outside getting in? if inside getting out do you have power seats? check that no wire is grounded on the slide rails. did someone change your oil recently? check under the hood. a good start point is to look were there has been work done recently. if you ran over something, look under the truck, sometimes all it takes is a paper box being ran over to cause you problems.

Answer 2

Sounds like you have a short to ground. If you have a multi-meter and a friend, set the meter on DC volts so you can read between 0 - 20 volts. Place the meter positive probe on the positive terminal of the battery and the negative probe on the negative terminal of the battery. Have your friend carefully watch the meter and make sure all electrical accessories on your car are turned off, including the dome light.

Now, one by one, pull each fuse from your fuse panel and then push it back in again. If there is a short, the meter voltage reading will go up when the bad circuit fuse is pulled.

Once you've identified the bad circuit, then the real fun begins. You will need to trace the wiring to find worn insulation or a faulty electrical device. A lot of times these occur where wires pass through metal (i.e.: firewalls) and with moving parts like switches.

Good luck finding that...

CCrider has the right idea. But I'm lazy, so I have an easier way (almost) using a test light and a fully charged battery, or leave it on the charger, either way, find a good ground. Next stick your light's probe to a couple of the terminals on the fuse panel (you want the dead side) now find the side that isn't dead (the light comes on). That is your circuit that is faulty. You still have to chase out the wires yourself (told you I was lazy). Exclude permanent hot circuits, ie. radio clock, lighter etc. That will help narrow it down. BY THE WAY, do you have an AMP and a speaker system? Check for a rubber grommet around the HOT cable going to the AMP. It may have chafed through. Good Luck!

on no account enable the clamps touch. you're able to desire to relatively blow up the battery. whilst bounce commencing a automobile, the main secure and maximum cautioned thank you to bounce the vehicle is: a million) connect the black clamp to the damaging of the coolest battery 2) connect the crimson to the useful of the coolest battery 3) connect the different crimson clamp to the useful of the lifeless battery 4) connect the final black clamp to a good floor source (in many circumstances the physique or engine block). it is the main secure thank you to bounce initiate a automobile. make useful the floor source which you p.c. is an unpainted floor. whilst working with automobile batteries, theres continually a threat to get shocked. yet once you do each and every thing the type you ought to, you wont get shocked.

Answer 5

My ford ranger was doing the same thing and I had a hot wire scraping under the truck to the switch which shuts the fuel off in case the truck flips upside down

Answer 6

Get the battery tested at the auto supply. Getting shocked has nothing to do with your battery unless you have a dc / ac converter hooked up wrong. The shock is generally static electricity that builds up in you. 12 volt batteries are dc and that don't shock you.

Answer 7

check the ground wire that goes from the battery to the body of the car

Answer 8

Its unlikely that that battery is causing the shock..Chevy has a known problem of brake light staying on. Could be a defective alternator.

Answer 9

Your positive are negative clamps could be loose or making contact with the hood or fender.
