so my bosses daughter left her lights on in her eg coupe. they assumed the battery was dead bc nothing had power. tryed jumping it and nothing happend. so they purchased a new battery and still nothing works.


ideas guys? thanks alot

 

Check ALL large fuses and main ground connections.

 

how are the wires to from batter?
battery fuse?

 

make sure grounds are all tight. could be your ignition relay.

 

were is the ignition relay? thanks guys!

 

ummmmmmmmmmmmm i still cant find the relay.. even in the book...

 

main battery fuse,my guess is no ground would come lose from just sitting

 

all fuses are good. the wierd thing is when you turn the headlights on...nothing happends. but when u hit the brakes the brake lights come on. nothing else has power.

she also tells me last nihgt she thinks they hooked up the terminals wrong when they tryed to jump it... any ideas?

 

has to be a fuse. check under dash and under hood. main relay as well if it wont start

 

all fuses under the hood are good. all fuses under dash are also good. i pulled each one individually.

the car will not start. seeing as it wont turn over. when the key is turned to acc or anything no lights work. radio doesnt work.

only the brake lights

 

when u turn the key on nothing lights up right? not even any dash lights? can you hear the fuel pump prime?

 

nothing has power. no fuel pump. no dash lights. the cel light doesnt blink like it normally would.

and your a 100% sure the new batter is good and the connections to it are good. hell if ur brake lights are lighting up i have no idea.

 

they bought a brand new battery. yea i am puzzled. i have never heard of this...

if the fuses under the hood look good could they still be bad?

 

IF ANYONE WOULD LISTEN.the brake lights turn on. so the system has juice .it just doent go where needed.what car is this in.look at all the large fuses that bolt i to tthe fuse box under the hood.check all the wires like people said.just to be safe try checking the wires for the igtion switch.i had this problem with my old vw.it may have burnt a wire out when the y hooked the jumpers the wrong way.good luck man.

 

as stated. checked all grounds. all fuses.

 

bump

 

im sure you missed a ground man.

 

missed a ground. how could a ground come unhooked from leaving the lights on?

 

It's either you missed a ground, or overlooked a fuse.

It's usually the main fuse under the hood. Under the hood means the box on the passenger side of the engine bay near the firewall. Those will go out if there is a short or if the jumper cables were hooked up backwards when trying to jump the car. And that is most likely what happend in this case. The one that goes out should have been the 80amp BLACK fuse. They have a clear top to see a blown fuse. Make sure you check again.

 

You need to get a voltmeter on the 80A and 50A fuses under the hood, there should be 12v on both sides if the fuse is good.

Try jump starting it again, but connect the negative cable directly to something metal on the engine or tranny, and the positive to where the large wire on the starter, then turn the key. This bypasses the battery cables.

Put the car in nuetral and touch the positive jumper cable to the spade connector on the starter, this bypasses everything!

You're not doing your bosses daughter, are you?

 

hahaha... no

but i am 100% sure every fuse in the fuse box under the hood is not blown. and i pulled every fuse under the dash aswell. i tryed connecting jumper cables from the ground on the battery to the tranny. and to the frame. nothing turns on. except the brake lights.

 

hahhaa.. yes. Its a ******* fuse or shorted circuit , look harder

Exactly.

After they jumped it, is that when EVERYTHING stopped working? Did they have to jump it "twice"? Here's what you do, if you are SURE you have ZERO shorts, which could be in a number of places. I had a short from my ghetto wireup of the "Gear in park" trick when I swapped from Auto &gt; 5spd. You buy a new damn 80amp fuse, and replace the old one. Then see if it works. Regardless of if "you checked it" or not.

 

you checked the larger fuses ? the ones that are screwed down right ?
