the wiring or the fuse panel itself... time to break out the multimeter probably ignition switch Everyone should have a manual, and the library should have a professional shop manual available for copies in the reference section (FOR FREE)...read up and fix 'em like the pro's...! :) Dave
Make sure that you connected the battery cables properly. The red cable goes to the positive side(+) the negative or black cable to the (-) side.
Defective, corroded, or loose battery cable.
If you are 100% sure nothing is on pulling power from the battery and it will not hold a charge then the battery has a dead cell and must be replaced.
nothing works and I replaced the battery. to the fob
First - could be an intermittant problem with the electrical wiring or starter motor. Second - get a new mechanic
If you mean like AA or AAA, nothing. Absolutely nothing happens. If they both have an electrical current running, I don't know, it might be dangerous.
Bad starter solenoid? Loose or corroded battery terminals? Weak battery? Bad neutral switch?
There is nothing to reset except the radio presets and the clock.
Nothing, as long as they're both the same voltage. The 18 Ah battery has just slightly more power. It will work perfectly.
Can be a dead battery, defective starter, loose or corroded battery connection, or blown main fuse. If nothing comes on when you turn on the ignition switch and your interior lights are not working it is not the starter.
If the post has actually come out or is loose and wiggles there is generally nothing possible that can be done to repair it, the entire battery will need to be replaced.
Yes, they most certainly do. Without a battery that would be nothing to store the electrical energy. Without the electrical energy you would not even be able to start the engine let alone drive the car. The battery supplies electrical power to all electric components within the vehicle. Without a battery the car is just a hunk of metal that is going nowhere.
