You need to check your ignition system, the problem isn't with the battery, obviously.
Does the engine crank but not start? Or does it not even crank? Based on the information you gave, you could have a bad starter or weak battery. Dead battery. Recharge it or get a new one.
Probably a bad ground from the battery to engine/body.
iT CAN BE EITHER FUEL OR FIRE. taKE IT TO A GARAGE.
Check headlights and dashboard lights first. If no/minimal power for the lights then replace battery.
check the starter, or maybe check the battery may be enough voltage for lights, but not to crank the engine over.
Sounds like a loose wire somewhere. Check the battery connections then other ends of the wires.
could be bad cells in the battery, but my bmw ended up having a seized motor, starter was engaging and clicking because it couldnt turn the engine. try putting a socket on the engine crank pulley to see if engine will rotate
When you say 'crank over' are you saying the engine won't do anything? First check your battery and then your starter or starter solenoid. You can turn the crank to check if the block is seized or not.
Sometimes, brand new batteries need to be charged for a while before they have the power to engage the solenoid/starter properly. The battery may have enough jucie to light up the headlights and run the stereo, but not to crank the engine.
check the ground to the engine block
AnswerDim lights and lots of clicks is an indication of too low a charge on the battery. When jump-starting, allow the battery to be attached to the jumper cables for about 5 minutes before trying to crank the engine. If that fails, check for loose battery cables at the battery, ground, or starter. If all connections are good, then the battery is too far gone and must be replaced. Note: You need to find out why the battery discharged - did you leave the lights on? is the alternator bad?.
The battery has insufficient power to crank the engine but enough power to power the lights. The starter motor needs considerably more power than the headlight bulbs.
