Bad battery, starting motor or both.
If the battery is bad, you may only hear clicks. It could be the starter, but I would check the charge on the battery first.
Possible battery, starter or connections/cables in between
Starter solenoid? Battery not fully charged?
Weak battery or poor connection - battery to starter. Possible bad starter.
This sounds like your battery.
Likely that your starting motor needs to be reconditioned/re-built
Try changing the starter.
Dead battery or a bad connection to the battery.
If you are talking about a car engine and battery then it is not the battery that is clicking. It is in all probability the solenoid.
That means the solenoid IS working, but power is too low to turn the starter. Check and if necessary clean or tighten the battery terminals. If still the same, charge your battery on slow for at least 12 hours, or get another battery.
the engine will turn over but sometimes wont start. it also sometimes dies while its idling. whats going on
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?.
start with checking the battery, next check the solenoid,next check the starter motor.then check ignition switch
Start with having the battery tested. Any auto parts store will check it for you at no charge. Be sure all connections are clean and tight before you start buying parts.
the relay or the starter motor is stuffed
It could be a dead battery.
Check your battery, it might be dead.
solenoids are what clicks, yes it will click if the battery is low.
Battery is dead.
You need to charge your battery or get a jump. Replace the battery or have it checked because it is dead.
Your battery is low. You probably has to replace the battery. Or maybe the starter motor solonoid is faulty
Slide it back into the battery compartment until it clicks (observing correct polarity !)
