Lights are bright but it only clicks when you try to start it

Try the wiggle test on your battery terminals and ground and positive wires running to/from starter watch for light fluctuation on car if there loose clean tighten and try and start if nothing suspected problem is stater proceed to test starter repost stater test and i will post diagram for ya too big for one post. And also try to jump start before stater test. hope this helps

If you can locate the starter and it is in a safe position,get someone to strike it with a hammer while trying to start(may have to repeat this several times).If it starts,it is most likely worn brushes,starter will need pulling out to do so,sometimes it can be the solenoid not actuating also.be careful if using a metal object to strike it,that you dont short out on the main cable to the starter solenoid
