1997 BMW318I, new battery, all lights come on, on the dash, turn key and only a click noise is made,won't start engine.

Do you own a multimeter and a test light? Can you perform some diagnostics on the battery, continuity check on the ground and (+) cable and at the fuse box. Your symptoms sound like that of a low battery or poor electrical connection. Please write back with questions and new information. Good Luck.

First I would look for voltage drop of both end of battery terminal.not a look or seem tight . you have to do it (voltage drop) and terminal at alternator.
now does alternator charging. take voltage of battery
if the problem occur have voltage of battery taken
like I read your problem it looks like wiring terminal ground and positive
the noise you hear is probably low voltage to a relay and the dropping voltage make the relay switch inside relay cycling noise click or buzz

Hi eyansdaddy,
Sounds like a bad connection on the battery , check the earth cable on the battery and the one that earths the engine to the bodywork (at the bottom of the engine) if there worn or frayed it can stop the engine from starting. all the best Scott

The voltmeter should only go as high as 14-15 volts when the engine is running. I would check for a poor connection between the battery and starter.

blow horn, see if lights in dash light up then turn key all the way like you start car if lights go out and no engine clicks are anything u hhave starter probelms replace it

earth cable from body to engine and battery to chassis ,clean the connections and fit an additional cable ,also clean and grease the battery terminal

your battery isnt holding enough charge to crank the starter.thats what the clicking is. try charging you battery for a good 8-10 hours, if it still does the same thing you'll need a new battery.

did u have the alternator tested to see output get a jump if the car starts takeit to a auto zone have him test the battery and alternator for free

does it try to turn over if not it could be that the battery is dead if that not it then you mit have a blown fuse

Dont have a clue about the hazards but the connections on the starter could be bad
