2013 Elantra One click no start Sign In

Hi all!

I have a 2013 Hyuandi Elantra with 140k miles.

One night when it was cold out (5 degrees f) my car died in the drive through. The headlights started to flicker, my power steering would cut in and out randomly, and my ABS and traction control system lights came on.

No worries, got a new battery, got the alternator tested, and it measured 14.5V with the engine on.


Two weeks later the same thing happened, except now, it won’t start. It is just one click and no start.

I measured the impedance between various connections to the battery and the impedance from the - terminal to ground is <0.2ohms which is great, and the impedance between the positive battery terminal and the battery terminal block is 0 ohms so I know the car is getting power.

It’s weird because after my car dying I could jump it ant it would work, but now, no jumping will start it. Just one click, no start.

Any ideas on what I should do?

No, you don't know that. All it takes is one strand of a giant cable to show 0 resistance with an ohmmeter but there is no way that would carry current to crank the engine.

When you are looking for high resistance in a circuit you need to perform a voltage drop test on that particular circuit. The way that is done by attaching one lead of a voltmeter to the source and the other to the load and then energize that circuit. The meter should read less than one volt.

Start by checking all connections from battery terminals at each end and connections at the fuse box.

One click, new battery and now won't take a jump start?
STRONG chance IMO you have a seriously bad U-bolt or right there another connection on the battery or it would do better with a jump. Only other is the starter motor end or engine block end of "battery" cable - large gauge one.
Single clicks are a give-a-way to me you lose almost all power, but not enough to make a solenoid flutter when it's asking for ALL possible (AMPS) for cranking,
