Won’t start or turn over

When I try to start my car it's making a rapid mechanical clicking noise, but the engine isn't turning over. What's going on?

Is it a K?

There's a long list of causes and a vast number of threads. And the cause of yours might be different from what has affected others.

Full search of the archives.

I recommend taking this logically rather than jumping to a a possible answer.

Do you have a multimeter and would you like the appropriate wiring diagram?

I thought 2020 was the year that was going to give me all I wanted. It turned out to be the year to make me appreciate what I've got.

A single click can be a puzzle. A rapid stream of clicks is almost certainly a flat battery. Starter engages, voltage drops, solenoid drops out, voltage recovers, starter engages ...

Yep, it was a flat battery. Stuck the charger on it and started no problem. Thank you all.

Well done.

Was there a reason for it going flat?

Can you check the fluid levels and top up if needed?

When it's charged I'd check the battery and the charging system by measuring the voltage across the battery at rest, minimum during cranking, and at 3,000 rpm.

Don`t use it enough?   No isolator?  Banners have short lives.

Could you keep an optimate or similar connected.
when checking voltage this may help.

That is a very useful chart.
