My Saab 9-3 is stuck outside my house and it won't start. When turning the key I just get two loud clicks and then nothing. All lights/ dash lights etc work ok. I'm not convinced it is the battery but I guess it could be. My internet searches suggest starter motor or corroded wiring potentially. I can't seem to see anything.

I have no AA or equivalent cover. I was thinking of calling a mobile mechanic, I'm in Leeds. Any ideas?

It sounds like the battery.

Got a voltmeter, or a mate with one ?

I don't but I do have a trickle charger. Worth a go?

If the battery's died, then trying to re-charge it will have no effect.

Worth spending a fiver on a simple voltmeter and checking the battery condition yourself ?

Can you run the A/C?

If the batteries dead it wont be able to power the compressor for very long.

If the A/C blows fine, then I'd look at the starter....

Didn't think of that. Does the ac not only run when the engine is running though?

Umm, the compressor is driven by the engine via a belt...

Do the headlamps come on at all? If you can work out where the starter is can you give it a thumpn with a spanner?

If you have another car, camn you try to jump it? Or bump start if you are on a hill. I have a battery booster pack that has saved my bacon a couple of times!

You'll no doubt find something suitable for less elsewhere, but Halfords do a simple multimeter for about £8, or a one-trick battery voltage tester for £14.50.

If you get to know the basics of a multimeter, they are very useful to have around.

Happy to tt the starter with a spanner laugh

Thanks for all the help guys, I will obtain a multimeter in the morning and see what it is reading. Lights do work.

What niggles me slightly is my brother in law (mechanic located some distance away) investigated a rattle/ clunking noise when my missus was up near him at the weekend. He "moved something out of the way of the exhaust" which has solved the clunking... I just hope no vital earth straps inadvertently messed with.

We'll see. Multimeter is a good test. If the battery reads low I'll order a new one online.

£5.90 in Toolstation if there's one of those nearby too http://www.toolstation.com/shop/Electrical/Electri...

Do the lights go dim when you try to start the car?

A simple test of the battery is to switch the blower fan to max. If that works then turn on the lights as well, also try the wipers and windows - if everything works as normal then it's more than likely to be a duff starter motor, dirty solenoid contact or (if you're lucky) just a loose cable.
The clicking you can hear is the starter solenoid (see picture) which is like a beefy on/off switch or relay for the starter motor.
You can take this apart to check the contacts yourself if you're into DIY. Failing that, a replacement unit isn't very expensive.

Connect the negative terminal of the battery to a good earth on the body with a jump lead. This will show if it's a bad earth or not. Had a very similar sounding problem on an e36 once...

Really you want to do this with the lead from engine or box to battery -ve.

You're right, try both. In my case it was the main body to engine earth strap.

When our 9-5 did this, it was a dicky crank sensor. I wonder if the 9-3 has the same (relatively) common fault?

Do they click though? In my experience a crank sensor usually sees the engine turning fast but not firing because the crank sensor is not reporting seeing the pulley move
