Ok, so my mum owns this nicky little 2006 Ford Ka, which due to her health problems has been idle for around 6 months. As my trusty Mondeo shed is probably about to expire, I thought I'd get the Ka going again and use that. Unfortunately, it's being a bit sulky and refusing to start.

First attempt: Nothing. Battery obviously dead.

Second attempt: Tried to jump from Mondeo. Electrics all fired up fine (radio, lights, digital odometer, etc) but when attempting to turnover it tries but immediately fails. After the failure the electrics all die and won't wake-up again unless I disconnected the jump leads and reattached.

The obvious thought is the battery is just totally F'd in the A and there isn't enough life in it to get the engine to turnover. Now, before I go and spunk some hard-earned on a new battery, is there anything else I should consider?

Fresh fuel?

Starter motor seized solid?

If I was you (and if it fits) I'd temporarily remove the battery from the Ka and fit the one from your car. I've known totally dead batteries to make it unable to jump start.

The tank was totally empty so dumped in 5l of fresh unleaded. Fuel pump starts up ok so I'm assuming, perhaps foolishly, that it's getting something.

Starter motor does go a bit but not long enough to turnover.

Jump leads will only carry enough current to support a failing battyer usually. You need to either swap the batteries over or give the Ka's battery a charge and then jump it as well.

That set of symptoms occurs when:

A)The terminals are dirty (they could be varnished; look clean but are not).
B)A short or loose wire on the solenoid switch.

I would take a wire brush to the terminals and see that no corrosion is under the the rubber back up along the battery cables. When this is the case, voltage flows (accounting for the electrics working) but the amperage is inhibited (accounting for all going dead once the resistance kicks in from the dirtiness). Good luck.

Hit the starter motor with a mallet or tyre iron.

If none of the others' suggestion works, connect the jumper in series to administer 24 volts instead of 12, this can jar loose a locked starter motor, if that is what it is. Mind you, this can blow a few fuses sometimes. smile

I'd put a known good battery on it before I did anything else. It has only sat for 6 months, so should just fire right up

I went on holiday and left my Octavia with a carPC still trickling on the battery. Came back and battery was utterly dead, tried jump starting from my dads Audi and still nothing. RAC man came round with a heavy duty jump start and that worked, long drive & touch wood no problems since! smile


A truly dead battery will not be jump started from another car...there just isn't enough juice in it & you'd need to keep both cars connected for a long time to get the old battery into some form of life (according to the RAC man).

Pretty much what I said - the leads won't handle the current without a face-charge on the battery. smile

yep remove battery and put in the battery from your car, or IF YOU WANT TO RISK IT

keep battery in car, leave BLACK cable attached.

connect up your jump leads back to black but the red from your car directly to the red on the KA bypassing battery

like I said, IF YOU WANT TO RISK IT

this will prove it is or is not the battery

I assume you have done the service bits just in case ?

Try connecting the leads as close as possible to the engine and starter. I.e put the black lead from you battery to the engine block. If possible get the positive lead on the starter terminal itself (unlikely I know, I've not managed this since jumping a '72 Viva years ago). Remember, you're trying to start the car, not charge the battery.
Failing that, leave them connected together, go and have a brew, then try again in a few minutes.

How big are the jump leads you are using?

If they are string-thn £3.99 jobbies they won'rt be much use on a very discharged battery.
A decent set of leads (probably around £50-£60 will get you a very nice set) makes a massive difference.

If not, sounds like dead battery to me too.
