battery or starter motor – you decide !
“how would he know if the alternator was knackered ?”Posted 4 years ago
(there is usually a warning light on the dash but..)
I believe once you’ve got the car going, put a multimeter on the battery, it should be receiving a charge of around 14v, if much less the alternator dead/dying (more & its boiling your battery). Got to do this in a minute, fricken car wouldn’t start yesterday, hoping it’s the battery!
neighbour’s car won’t start (focus 1.6 zetec)
makes a click/knock from near the starter motor but no akshun
bump started easily but still won’t start from the starter
battery was flat recently and been recharged. Electrics all light up, central locking is working OK
Is this a battery thing or is it a starter thing ?
I’d like battery as it’s cheaperPosted 4 years agoDelSubscriber
should be ~14.4V across the battery when engine is ~3000 rpm.Posted 4 years ago
FWIW i had the aa out to jump my van when i left the interior light on for a week. after starting the very nice man diagnosed a fubar battery with his machine ( similar to the halfwits one, i’d imagine ). same battery 3 years later….
as others suggest give the starter a good twatting. they develop dead spots when they age so leathering them just moves them on a bit and they go again.
don’t make a habit of jump starting modern cars.johnellisonMember
Serious question, but whats wrong with jump starting modern cars?
Far more electronics in “modern” cars – if you got it wrong in the past, you might need a new battery or alternator diode; get it wrong now and you’ll fry all sorts of components = massive repair bills.
Most cars include instructions for emergency boosting in the owners manual, but it isn’t to be recommended regularly.Posted 4 years agoandrewhMember
Try hitting starter motor with something see if it starts

At first I ridiculed idea of hitting starter, but it worked on my previous car. Few moderate knocks should do the trick. But if that was the case then starter motor replacement is on cards.
Worked on the big mower for me, good hefty tap with a hammer and job done. Learnt that from Top Gear, useful factual car program (the rainforest one where Hammond beats his with a log)Posted 4 years ago
Why would jumping fry your circuits, Trail rat? I’ll state that done properly it won’t:
Connecting to another car is either the voltage of the battery if the other car’s engine is not running or the regulated voltage of the other car if it is. You risk absolutely nothing at all so long as the other car’s engine is not running and you connect plus to plus.
Edit: If you are worried about protecting the donor car then disconnect the battery, having first wired up a 9v smoke alarm battery to replace it if it’s a car that needs a reprogramme after a battery disconnect.Posted 4 years ago
