    Hi,
    Have just got back from a 20 mile trip in the rain and parked up...engine off, all ok. I then decided to move the van forward a bit and stuck the key in, turned it and sparks flew down from under the bonnet. I tried it again and now the engine won't turn, just a clicking noise. Has anybody got any ideas what could have happened or caused this?
    Peugeot Boxer 2.0 Deisal Autosleeper Symbol 2004, 23,000 miles.

    HELP PLEASE!

    either your starter has shorted or your battery has expired have you opened the bonnet to see if anything looks obvious?????

    Probably popped the fusible link. Batteries are quite tight on these, and it won't take much for a loose connection to arc across.

    Check that the battery is not 'swollen' or otherwise damaged. Then check terminals and ancillaries are all tight and have no arced out.

    Next, check starter motor to see if connections are intact and tight.

    There will be a loose lead or wire somewhere. Have a look at the fuse board too.

    Is your engine battery under the bonnet?

    If so I would check the terminal connections are tight.

    I suspect a starter motor problem.

    Can you switch off everything, put vehicle in 1st gear (handbrake off) and see if you can "rock" the van a little (a couple of inches) to free off the starter cog which might have got stuck in the flywheel teeth. If you can turn the engine over a little way and especially if you hear a slight "clunk" of the starter motor thingy freeing off... try the engine again. (out of gear of course.)

    Others will know more.

    JJ :Cool:

    Sorry JJ, but...

    NO NO NO NO!!!!!

    Investigate or get investigated the spark source before doing ANYTHING else, especially putting the key in. As it appears at present to be started related, FIRST task pronto needs to be disconnecting the battery, earth (negative, typically black) first.

    Then follow earlier checks.

    One word, FIRE...

    please do nothing untill you have disconnected the battery, make it safe then look for the problem, 99% of electrical fualts are mechanical problems, i would do as others have said but make it safe first.

    Yes, the earth bonding cable from chassis to engine block underneath.

    :thumb:Thanks everyone for the advice / replies, I managed to start engine only after 'rocking' the van in first gear and spraying the earth strap connections with wd40. After turning off I again then tried to start it but again sparks and 'nothing'.
    Do I presume it's the earth strap?

    Don't assume anything, get someone to carefully look where the sparks are coming from.

    BUT sparks and WD40 do no mix, it's VERY inflammable. I once sprayed it on an arcing plug cap. Never again. It was like a flame thrower. Got away with it though.

    I love wd40
    I should think, over the years, it has earned me thousands...

    people think it repels water.. well yes, but only for a short while then it attracts and absorbs it.. If you want to use WD-40 for anything other than cleaning jobs ( from work tops to hands .. ) you MUST refresh it every couple of weeks or so else it will do more harm than good..

    If you wasnt to use something to stop corrosion use ACF-50 or similar.
    It is not cheap but does actually do what most folk think WD does, andddd.. it is not highly flammable as Brian rightly points out


    I would suggest you:

    Open the bonnet and physically wiggle all and any big thick wires you see especially around the battery area

    Do not go made, but give each a firm tug

    Leave the bonnet open and get someone to try to start it while you watch to see exactly where the sparks are coming from

    I have to agree John, if my workshop manager finds WD40 in our workshop he goes spare...:thumb: Griff
