    Hi all

    Just a quick question... trying to start the motor... wont turn over. Battery is on the charger now to rule flat battery out... the multi metre had it at 12V and goes down to just below 11 when turning the key..

    It does appear to be making a clicking sound from the area of the left carby / Dizzy. I also noticed that the Ignition Coil was very warm ( car garaged ) and the lead that goes from the coil to the Dizzy I disconnected that and it was oily ..

    Any suggestions to get it started ?


    Cheers

    12V is flat but is probably not an accurate test if done just after attempting to start.
    If it were 12v then I would expect it to hit under 9 during cranking.

    Easiest is charge and retry.

    Clicking on carb is solenoids. Normal.
    If key had been on a short while then coil can heat up.

    Not turning over ... Battery lack of charge..bad terminal connections on battery, earth strap to body, earth strap to gearbox, starter.
    Corroded earth straps to gearbox.
    Poor connection IGN switch to starter, (tab connection on starter solenoid)
    Bad IGN switch.


    Quickest start a jump start.

    May need to recheck earth straps and resistance in ignition to starter circuit

    As Col said ^^^, you need a cranking voltage above 11.5 volts, which means a battery reading of at least 12.5 volts.

    Jump start, to eliminate poor battery, first.

    Has it been like this for a while or just a one off?

    Need to see if you are getting volts to the starter motor.

    Get some to turn over while you have a voltmeter on the solenoid

    Given history it's probably just flat battery.
    But if it has been flat for a while it may have deteriorated a bit.
    If it comes good it would pay to check it each month at least and give it a boost on charger rather than trust alternator to have done the job as alt can take a while to give it full charge.
    Best kept near fully charged.

    Just for the record, an alternator is not really designed to fully charge a battery like a proper battery charger. (Really you say? The regulator keeps the voltage at a level that is acceptable to fully top off the battery, but with normal loads in the system the actual voltage can be quite a bit lower). This is made worse by not driving vehicles often or for long and especially if it is flat enough to need a jump start. If you are not driving it much, install a battery disconnect terminal on the negative side of the battery and turn it off when you park it up for a while. Also connecting it to a charger every month or so will keep the battery voltage up and extend the life of the battery.

    That makes sense and could be the reason I have had a short life out of most of the batteries in my wife's pt cruiser. She usually does short trips to and from work.
    A couple of weeks ago I put a battery in. I will make sure I put on a charger every couple of months.
