fwiw, honda charge ~£64 for a battery
went over to my local one this morning and thats what they could do for me.

apparently the S2000 battery is the same as the new civics.
mine is the import. (import has the poles reversed vs the UK models)

Flat battery! Jump leads and another car should do the trick.

Definitely flat battery, the reason being is this:-

The starting circuit is split into two, low current and very high current. We don't these mixing and we definitely don't want the high current anywhere near warm, salty, fleshy things!

The solution is to have the starter button connected to a simple 12V low current circuit which when the starter button is depressed activates a solenoid, this solenoid is the 'switch' to the high current circuit which connect pretty much directly the battery to the starter motor.

The solenoid is activated by electromagnetism, i.e. when you apply voltage and current to the electromagnetic it energises and a iron rod flies out and pushes the contactors which connect the high current circuit. If the battery is low or flat (below 10V) then there is not enough current to hold the electromagnetic charge and therefore, the solenoid/iron bar rattles going up and down but not staying down to make the high current circuit.

As soon as this occurs, the battery goes really flat, no current means the solenoid de-energises, breaking the high current contactors, then you have lots more current, so the solenoid re-engages and makes the high current circuit again and the process repeats itself .

This is the machine gun noise you hear.

This happend to me about two months ago. Flat battery. Had just enough juice to raise the roof and put the windows back up (albeit very slowly) whilst I went to get it sorted.

A battery is flat at < 12.4 volts not 10, that would be a faulty cell.

Thanks all for you comments.

Got home from work, put the battery charger on for an hour and guess what..... She Fired Straigh Up.

Lesson learnt - Use the car more often!!

Thanks

Not really. The lesson to learn is you need to replace the battery or it will soon let you down again

The engine is high compression and it takes a lot of effort to turn it over.

Thing is, the battery was replaced in October

I used to do 20K a year in the car, but since i got a beater it only does 2K a year

Put a trickle charger on it when you are not using it. £10 on ebay. Will save your battery from discharging and eventually breaking.

exactly the same thing happened to me, flat battery
