SPI rover mini, battery fully charged, horn Headlights radio, indicators all run at full speed.

Turn the Key and 1/2 Rev, and out of puff....
sounds like a very flat pattery, but its full charged,

tried to push start, rotates freely but no kick..

what could it be....

yes a crystal ball view would be good...but you are getting fuel?, have you tried pressing the fuel cut off inertia switch?

Another try could be you could try is, soak a cloth with petrol. During starting the engine, put the cloth to the inlet filter housing( to richen the fuel).
If this works well it could mean that your temp sensor/wiring got problem.

So it's not cranking over? Try taking the spark plugs out and see if it cranks over normally.

Could it be a faulty battery terminal or connection to the starter motor solenoid or the earth strap?
A little load on it, then it breaks down. Check if any of these points are getting hot to touch.

The starter engages for 1 second and then there is a clicking sound and nothing happens and the clicking stops

Start your checking where the power starts! at the Battery terminal connections. Make sure they are clean and tight.

Put a voltmeter across the battery posts when you crank it. If it goes down to 8V or so the battery has an internal problem. It it stays around 12V you have a connection problem, somewhere.

The clicking is the solenoid in the started motor opening and closing due to poor current. So my previous suggestion is pointless haha

All terminals clean and tight. Just gave it another attempt.. Loud clicking from Starter motor,( Poss Solenoid) turns about 1/2 rev and starts clicking again, this repeats as long as I am turning the key...

How do you jump start from the engine bay and not from the boot, where does Pos and Neg go under the bonnet..???

This may bypass the bad connection and at least know it starts OK.

_________________

It does sound like what Doc was saying, the voltage is dropping as you take charge from the battery which causes the solenoid to chatter like it has been. Your battery is either flat or its cactus.

You can connect your jump start leads from the battery in the boot no problems. If the battery terminals are even close to tight it won't carry on like that.

All garage work involves equal measures of enthusiasm, ingenuity and a fair degree of irresponsibility.

Not sure if already mentioned, but a dead starter motor can also do what you're describing

My Rover did this when the battery terminals had too much corrosion on them & the second time when the battery was dying.

Take the battery out and get it tested at your local auto shop. Most places are free.

My money is on the battery. My car did the exact same clicky thing yesterday.
4 hours on charge and all good again.

If you're sure battery is fine, there's an earth strap from battery to body, and one in the engine compartment under the top engine stabiliser. This is a pain to get to, so to test if thats cone put a jumper lead on a steel part of the block and back to the body somewhere. Check terminals are tight too.

If it cranks 1/2 a turn then its not the solenoid. Rule that one out. I think it also rules out condenser, coil etc. My money is on the battery connections, I know you say they are on firm and all that but behind or in the clamp it may be a breaking down connection. If you can get someone to wiggle each cable separately while you crank it you may find it works with the cable in one postiion but not in another. The fix is then the obvious. Hope it helps...
