Thanks wheels,
You were absolutely right, so I recharged the battery over night on the trickle charger put it back in showed up again at 13.1v,tried to bridge across the solenoid that quickly drained the battery and the odometer went out, hooked up the secondary battery off the car using leads bridged again and bingo fired up, seems to me the battery is definetly gone and might also need the replacement solenoid, idling now alittle Rough and also the screen on the odometer is going wild switching around and the settling on the battery voltage display going nuts eventually just shut down on its own...
Not sure what's happening but I'm gathering it's all to do with the weak ass battery now.
So ordered a new battery and will go from there..
Keep you posted..
