Changed over to a 40Amp swith mode and everything came good. Checked the voltage on the jump pack and it was down to 9volts. Put the battery on charge over night removed charger this am and the battery was still at 9 volts. Will check the charger tonight.

Adrian,
If your 12v battery pack is reading at 9v then it could be that the battery is damaged and may not charge back to 12v. Normal sealed and unsealed lead acid batteries have a discharge voltage of around 11v (not capable of handling a load). Below this level and its time to replace the battery, as it has passed its discharge voltage.
