Thanks to eveyone who helped - now know the answer.
Borrowed an old transformer type charger (non-travel) and worked OK.
Tested a few volts and found mobile will only charge if charger start volts is between 7 and 9.5
Travel charger starts about 10.5v
Don't have the wherewithall to re-calibrate so a zener in the charger is what it going to get.
