Check each battery voltage before and after charging.If voltage do not increase over the voltage of the battery, the charger is defective.

if baatery had been changed before fail appear, check polarity of each one, do not trust to the polarity color or label, sometimes mistakes had been maded during the manufacturing,

Check selector Charger, operation. Do you have voltage after switchs and reles conmute?

Check voltage in off and after turn it on,a suddenly drop mean a bad module

Best regards

If batteries measured voltage without plugging in the cord measured on the charger board TP9 and 10 is below 109 you are having a problem with either the charger board or the batteries need replacemnet
