im having problems with a cordless makita drill battery charger and was wondering if anyone can help me. when i put a battery pack into the charger it doesnt start charging. ive checked the transformer it checks out ok. i checked out the start button , reset button , it seems like the reset button isnt working , is there a way to check all these out maybe im doing it wrong. this charger is for 12 volt batteries. any help at all would be greatly appreciated . dont wanna have to go spend money on a charger unless i have to
