I've got a DC44 in, which either has a charger fault or a dead battery. No power when the trigger is operated. When switched on, the body light flashes slowly, which indicates a flat battery. When battery is placed on charge, there is no light on the charger at all. It should be solid green when charging, off when charged. So does this indicate that the charger is faulty, or the battery has failed?
Charger: I can get a reading of around 24V on the 'max' terminals, but nothing on the 'normal' terminals. This would indicate a faulty charger.
but the problem is that I don't have another charger or battery to do a swap test, and don't want to tell the customer to get a new battery if it's only the charger (which is half the price of a battery). Is it the case that if the 'normal' charger circuit fails, then the battery will not charge?
How can I test the battery output-there are five terminals on it?
Is there any other way to narrow this down please?
