check output voltage on charger label most chargers are not regulated so if it says 18 volt output it may put out 24 volts but if its putting out 51 volts it may have a short batteries will get warm but not hot replace charger

Dewalt DE9116 Type 2 c32 and fuse blown . what is the value of c32

A fuse blown ? measure always first the mosfet irf740 if thats not shorted that could be the cause of the defect in case ? or some of the 4 primary bridge diodes replace 1n5408 or by299 presumably c32 its a blue or black high-voltage capacitor .i don,t know for sure but lies in the expectations this is a repair suggestion that could be to find in some popular Dewalt chargers , and do a error research proof allways over a 200w lamp thats in serial with the loader power cable if you make error research to find the part that caused the problem. then you will not blow up parts again if the cause is not find in priority , but a variac and oscilloscope can also be used.

I have a dewalt de9116 charger and when a battery is put in it flashes constantly even a new battery. Is the charger defunct?

I would say tee charger is no good. The only internal component is a circuit board so it is not worth trying to repair it/get spares as it will cost the same as replacing the charger.

Circuit diagram for charger for Black & Decker KC96 cordless drill

You can contact a Dewalt Service Center to see if they have the diagram. Black and Decker is Dewalts lower priced line. A quick search on their website did not reveal anything. They may not have the diagram. As far as I know there are no parts available for the chargers so you may have a hard time locating the diagram. Try giving Dewalt a call.
