I had the exact same problem. I ordered the ZNR V10 241U part from Dija Key. They are around 36 cents if you buy 10 of them. I cut the old one out and soldered the new one in. I changed the fuse over to an automotive one so the fuse is easier to obtain. I plugged it in and charger works fine.
What happens is a voltage spike either low or high gets recieved by the charger. The fuse appears to be slow blowing and does not stop the spike in time. The spike is stopped by the varactor surge supresser. In doing so, it saves the circuit board so all you have to replace is the fuse and the surge surprsser.

So if anyone has broken makita chargers they don't want to fix I will take them.
However, on ebay one of these chargers can be bought for around 25 bucks. farr better than going to Home Depo and spending $100.00.

Code on the VDR is
ZNR
V10241U
G01
Dont think that will really help though
I've got exactly the same problem! Did you got any answer on this. I've got mine from the internet, so no shop to return too....
Regards
The part that's blow up is a Panasonic 110v "Transient/Surge Absorbers" (basically stops the charger getting blown up by voltage spikes on its powersupply). Look up ZNR V10 241U on google and you'll find the Panasonic spec sheet.
If it's blown (and you're running your charger on 110v) then you've probably fried something much more expensive inside too. Unless you feel like replacing the MOSFET (2SK3528), its time for a new charger. Sorry.
