Question about Makita 2 Bl1830 18v Battery,dc18ra Charger Lxt Fr Drill
Hi ! recently I bought an DC18RA μakita charger 110v to use it in my country
at Europe and bought also a converter from 220v to 110v-1600watt 50-60Hz.
When I put the converter in 220v and after the charger on converter I heard
a sound like bzbzbz and a smell like melting plastic all that keeps above 2 or
3 seconds.After that I saw the 10 A fuse of the converter that has been burn.
Next step is that I was opened the charger and take a closer look inside of it and
what I saw it was the mellting plastic capsule around the varistor ...
Also I measure the Ohm between the power outlet and it gives about 41Ohm.
What I can do from this point and after...?If I m going to replace the varistor and
capacitor it will works?
Thank you in advance!!
...The adapter who I had buy it is incompatible because it uses an electronic circuit to control the thermic
energy depended on it by ohms device you choose to plug ...So I was lucky that day,because the circuits
beyond the varistor damage further than by voltage did not hapened!
I Changed the varistor with a new one from a dead pc power supply and replaced the capacitor with
a new 400volt 220uf and finally it works better than fine ...!!!So if anyone else want
buying a 110volt charger and make it uses with 220volt he can follow 2 ways:
Buy a simple transformer 220volt - 110volt - NO electronic adapter 220volt- 110volt !!!- it will be a
little big and heavy for external use ...OR do the modifications
as I done following the instructions from this very remarkable site !!!

I purchased a new capacitor, varister, fuse and a new plug and carefully soldered in the new parts. I connected a battery and with a long extension lead stood back. As soon as i flicked the switch a tiny puff of smoke and a small pop came from the charger. I have spent hours trying to work out what went wrong. $40 in parts and it destroyed a perfectly new battery. Big disapointment.

See below the submodel of your charger. If the submodel is T than you can't convert it by replacing only the high voltage capasitors. If it S type than the converting should work. The battery itself is ok. Only a little fuse inside is damaged. You can weld a bypass wire on it, else if you can get a new on to replace.
