Hello.
I bought a used 4-port Makita battery charger (Chinese copy I think)
Anyway only 3 ports seemed to be working albeit with some audible electrical harmonics while charging the batteries.
The non-working port would quickly change to green led from red, even though battery was only half-full.
So I opened up the charger, sprayed electrical contact cleaner on the circuit board and waited for the cleaner to evaporate or so I thought. When I plugged the charger in, bang! It blew the little glass fuse and I inadvertently took out a second port. 1 circuit board charges 2 ports.
Any gifted repairers out there??
