SM2GXN Posted February 19, 2006 Report Share Posted February 19, 2006 Hi!I'm about to repair a battery charger made by Makita model DC1411 with blown mains fuse.Found a shorted diode which seem to be part of the snubber network.Marking on this diode hard to see think it is H8V.93 but not sure, there is another diode on the secondary side having similar marking H6V99Anyone seen any of those or know how to get data on them?

stig Posted May 3, 2006 Report Share Posted May 3, 2006 Hi, i'm busy repairing the exact same model, the diode is obviously a weak point, unfortunatley i'm also having trouble identifying it. did you manage to find any specs for it..stig Quote Link to comment Share on other sites More sharing options...
SM2GXN Posted May 3, 2006 Author Report Share Posted May 3, 2006 Hi Stig and welcome to this forum!No haven't found any sub yet the project has been on ice for a while ;D there is also one more blown component and that is the thermal fuse which is open.Good that someone reminded me :) I'll start up again and if I find any sub for this diode I'll let you know.

ante Posted May 4, 2006 Report Share Posted May 4, 2006 This might be nothing but; if you remove the H6V99 and measure it will it come out smelling like a zener? Perhaps 6.9Volts or so? Quote Link to comment Share on other sites More sharing options...
SM2GXN Posted May 5, 2006 Author Report Share Posted May 5, 2006 That's possible but the H8V.93 seems to be part of the snubber so probably not a zener, I'll have to check the circuit again but not tonight it's friday and it's way to hot and I'm thirsty too ;D Quote Link to comment Share on other sites More sharing options...
