Bosch 18v driver/drill charger won't charge
THRE ARE MANY POSIBILITIES.HERE THEY ARE:
1. Check your charger's wire.Most of the wire s are always damage in the root of plug & to the opposite side.
2.Check the fuse.
3.Check the Rectifier Diodes.How many Diodes do your charger has?most of the chargers are only one,sometimes 4(a bridge type,& somtimes only one but 4 legs( it is also called a bridge type)
to test a 2 legs diode is just simply get a multi tester and adjust or set it in X1.,then look for the white band(mark) of diode,if you can see that mark,remember that it is the positive side.what will you do is put the red pin of the tester to the positve side of the diode,& the black pin of the tester to the negative side of the diode.If if the neddle of the diode will move,then you must reverse the pin of the tester,the red pin now will be put in the negative side of the diode and the black pin of the tester now will be put on the positive side( to the side with white mark or band).
now,if the neddle of the tester WILL MOVE after doing this reverse test: im sure that your diode is dead and needs to be replaced
Note:even most of the time you can do testing diodes attached on the board..,it is strongly recomended to detach one leg of the diode to the PCB or circuit befor doing the test.
Hi, Dennis I would really love to help you with your bike question but due to the magnitude of yesterday's solar flare the batteries in my crystal ball are dead and my mental telepathy headset circuitry was melted. I need the year, make, and model of your motorcycle please click on " Request More Info" directly above and provide this information in the box that will open and then click on the green send box in the bottom right-hand corner after it posts I will receive an "ALERT" icon that will allow me to respond to your information. Good luck and have a wonderful day.
