To read Voltage with your multimeter, make sure the mode switch is set to AC or DC VOLTS, that the red/black leads are plugged into the normal + - jacks, and put the leads ACROSS the voltage being measured.
To read Current, make sure that the mode switch is set to AC or DC AMPS, that the red lead is move to the appropriate jack, and put the meter IN SERIES with either wire powering your shaver.
but he only has 6volts to work with! he doesnt have the 3volts to test it! he might kill the razor?
Was the razor running when you measured the current? If not, then maybe you are reading the current that is going to charge the battery built-in to the razor.
I have a transformer that has got 3, 4.5, 6, 7.5, 9, 12 on it but thats from something else so i thought id make one but its prooving harder than i first thought!! lol
Do you want to use next to no parts and spend low $ on it? does it say anything about current or voltage on the back of the shaver??? or the transformer you want to use???
then that motor in the razor is going to need 12volts then not 3!?i think the transformer im trying to use is from a cordless phone i used to have it says 6v 100mA 0.9va on it and the razor says 12v 400mA which i should have read before i plugged it into the mains, cost doesnt really matter its more a case of just being able to do it for my own satisfaction.
where did 3v come from?
well can you use your other transformer and set it to 3volts and see if it works ok? if so read the current draw, and we will take it from there!? hows that sound?i think it does need 3V because there was two 1.5V AA rechargable batteries inside when i took the charging circuit out and if i put and more than 6V to it, it goes too fast ( faster than it did before i killed it) i think the 12V refers to the charging circuit thats all
