Fuses are meant to go first... they protect the device in a well designed system.Easy fix : wouldn't mind blowing it again
About the fuse test : saw could use continuity test...For the resistor and LED test, the two sides of the fuse is like two sides of any other component (like resistor) yeah?
"1000V fast acting fuse" : what it means? max of 1000V?
fuse test - yes but a near 0 Ohm resistor so like checking a wire to see if it's broken...
apparently they are rated for 1000V but only 400 or 440 mA whatever it says... we are still talking small current.
