Any voltmeter is magnitudes higher, as I said, 10,000,000 is common. Not that that has anything to do with anything - you claimed putting a voltmeter across the (bad) fuse would kill the LED. It won't. You only know enough about electronics to be dangerous, as you prove time and time again in your unique form of gibberish.
5 MILLI amps of bleed can cause a 5-volt potential exist in a switched buss, try it with reality instead of a calculator and sharp pencil.

A simple voltmeter voltage check across that fuse should kill the LED 5-volts potential is more than enough to fire a 3mm LED with resistor.
