i was replacing a fuse one day it looked good scratched my head and looked at it. turned out the inside fillament where it makes contact on the ends under the silver cap was broke i had it in my hand for 2 or 3 hours, never gave it a second thought, i was looking at it real close and hell just decided to twist it for some ironic reason ( it came apart) the fuse looked new felt new looked good. until it came apart. put a new one in problem solved. the ole saying is: ( nothing is ever what it seems).
