Years ago there was a very popular home computer that had plug in cartaridges. One of which was a MODEM and it tended to be plugged in once and left there for all time.... Well frequently they would fail.. you unplugged. plugged back in and Viola they worked.. WHY?
The answer: There is a virus among us. and it loves low current electrical connections.. and as it grows. it insulates the connection.
When you removed and replaced the fuse you cleaned it.
Suggest some DE-OX-IT two types.. First is the de-0xidizer This will have a number after the name LIke De-Ox-it 5 or De-OX-IT 100 (5 percent and 100 percent strength. I have both in stock) And then there is De-Ox-It Gold.. that is the protectant.
