Re: No power for radio hvac or vic
Where all the fuses of the same amperage? A too low amperage fuse could melt imediately when the power was switched on. An other possibility is that there is a short somewhere, melting the fuse when inserted. Or you just had bad luck with the fuses you bought.
There could eventually be something wrong with the fuse holder itself; a loose connection inside the junction block or the blades, which should make the electrical contact with the fuse, too wide open.
