Adambravo Posted July 10, 2011 Share Posted July 10, 2011 Haven't confirmed this, but I believe I've blown a fuse with the Custom Autosound radio I just had installed in my '63 (and, yes, I know that may be indicative of other problems). Here's my question: I stopped by Advanced Auto Parts looking for a 7/8" 7.5A fuse--and I see both SFE and AGW types. What's the difference (seeing as how they look identical)? Not sure what's in there now (although perhaps the wrong 'type' might be making a difference). Thanks in advance...Adam Link to comment Share on other sites More sharing options...
Jim Cannon Posted July 11, 2011 Share Posted July 11, 2011 Both the SFE and AGC are glass fuses with a meltable link within the glass.The SFE fuses all measure 1/4" in diameter. The length is determined by the amperage rating, which varies from 5/8" in length (4 amp.) to 1 7/16" in length (30 amp). The SFE fuse is also designated as "size rejecting" because the size differences are related to the amperage rating and tends to prevent interchanging different amperage ratings.The AGC fuse measures 1 1/4" in length and the diameter is 1/4" for all amperage ratings.
