Fuses...older vs newer? type

[Pete Munroe]

All,

Blew the parking light fuse (#6) while messing with the front turn signals. Replaced with a spare AGC 15amp fuse.

Went to buy more. All I saw were "FAST BLOW" (obvious with the thin element) and "SLO-BLOW" (a heavier but TWISTED element).

OK what ever happened to just a "STANDARD" all purpose fuse? Is the older "STANDARD" style...lead strip with a notch in the middle...now replaced by the SLO-BLOW with the twisted element...?

Have used a magnifying glass looking at the old fuse that blew but can not find any part number/description beyond, at one end, "32V" a "logo" of some sort, and "SA" in a circle)...the other end has brand, style and amp rating "BUSS AGC 15A".

So what I call the OLD type "standard" heat range fuse (with the lead strip) now the equivalent of the currently marketed "SLO-BLO" with the twisted element...?

Think the NAPA store still has what I call the "older type" but the other chains very few if any. On line you can't really tell what you are looking at as the photo could be of anything.

Thanks, Pete
