Stumbled across this dandy little device quite by accident: http://www.ebay.com/itm/251373428739...84.m1439.l2649
It'll do all blade-style fuses---its adjustable for chrissakes.
Autozone sells them in-store naturally by themselves or in little kits with a small selection of replacement fuses.
Anyone who's ever fumbled around with a test light looking for a good ground and trying to NOT create sparks when testing the cabin fuseblock will immediately see the wisdom in this thing.
If this is old news apologies but its still cool!
