Dead giveaway for fuse box problems

Yes, those OE-type fuse clips are NLA and are now as scarce as hen's teeth. Never did find an exact replacement from any of the electronics suppliers, from McMaster-Carr or similar sites. I have a few NOS ones that I have hidden away so I won't use them unless really I need to, and always try to refurbish the old ones instead.

Of course you can easily remove the fuse clips from the fuse box in order to clean them. If the fuse box has a burned out spot, you'll have to either get a new one or glue the fuse clip in with plastic epoxy.

I've had good luck cleaning the old fuse clips with acetone, filing off any rust or corrosion and installing the fuse with a tiny dab of silver conducting paste on its ends. Besides being a super good conductor, the silver conducting paste also greatly increases the contact area between the fuse and the clip and assures a low-resistance connection.
