68 Fuse Box issues

Anyone had issues with just one or two of their circuits of the Fuse Box. My bottom right 2 circuits (switched) have power going in but not out. Fuses have been tested and are good.

New wiring harness for Engine side, using existing for cabin side. Tested and power going in and power coming from the ignition

Before I pulled the fuse block out and looked behind it I was curious to know if anyone else had a similar issues.

thanks in advance

Don't take everything apart until you try the basics.

Take some fine emery cloth or very find sand paper and clean away any oxidation and corrosion on the inside of the fuse block clips. The curved areas that grasp the end barrels of the fuse need a good clean contact or you typically get what you are experiencing.

Re: 68 Fuse Box issues

Are the contacts where the fuses go rusty? Mine are and cause problems all the time. I once years back used a ball tip carbide bit and cleaned it up real good. Isn't 100% but for the most part now it works.

Afterwards a good finish up and PM that I do is coating the contact area with WD-40.

Re: 68 Fuse Box issues

Thanks for all of the great advice. I am going to tackle it this afternoon and will post what the problem was.

Regarding cleaning the contacts, I thought they were clean but now thinking about it I did not inspect. I popped the fuses in and out a couple of times as I tested them with my Ohm meter to make sure that they were good.....eyes not being what they use to be....
