no power to switched fuses

Hey y'all,

I'm new to the forum, but i have a problem with my 67 el camino's fuse box. I have power to the constant 12v fuses but nothing to the switched fuses with the key on. The car will start and run with 12 volts to the hei and there is 12v to bothe sides of the horn relay. Any ideas?

Re: no power to switched fuses

Do you have a test light or a voltmeter to check for power?

What is the condition of the fuse box? These fuse boxes are notorious for getting corrosion build up on the clips that hold the fuses. Even if the fuse is good and tight in the clips, sometimes you won't get any current to pass because there is such a poor electrical connection between the ends of the fuse and the clips in the box.

Also, plug to ingition swich looses connetion when wires get hot. Use the test light to see if the power is comming through the ignition switch.

Brown wire leaving ignition swich going to fuse box (12 gauge) should have 12v when key is in run position.
