Fuse problem in 69
#2
Melting Slicks
I'd start by checking the stop/hazzard light sockets for corrosion or a bulb that isn't properly inserted, something that may be causing a short resulting in the blown fuse.

Find the 'short' in the fuse holder or wiring for that circuit.

If I remember right the hazard relay is under the passenger side dash near the passenger door. It's real easy to unclip it and check it out. My 69 was nearly burned to the ground because of this. My dad had an Einstein moment (about 25 years ago) and inserted a piece of metal (a freaking Wrigley's gum wrapper) in the fuse block of what is currently MY 69 to stop this very same problem. He was bringing in groceries and when he went back to get the second bag, he saw the smoke coming out under the dash and quickly yanked the wrapper out.
After I bought a new harness for the interior, I saw the damage. All the wires going to that side of the car were all melted together and shorted.
P.S. - My dad reads the forum and he is gonna kill me if he sees this.

Hey bud,
First, diagnose what is happening,does the fuse blow when you put a new one in, right away, or does it happen when you turn on the ignition, or when you press on the brake pedal. Have you been working on the car before this started? Here's what I would do to narrow it down, assuming it happens when brakes are applied. Start at the furthest point away from your problem, pull all the bulbs, step on the pedal,does it still blow? Yes, leave them out, remove the hazard relay, step on the pedal, still blowing? Yes, now your really down to two possible problems, the brake switch itself(which also has a resistor that goes bad) and the turn signal ring.
If it blows with the ignition off and stepping on the brake pedal, it's the switch.
If it blows when the ignition is on and you step on brake pedal, turn ring finally broke.
I'm sure other members have tricks to make this easier, I'm no expert, but the method works for me,good luck....

Thank All,
The fuse blow up, when I put the fuse it in the fuse box (no ignition, no brake pedal)
I've removed blobs in stop and turnlight, hazard relay and the stop pedal switch.
And still it blow up my fuse !
OBS OBS !!!!!!
I've found a part of my problem, please see picture.
It is the brown wire, it is markt "K" on the plastic connection box.
It is the brown wire the blow up my fuses.
When I disconnect it, I have no problem !

Your problem is in the wiring somewhere [if you have removed all of the components and it still blows when new fuse is installed]. Check your wiring, per wiring schematic, between the fuse block and the first removed component in your circuit. Chances are there is an area of insulation worn through on some power wire and is grounded out. You may even see some lightly burned area there. Your problem could also be in the fuse block, itself. You can also remove the battery cables [both of them] and use an ohmmeter to find the short in the circuit.
