Hi

There is a switch under the brake pedal that presses down when you put your foot on the brake pedal, this iluminates the brake lights, they are plastic and do crak, when they crak the 2 wires can touch and this blows the fuse.

they are tricky to get at as you have to be on your back looking up into the drivers footwell, you should be able to feel it though, easy to do once you get to it, also try some wd40 on the switch if it looks ok.

Regards

Dan

SOURCE: Brake Light Fuse

You have a short in the lighting system. Try removing both brake bulbs and with a new fuse installed.. does it still blow the fuse? If not, then install one bulb at a time and repeat the test.. You probably have a short in or around the bulb socket.. Hope this helps

SOURCE: Radio stops working. Why does the fuse keep

First is that the stock a radio. If it's an aftermarket disconnect any amplifiers, also if there's a power antenna disconnect that sometimes they become jammed. If you still blown fuses disconnect the radio and check to see if it's still blowing fuses. If not get a wiring diagram and find out what other things are on at circuit. It's a simple process of elimination. Good luck with that.

SOURCE: Blowing brake light fuses 1988 E150. Brake switch

To Track down the problem you need to disconnect the Battery and use a Multimeter set to OHMS.

You are grounding somewhere. Start with the Brake switch and see if it is grounded. Then take off the wires to the switch. Check the wires going to the switch and coming from the switch. One side has to be the problem. Check with a parts place like Autozone or Oreillys for a Brake relay in the power box. If the power wire is grounded unplug the Brake relay and see if it drops the connection.

If it is a wire problem, keep tracing the grounded wire until you find a connection you can unplug to make the Ohmmeter drop. Remember the overhead Brake light on the roof. You may have just worked on the Taillights. The bad wire may be grounding in the roof or on the frame.

Once you isolate the bad wire you may want to run a new one.

2004 Ford Ranger 10 amp fuse keeps blowing no brake lights,abs, turn signals?


Fuses blow because there is an overload on the system. If the fuse blows when you step on the brakes then there may be a short in the wiring from the brake light switch to the lights, abs module or turn signal switch. If the fuse blows when you turn the key on then there is likely a short in the wiring to the brake light switch. Basically you will need a wiring schematic to check the wires at the switch and at each of the loads. Also verify that the fuse is supposed to be a 10 amp fuse. Hope this helps

Brack lights wont light up on my 1988 ford ranger we keep blowing fuse and put in new brake switch


If you keep blowing the brake fuse than you have a short in the system. Unplug the brake switch. Install a new fuse. If it did not blow than the problem is after the brake switch. Next unplug the turn signal switch, then plug the stop light switch back in and press the brake pedal. Did the fuse blow. If not than the wiring is good in between the two switches. With the turn signal switch disconnected use a jumper wire in between the light green wire (power from the brake switch) and the orange with light blue wire (power to the right brake lamp). If the fuse blows than there is a short in the right side brake circuit between the plug in and the rear socket assembly. If the fuse does not blow than jump from the light green wire to the Light green with orange wire (power to the left brake lamp). If the fuse blows than the problem is in the left hand brake wiring circuit.

Start by replacing your brake light bulbs. If it still blows the fuse, them your brake pedal switch. If it still happens then you have a shot circuit in your wiring between your fuse panel and your brake lights.
