Hi I recently had to replace the brake light switch on my 95 mustang 3.8 and didnt unhook the battery. while doing it i arced the hot wire and after i was done the brake lights and turn signals didnt work. I know they are both on the same fuse so i checked that and didnt blow the fuse. I replaced it just to make sure. after that I took a test light to the fust box and im not getting any power to that fuse but all the other ones are getting power. does anyone have any ideas?

 

would a faulty flasher unit cause this ?

 

Did you check the fuses under the hood AND under the dash????

 

Your lucky you did not kill yourself, its a good idea to disconnect the batt anytime your doing anything with ELE on your car. Not trying to be a jerk, just trying to help. I have seen people get hit by high voltage and by high amps, both not good.

Do you have a voltmeter or are you using a cheap fuse checker?

 

High voltage on a car? A car electrical system can defiantly put out enough Amps to hurt or kill, but the voltage isn't what you have to worry about, and if you are working on something that is fused with a 15 amp fuse, you have nothing to worry about. 12 Volts at 15 Amps will hurt some, but isn't dangerous.

 

I know that cars don't run high voltage, I have seen high voltage hit people is what I was saying. I know that its amps that kill you, and they will if they hit you just right. And stuff happens and while you are right that a fuse on the line will make it a lot safer, it doesn't hurt to be 100% safer by not working with "hot" lines.

 

i think you went overboard by saying he could have killed himself working on his car electrical, but i get what your saying.. im an electrician btw too

 

thanks for the ideas guys i found the problem and i just need to replace a fuse under the hood didnt even think of them. but regardless for now on the batter will disconnected befor i do anyhing electrical.
