Help Electrical

[Rigo]

I need some help finding out why my brake light don't turn on when I brake.
I've checked the fuses I can see, but might be others.
I've checked the light bulbs also.
I can not find the wires that go from front of motorhome brake to the rear lights, there are many wires that change colors every so many feet.

Are you referring to the coach lights, or your toad? What year/coach manufacturer/frame manufacturer do you have?

Somewhere on your vehicle there will be a switch to activate the brake lights when the brake pedal is depressed. If your fuses are ok, I would start by checking the switch. On my Ford E450, the switch is located under the hood on the brake master cylinder. Not sure of other vehicles. What type of chassis do you have?

Are brake and turn same or are brake red and turn amber?

If same try turn signal as it is same wire fuse and bulb.

If same brake light switch provides power to bulbs via turn signal switch.

Check for loose connection.

plz go to your profile page and update your signature block to include info about your RV.
my brake light switch is located under the dash. there is a plunger that rides on the brake pedal arm. my sw has 2 parts. the other part releases the cruise control when the brake pedal is pushed.

My system is wired so as the brake lights come on when I press the RV brake pedal, when my car brake system is not installed.
However, since I use a diode pack, when my brake system is installed, brake pedal is push, brakes lights will come on. So, it all depends on how you wire your system.

As an extra, my third brake light ONLY comes on when the car brake pedal is depress.
