The reverse light no warking

I recently tried
the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

Brake light fuses should be in the "fuse box" under the hood.

The signal/ hazard and break light use the run on the same wire The backup light use a different wire and bulb. The tail light use a different wire Check wires and connections

sounds like a bad ground or a break in the wire harness

Yes it could be a relay, but it could also be two isolated problems. The shift will have a switch inside to send a signal either through a relay or directly to the reverse lights. I would suspect the switch. The switch itself may be good but it is not being depressed for some reason. The brake also has a switch. It may be working for the break light but not for lock out of the starter.

check your fuses first.but check the indicators are working first .then check for codes.as it can be break in the wire ,bad hazard switch .or bad indicator switch .or bad relay.need to test each part first.

Reverse light switch is defective, Replace it.

what have you done to inspect the wiring? You got a short somewhere and should inspect
have your ecently changed the tailights or doen siimlar work in the brake light area? Have you tested the brake light switch & wiring for a short? Have you inspected the reverse light switch & wiring for shorts?
As always,. more specific details gets more specific solutions

Your solution is a new combination switch,It also sounds like the hazard are activated and is non operation interfering with the brake light,but either way the solution is a combination swith

"Brake," not "break."

Without knowing the year make and model it is impossible to be specific.

But I can say this: Many cars use the same filament (and therefore the same wire to the socket) for the brake and turn signal. That filament is on steady while your foot is on the brake, and the turn signal is not being used. Turn on the turn signal, and that filament is disconnected from the brake-light system by the T/S switch, but is connected by that switch to the T/S flasher.
