Can’t find wiring diagram for 95 Mack need brake lights keeps blowing fuses


Recommended Posts

Check for shorted wires / damaged sockets or bulbs in the brake lights themselves. Easy way to do it is pull a bulb and see if the fuse blows, if it does go to the next light and do the same.  When the fuse stops blowing it will be the last unit that has the issues. No issues found look to the directional switch as the brake light circut runs through it.

Directional light switch mounted on your steering column, you pull its lever when activate turning lights.

Brake light switch is too probably mounted on the engine side of the firewall if your 95 Mack is model RD. Relatively easy to find since that's a kind of sensor mounted on the firewall an air line comes to and two wires attached to terminals with small nuts atop of. The switch is operated by air pressure when you apply the brakes. Sorry I have no idea on where such thing was located on CH, CL, MR etc since Mack produced many different trucks in 95. But i'm sure it operates the same way and its location could be found in the same area.
