rear pillar brake lights not working but side lights are and bumper lights all working, Any ideas

Forum: 

All lights at rear of fourtrak f75 are working except pillar brake lights? Any ideas?

Does it have any?

Start by checking if it was fitted with pillar light units.

Yes it does

Hi
Thanks for reply
Yes it does have the pillar lights but for some reason the side lights on these but not brake lights??

corrosive plug

these suffer from corrosive cables/plugs on the harness behind the light unit, easy fix witb some wire cutters n joiners etc, check all fuses first though next to the throttle.

Full of ideas but no time to do them!!

Begin with the obvious, check

Begin with the obvious, check for voltage at the brake lights, you will need a tester, and an assistant holding the brake pedal down with the ignition on.

If you have voltage, move to the brake light switch, check incoming voltage, operate the brake and check for output voltage. If you have input voltage at the switch and no output it is the switch which is faulty.

If you have output from the switch that it is a wiring fault between the switch and lights, check this, noting the connectors. These corrode, as do the bulb holders, so check especially for wiring breaks.

If you have no power going to the switch then it is either the fuse or switch feed wiring.

As a footnote, have you checked the obvious, are both bulbs working as sometimes one blowing causes a surge which will blow the other.
