brake lights

[jt1200r]

i have no brake, turn signal or hazard lights. the running lights and front turn signals work. any ideas where to look ? its a 87 r10 step side. Thanks

Pull out the rear lens housing(s) and check the ground wire(s). They usually get rusted/corroded up and make the back lights dead.

if has a trailer harness on it check that also, a lot of time they were butchered when put in and will cause major headaches

if all that fails check fuses.

 

[jt1200r]

the fuses are good. no trailer harness. ill check the ground tomorrow. thanks

should have also said the running lites and back up lites work

Might sound a bit dumb, but check the bulbs. Maybe the brighter filaments have burned out.

Turn signal switch ?

 

[jt1200r]

the bulbs are good.the front and dash signals work

Could be a break in a wire along the way towards the back. If you have a tester, turn on the hazard lights and check the socket for signal. If none step back to the wires about a foot upstream and check again. (Tester might have a probe you can use to pierce the wire enough to check it.)

ill give that a try

Isn't there a plug in the harness near the cab that runs to the rear lights? I'd check that too with a test light.
