  • No Brake lights and no dash lights.

    I don't usually drive the TR6 at night but tonight I realized that my rear lights and dash lights are not working.

    I tried a search and it looks like these are on the same fuse (will not be able to check until tomorrow). Am I on the right track or is there something else I should be looking for?

    They are on the same fuse..red wires exiting the fuse.

      Ok, The fuse was indeed blown.

      I replaced the fuse, turned the lights on.... the tail lights and dash lights came on for a second and then I blew the fuse again.

      Now what?

        Brake lights or taillights? Brake lights are powered by a different fuse than the taillights. If the fuse for the taillights is blown then you would also lose the front marker lights. If your front lights work then your problem is downstream of the fuse.

          Tail lights, front markers and dash lights are all out. My TR6 is a 1976.

            The topic title says no brake lights (green fuse). The body of the message says no rear lights (red fuse). Is it both?

            Do you have front parking and marker lights? Are the fuel and Temp gauges, turn signals and heater fan working?

              I guess the first thing I would do is open the trunk and look for anything obvious. Are the wires still connected to the tail lights? Are you carrying a bowling ball around back there? If nothing looks am miss then I would disconnect the multi pin connector taking power to the rear lights. It's located (or should be) behind the left front carpeted trim panel. (Right next to your shin if you were seated in the car). Put another fuse in and turn on the lights if the fuse blows again your problem is with the dash lights. I suspect however that the fuse will not blow and you will be left with finding a short in the rear part of the harness. The tail lights are notorious for poor grounding but before you tear the car apart it helps to eliminate as many things as possible.
              Good luck

                Maybe check that the boot light lead is not disconnected/grounding out, or the license plate lamp.

                I can't recall if there are maybe two red connections at the fuse box, one feeding front and the other feeding dash and rear?

                Edit: Looking at me fuse box, looks like they are tied together on the same spade. Push come to shove you could separate them to help isolate the problem at lease from front to everything else.

                You might look at that boot lamp first...

                  I found the multi-pin connector on the driver side firewall but was unable to contort my body to get it apart.

                  I will take it to my mechanic and have him figure it out

                    Just an update.

                    The wiring to the rear license plate bulbs frayed by contact to the body. This caused the short. It took them a long time to figure this out.

                      Same thing happened to me years ago. I didn't take it to a shop and it took me a while to figure out it was the license plate light lens had broken into 2 pieces, causing a short.

                      I had the whole dash dismantled before I finally found the problem, no 6-Pack forums or even internet in those days. At least I learned how to take the dash apart!

                      Thanks for updating your thread.

                          I ran across your post. I am having a similar issue. Look at my post "wiring Help" and see if matches your issue. My lic plate lamp wires are not connected to anything, so I assume it could be the cause of my short. Thanks
