Thanks for all the help Guys. I guess I'll start from the back and work my way forward. I'll let you know what I come up with. |

Luigi,
I had a problem on my car after replacing a brake light bulb. It would blow the fuse as soon as I put my foot on the brake pedal.
It turned out to be a bulb with a dead short across it! � To prove it was a dead short I broke the glass and removed the filament � checked with the Avo and we still had continuity!!
Can you put an ammeter in line somewhere to see what current the bulbs are pulling?
A single 21-watt stoplight should draw 1.75 amps @ 12 volts � if there are 4 lamps (someone please confirm!!) you should read about 7 amps.
If your reading is normal, you could put a packing piece in-between the switch and the brake pedal so that the brake lights stays on. Then you could go round the car gently �wiggling� the wiring loom etc.. . You would need someone else to keep an eye on the meter for fluctuations.
Hope this helps
Paul

I agree with Jeff. There is a short in the line. |

Sounds like a power wire either pinched or chaffed and making intermittent ground contact. It seems that driving around creates vibrations and motions resulting in a shorted circuit. I too have had my share of wiring troubles with my TR. I've found most problems by simply tracing the wires from the lights back up to the fuse panel. It may seem odd, but also check the bulbs and sockets for problems too. Keep us posted on your developments. |

The fuse for my brake lights keeps blowing. The problem is its to random to find. Once I change the fuse I can apply the brakes and keep them on for 10 - 15 min. and there is no problem. I can drive around for an hour or two sometimes only a couple of minutes then bang a light comes on the dashboard for my brakes. Go check the fuse and its blown. Any suggestion would help. Don't know where to start. In a previous thread I had this problem where I had no brake lights at all and the fuse was good. With a lot of digging I found two inline fuses spliced on the feed wires one for each side of the car. I put two 15amp fuses in them and a 15amp fuse in the main board as per the manual. This worked for awhile so I thought the problem was solved, and I had bake lights again. But know the fuse keeps blowing. |
