I keep blowing the fuse for tail lights the instant I touch brake pedal in my 67 Chevelle. I had found wires that were twisted together and taped, so cut these and used butt connectors to reattach. Still same problem. Also the hazard lights keep blowing the fuse. Where do I start?

I had a problem similar in my 69 chevelle...there was damage to the harness that goes back along floor, under the back seat to the trunk. The rear seat had worn the wire and it was shorting out off/on...very frustrating as it was intermittant for me.

Hope that this helps, good luck

PS I would loose tail lights and also the four ways would not fash, then the fuse would go.

I think that makes sense.If the hazards are tied in with brake lights, that is why they keep going also? Can I bypass the flat wire under carpet to check this, and if so exactly how would I go about this? Thanks for all your help, Steve

Another posibility is the plug in connector for the rear wiring harness. On my car, the plug in connector just fell apart (age, I guess). This left non-insulated wires just laying on the floor. It did not short out, but there was no power to the rear lights and the fuel gauge did not work (stuck on "full"). The plug in connector on my car (a convertible, if that matters) is in a hard to get to spot behind the rear seat back. I could not see it but found it by feeling around.
