ive got a problem on my 70 daily driver. i just finished installing my custom dash a few months back when i realized i had no turn signals or hazards. now ive found out ive been driving without brake lights the entire time.

it all started when i think a wire got crossed and a faulty fuse didnt blow. smoke was billowing from the column until i pulled the battery cable. once things were sorted out and the ignition turned on, the flasher would not stop clicking. even though the flasher would click no lights would work.

i was trying to find the problem today, and i noticed that a wire going into or out of the column was completely fried. the wire is the one that attachs to one side of a connector with the other being the white wire coming from the brake light switch.

what is making the flasher click when just the ignition is turned on?
how do i access the wires in the top of the column(close to the wheel)?
i pulled the steering wheel but didnt go any further.

the only wires i cut with the new dash were the ignition, and accessory wires before and after the ignition switch and placed them on toggle switches.

any replies would be helpful... thanks, Tim

Sounds like you may have mis-wired the turn signal switch in the column. It's the brains to the entire signal, brake, emerg. circuit. It makes or breaks the connections to the bulbs, depending on the situation...straight stop, LH turn, RH turn, etc. Get a good diagram and an Ohmmeter and start searching. Fried wire is not a good thing.

(There's a pre-measured amount of smoke installed in every electronic component.. If you let a little smoke out, it'll still work. If you let ALL the smoke out, it's toast

well i let ALL the smoke out, but i actually never touched any of the wires in the column. i was just messing with the wires outside of it. anyway i look at it i need to get inside and replace some wires. i do have a diagram, but it stops after the connector at the bottom of the column and says "to the turn sig switch", which is no help to me. ill get a new one which will help.

thanks, Tim

Sounds like you fried the switch. The white wire going into the turn signal connector, from the brake switch, is the 12 volt power input for the brakes. Something in there is loading down the turn signal input power.
A new switch isn't that badly priced for that car. Since you are in HB, OPG should have stock on a new switch.
If you have the steering wheel off, you should see the lock plate. Round thing with teeth on the outside. That's the next thing to come off.
Disconnect the battery.
Get a compression tool to remove the lock ring. Kragen carries these. You can access the turn signal switch after the plate is off.

Wires to (and from) T/Sig switch are as follows:

Black-Horn
Blue or black with light blue stripe-LF T/Sig
Royal blue-RF T/Sig
Purple-12V Ignition feed for T/Signals
Brown-12V Battery feed for 4 ways
Yellow or black with yellow stripe-LR T/Sig
Green-RR T/Sig
White or white with a black stripe-Stop Light feed, from stop light switch.

Note that when checking 12v ignition and 12v battery feed wires that they go through the flasher. Your test light will be very dim when you find these wires.

The 12v purple feed for the turn signals comes from the flasher. Mine was shorted out inside my column and caused the flasher to click quickly - I believe, quick enough to keep the fuse from blowing.
Check for continuity from the purple on the flasher connector to ground - that'll confirm whether or not it's shorted somewhere. Sounds like it is somewhere in the turn signal switch.

i just replaced all the wires, the connector and the turn signal/hazard switchs up top in the column. it was 37 bucks from opg. now the problem is that only the rear signals and hazards work, but the front still do not. i checked the connection and its fine. could it be the flasher? i got a new flasher but i installed it when the problem was still happening so its probably no good. at first the brake lights wouldnt go off but it was just a stuck switch.any suggestions?

thanks, Tim

Have you checked for power inside the front sockets? Maybe the same ground problem as others on the 70. http://www.chevelles.com/forum/Forum22/HTML/001395.html
