Same dealio over here on my 67... haven't checked the motor on it, but I know it has about 4 wires cut... the signals work in a normal car fashion... does that mean they just cut those wires and it's like that? or they added something aftermarket?
well the deal with mine is...that somebody had cut the wires under the steering column and i spliced all of those back together. I turn the key over and notice that the turn signal light on the dash is on..but not flashing. The power wire to the motor (sequencer) was disconnected...so i hook it up and the motor now spins, not no flashing dash light or signals. Oh well..tonight was the first night to attempt anything, I guess I will try again tomorrow after school.
Well, I dissected my sequencer motor/switch box today. The three wires inside were removed and spliced into one.. and the power source inside was removed and put to a standard flasher unit with the other wires that were spliced together.
So anyway, the motor insides look a little like CRAP and the transmission thingy seems to go one direction for the most part. I think I'll hit the local electronics supply (not radio shack) and see if I can find another motor...
PS ~ I just added a pic of the wires on mine, and the dissected motor/sequencer unit to the Misc Info page on my site.
