Driver Side Hazard Flashing When Off 1974 Plymouth Valiant Scamp
Well, it seems at least one of TSSs had a bad hazard switch. I pulled it apart and one of the copper tabs fell out.
I then had to experiment for 45 minute bending and squeezing the two copper tabs so that they made or didn't make contact with the right terminals depending on whether the hazard switch is on or off. What a pain. I ended up squeezing the "hump" part on the larger piece to narrow its point of contact, but I went too far on one and had to go back and flatten it. I've got it working according the multimeter right now. I'll temp connect it in the car and test before I fish it down the column.
