im working on the turn siginals on a 72-the 4 way flashers work, but not the turn sigs.-did the turn sigs. use a diff flasher than 4 ways-theres one plugged in at the fuse box, im guessing thats for the turn sigs., sounds like the flasher is else where when the 4 ways are on, just hard to see under there
the fuse is ok, and im guessing the wiring is since the 4 ways work(this things pretty buggered up)
any ideas

the other flasher is on the right side of the pedal bracket.. about mid way and toward the top.

i found it-the flasher on the fuse block was for hazzard, the other was missing-i replaced it, one flash and it would quite-i had power thru the fuse, but when it went to flash, power disap.-there was some rust on the clips where the fuse goes, insulating the fuse when there was a power draw, so i cleaned it up, now i got blinkers
