No turn signals or flashers.

Are the silver I think 3 prong flashers different for turn signals and flashers or are they interchangeable?
Thanks to all.


'69 Plymouth Service Manual shows the square two terminal flasher for the hazzards and another for the turn signals.

The hazard fuse covers several circuits and is always hot.
If the dome light works and the stop light works, then there's power to the fuse.
The stop light circuit shares wire D31 from the Fuse to the connector fo the flasher unit. if the stop light works, power is getting that far.

Turn signals only get power when the key is in Run or Accessory. They have no fuse. The flasher serves as circuit breaker.

The places that both connect are the turn switch itself, and the turn switch connector. using a voltmeter you can check for power at the turn switch connector (steering column) and the hazzard connector.
