With hazard switch off, the emergency flasher feed is connected to both the bottom white wire terminal that feeds the rear lights, and the top white wire from the stop light switch feed.
With hazard switch on, the emergency flasher feed connects to the yellow and green terminals for thefront lights, and the bottom white wire terminal that feeds the rear lights, but the top white wire terminal from the stop light switch feed no longer connects to anything, including the bottom white wire terminal that feeds the rear lights.
If I'm understanding this correctly, with the hazard switch off, I should not have continuity between the blue wire terminal (em flasher feed), and the bottom white terminal (feed to rear lights). But I do.
