Mike: Doesn't need a common (or ground). No chassis (case) ground needed either. The 3rd prong on my GMC flasher is output to the dashboard turn signal indicator. Only one dash lamp on the GMC, flashes for either direction. See lower right corner of schematic here http://chevy.oldcarmanualproject.com/gmc/5559mm/5559mm302.html Bill ________________________________ From: old-chevy-truck@yahoogroups.com [mailto:old-chevy-tr...@yahoogroups.com] On Behalf Of Mike Burns Sent: Thursday, October 28, 2010 8:32 AM To: old-chevy-truck@yahoogroups.com Subject: RE: [old-chevy-truck] Re: turn signal flasher
I guess that I don't understand where the source voltage gets into the flasher. Since there are only 2 prongs, does that mean that the can itself is being used as the 3rd prong common?

They have a bi metallic strip that heats and cools to flash.
