Hello and WELCOME. As for the flasher, I think a Georgetown is on a Ford F53 chassis. You can go here:

On the left side of the page, look under owner manuals. Then select year, etc. Hope it helps.
One other thing to always check, make sure the 4 way flashers are working. Sometimes if they don't work, the switch will get turned on, and this will cause the regular flashers not to work.
