both flashers are the same, try to swap the haz for the turn flasher
not owning a multimeter is no excuse; harbor fright gives them away and sears has them for $10
i see you a canuck, how boat going to canadian tire and see what they have for cheap?
cheap and free multimeters work fine for checking continuity and voltage
i owned a fluke for many years until i let the smoke out of it
now all i use is the freebies from harbor fright, i have 3 of them
