Graham, to recap: You have swapped the relay, and you know you have four working bulbs.
The relay supplies power to the signal switch. Internal contacts in the switch disconnect the parking light (not supplied by the relay) and connect the pathway to the proper signals side. The load of the bulbs draws a certain amount of current through the relay, which heats up a metal strip. This causes the strip to change shape, breaking the circuit. Current stops flowing, the strip cools and makes the circuit to start the cycle all over again. If you have an issue with all four signals, the problem must lie somewhere upstream of the switch, including the switch itself. When the switch is OFF, you will read voltage at the switch from the relay; the meter makes the connection and allows current to flow. If you have voltage at the switch, try checking JUST continuity across switch contacts. Unplug the wire from the relay; if it is functioning properly you'll just get intermittent voltage, which isn't useful for checks.
