Continuity is measured in Ohms (resistance). A low number is better. Yoau want as close to zero as the meter will measure between the negative contact of the blinker socket and the negative battery terminal. Scorpi0 is right, this is typically the same as checking to the frame...... With aluminum frames rather than steel, you need to validate the complete path rather than part way.
Check resistance with power OFF.
Voltage is measured on a 'live' circuit. Power ON.
The meter has to be in DC Volts mode to make this measurement.
Red lead positive, black negative. (That doesn't matter so much, just means you get a plus or minus symbol with your reading, indicating the polarity --- is + really +?) A standard filament bulb doesn't care which way the flow of current goes.... LED lights, do. Black lead on the negative terminal of the battery, when you measure to the negative contact of the socket with the red lead, you should always see zero volts (much less than one Volt).
The positive contact of the blinker socket should also read zero, with power on, until you switch the blinker on. Without the bulb to complete the circuit, the reading should go to a steady ~12 Volts. The number should be very close to the value between the battery terminals.... Within a few tenths of a Volt, likely slightly lower. 12.2, compared to 12.3 at the battery as an example.
If the wires are whole/complete, that's what should be happening. A broken wire, 'opens' the circuit same as a switch does. Where the break occurs will change what readings you get.
Let us know what you measure.
