Testing for Continuity
Set up your multimeter to test for continuity as shown in
test points, and read the display.

test, disconnect the circuit power and discharge all high-voltage capacitors
before testing for continuity.
Continuity is the presence of a complete path for current flow. The continuity

test features a beeper that sounds as long as a circuit is complete, if normal
open is selected (or broken, if normal closed is selected). The audible alert
allows you to perform quick continuity tests without having to watch the display.
In continuity, a short means a measured value is less that the threshold resistance
