It's the same basic procedure but with a change in the connection points.
As you know, when checking for power, you clip the lead from your test light (or black multimeter probe) to a known good ground. Then touch the test light probe (or red multimeter probe) to the point in the circuit where you're testing for power.
To check a ground, you clip the lead from your test light (or red multimeter probe) to a known power source (could be the positive battery terminal or a terminal in the fuse box that you have already verified to have power). Then touch the test light probe (or black multimeter probe) to the point in the circuit where you're testing for ground. The test light will light up (or multimeter indicate system/battery voltage) if the point you're testing has a good ground.
