How do you check power to distrubitor?

To check power to the distributor, first ensure the ignition is turned on, then use a multimeter to measure voltage at the distributor's power terminal. Connect the multimeter's positive lead to the terminal and the negative lead to a ground point. A reading of around 12 volts indicates that power is reaching the distributor. If there's no voltage, check the ignition coil, wiring, and fuses for issues.
