Bingo: it's clock, amperage (typically .25 amps) and ohms. Depending on the solenoid, as brother Jim already said, it will be between 20 to 60 ohms. I've had many solenoids show good until they heat-up and fail. Bottom line, is a short is when the measured resistance is below 20 ohms for a single solenoid. Above 60 ohms will indicate a open when measuring the field wiring.
