you can ohm it out from primary to secondary. I usually do a good close up inspection of it . Look for cracks in rubber or sooty looking marks usually on back side for shorting to ground. If you suspect a bad ignition coil, or coil pack , replace it at Autozone.

A 1997 Jeep Grand Cherokee has one ignition coil.
Here is a photo of the ignition coil. It is in the engine compartment against the fire wall. if you find the distributor with 4 wires going to the spark plugs, follow the distributor center wire which plugs into the ignition coil. A new coil is about $150. Good Luck. Sorry, the photo didn't work. Search at "http://www.gprparts.com/OEMParts/vw.asp" for a 1997 Jetta igition coil to see the photo
At 6500-11500 ohms, the resistance on the ignition coil is okay. If the resistance exceeds 11500 or below 6500, the coil requires replacement.
