Are you checking resistance between the posts? Not from post to ground? Go post to post and make sure your scale is set appropriately, or on 'auto'.
I seriously doubt all three coils are bad. Try another meter.
I agree with Will on this. If you're using an auto-ranging digital multimeter, a "1" indicates that the coil is open, and it'* very unlikely for all 3 coil packs to fail that way at the same time. If, however, you're using a manual ranging multimeter, a "1" will be displayed if the resistance is too high for the selected range (e.g. the 200 Ohms range). On a manual ranging multimeter, select the range closest to 10KOhms because the secondaries should be several KOhms.
