coil resistance

I have a 1984 mustang 302 TFI CFI . automatic I have no spark so I went through the tests in Manual first test was coil it states that you should have 0.4-1.0 ohm on primary and between 8,500-11,000 on secondary my coil showed bad secondary test bough new one from NAPA and tested 2 different ones at the counter and I got 0.7 on primary and and with meter set at 200k it reads for secondary 0.79 and on 20K range it reads 7.95 ??is this any good?

Make sure your battery is good on your volt-ohmeter. Be sure and zero your meter to account for lead resistance. Then measure. The 7.95 is most likely 7.95k ohms on the 20k range. Good Luck!
