" About 3.5 vdc "
That means you have battery voltage to the points & they are closed.
" The condenser had a good ohm resistance reading."
And that doesn't tell you anything.
" The coil on the other hand was outside of the normal ohm reading."
And that would be what?
You're not burning up coils in 30 seconds.
Chances are this coil & the other one were fine.....so do tell us what the "normal" reading is supposed to be & how you are checking coil resistance.
" I replaced the coil with a new aftermarket from ebay"
And that could easily be the problem. Get your parts here at YT or from Just8N's.
