New weird issue

10.45 Volts at key on
12.6 Volts as crank
1.6 Ohm from positive to negative
5.6K Ohms from tower to negative

your coil is toast..

it shouldn't have any connection between the primary and secondary windings...

only ohms should be between the + and -

but!

if you have a spark its probably not your no start issue
