If Phillip has the large connector on the coil end of that wire I think 
it has 5k in it, so this sounds fine. Your rotor should have another 
5k in it, too.

In general, these have only failed when the resistance goes to 
infinity. It is a wire-wound resistor and it only fails open. Even then 
the spark will simply jump the break for a long time.

BTW, if you are lucky enough to still have the OE SP wire set with 
the nice screw-on right angle connectors at the distributor end, 
DON'T throw them away; just replace the bad parts. Did you know 
that you can just cut new wire to go in there? Besides, the late 
wires, with copper wire conductors seldom fails anyway.
