the way to test is to put a volt meter on there
check them one at a time
IF the ballast is working as it should, one of those should read 8 volt with the key in "run"
the other should read 12 volt with the key in "crank"
then check the two wires going into the ballast, one should have 12 volt in "run" the other 12 volt in "run"
you could technically grab those two wires going into the ballast resistor,twist them together and run a single wire from there to the distributor
