Even if your battery was bad, once running your alternator
would take up the slack. Should read around 13.XV
You would read 12V on the positive side of the coil with the ignition on, even if the resistor is working since no current
will be entering the coil once it's built up a magnetic flux.
Since voltage drop over a resistance is I*R (where R is resistor, I is current). Your voltage drop would be zero.
Once the car is running, and the coil is drawing some current,
say 10amps, any resistances you have in your ignition system
will then have a voltage drop.
I think that those kill switches are 90% of your problem.
If you've got a multimeter disconnect a terminal off your battery
and measure how many ohm's there is across the ballast resistor.
Then measure between the coil positive and battery positive. (with ignition in on position) In theory it should be the same as just the resistor, but if it's a fair bit higher there's your trouble.
voltage drop can occur over old ignition barrel contacts, (kill) switches, dirty contact areas, and bad connections. Eliminte these and you'll probably find your problem solved..
Of course it could be the condensor, points, etc etc...
hope this helps!
