The test that you really need to do is the current draw (in amps) of the coil with the engine running. That reading should be around 3 amps or less. If its higher than that then there is the answer to why your points are not lasting. The condenser is very important and could be the problem. Most people have no means to test a condenser correctly so just fit a new one. You talk about voltage to the points but that is not something that can be tested normally. Only test voltage on the ignition supply to the coil. The 4 volt recommendation coil input is suggested only for 6 volt original Ford bakelite coils . I would suggest that the input voltage on your coil with engine running should be around 7 or 8 volts and not 11 volts that you are reading. Check the coil amps draw running and report back. Dont forget a small amount of high temp lube on the dist cam. Regards, Kevin.
