With the points open you should read battery voltage on both small terminals. With the points close you should still see some voltage but it should be lower unless the points are bad or need to be cleaned
 
I pretty much agree with Old. With points OPEN if all else is okay ??? there would be battery voltage on BOTH sides of coil. With points CLOSED there should be voltage on coils input BUT NEAR ZERO VOLTS ON OUTPUT (to distributor). If the points are badly burned or pitted or oxide coated or not fully closed that's when you would read some voltage even when closed THATS BAD so check clean and gap the points.
