Constant spark from coil

By disconnected I mean I took off coil wire to distributor and placed tip near metal to test for spark. Then it proceeded to produce an endless stream of spark when cranking. Too much spark.

Should have been more clear.
The coil fires 8 times every 2 engine revolutions. If the engine cranks fairly fast of course it will have a fairly constant spark output. Plug the coil wire back in and chec for spark at on cylinder. You will get one spark every 2 revolutions.
