Is the dist off the engine? Connect the switchbox to the dist. Connect the battery voltage to the switchbox, so the dist and switchbox are connected just as they would be on the engine, Put spark tester on one of the spark plug wires, then with the key turned on grab the shaft on top of the dist and spin the dist, the spark tester should fire.You only need to spin by hand you don't have to spin it fast it is a battery operated system.Let me know how you make out.
