Pertronix Ignitor 111 troubleshooting

Checked cap, rotor etc. Everything is like new. Onle have 1100 miles on setup. Good ground, 12 v when cranking, no pluse or blinking when cranking.
Doesn't show any rpm when cranking. Check my 1972 Satellite, doesn't show RPM when cranking.

Change the coil with a good use one. Nothing.
