Thanks for the clarification regarding the CAS used in Hondas. I had
the variable relucntance crank sensor in mind. Testing these reliable hall
effect sensors is usually done by back-probe the 2 output 5v signals. The
switching should be a clean 5v on then 0.0v off.

Reason for asking is that if you're getting a signal from the ECU to the
igniter on the new distributor then I would assume a bad CAS or the
like. Since CAS are known to be reliable.
