Engine Speed Measurement
This connection is dependent on your ignition system. You should
read these instructions carefully and make certain you have identified
the correct connection point before you begin.
To measure engine speed you must make the correct connections be-
tween the ST700 Dash Display System and the vehicle ignition system.
Contact Stack for advice if you have a complicated ignition system.
If you cannot use any of these engine speed connections, you may use
the optional Stack ST697 HT pick-up to get a signal from an ignition
lead.
