The  unmarked terminals are for connecting a small 
light.  The light used should not exceed 100mA of 
current draw. A 12 volt LED, available from Radio 
Shack

®

, works well.   This light is a remote of the 

light on the unit.  The light may be useful to help 
determine the best settings during initial testing, 
then removed.  The details of this will be covered 
later in this manual. 
 
It is recommended to check the static timing before 
and after the installation.  The static timing should 
not vary by more than a degree or so.  If the timing 
does change then there may be a problem, and the 
unit should be disconnected. 
 
The design of the system allows for it to be 
connected or disconnected with the engine running 
if needed. 
 

However this is not recommended, as this could 
result in severe electrical shock if the magneto is 
running. 

 
If a problem is suspected then the unit can simply be 
disconnected from the kill wire leaving the engine in 
original form.  Disconnecting the power supply 
should also deactivate the system.
