Anchor Screws 

Controls 

Control Wiring

 – Control leads are connected to the ignition via a Control Plug that 

captures each lead with a screw cage mechanism.  The plug is then attached to the 
ignition and secured with anchor screws on either side.   A wiring diagram is included 
at the end of this manual.  The numbering system for the plug terminals is 1 thru 6 as 
viewed looking at the cage screw heads with wires oriented below (see fig). The 
wire/plug assignments are as follows

  Use the cushioned anchor strap to provide a 

mechanical strain relief for the wires. 

1.

 

“1” connects directly to a nearby 
engine case ground using 18 gauge 
wire.

  Note 1: You cannot rely on the 

ignition’s mechanical attachment to the 
engine to provide ground.  Aluminum 
anodizing acts as an electrical 
insulator, so the clamp connection to 
the anodized flange will not serve as a 
reliable ground.

 

2.

 

“2”  Control Alternate (future use)

 

3.

 

“3”  Control Alternate (future use)

 

4.

 

“4” connects to your ignition 
ON/OFF (ground) p-lead switch 
using 20 gauge wire or larger.

 

 

Note 1:  If you are replacing a 
magneto, your old P-Lead can 
serve this purpose, and may 
already be wired to a suitable 
switch.  Note 2:  Non-starting 
magnetos require a mechanism to 
prevent them from firing during 
start-up. Keyed ignition switches 
have a jumper on the back that serves this purpose.  When installing an E-
MAG in place of a non-starting magneto that was controlled by such a 
switch, make sure you remove this jumper. You do NOT want a start-up 
block on any circuit controlling your E-MAG(s).  

5.

 

“5” connects to your main 12 volt aircraft buss through a dedicated circuit 
breaker (not provided) using 18 gauge wire.  E-MAGs should use a 5-amp 
breaker, and P-MAGs should use a 3-amp switchable breaker.  The 
switch is needed to test the P-MAG  internal alternator during ground run 
up – see Operating Notes. 

 

Note 1:  Whenever the aircraft buss is 

powered up, the ignition is “awake”.  It draws a small amount of current
