can be located next to each other on the panel, making these tests one-handed, intuitive, and more
ergonomic. Two examples are shown below the Wiring Diagram at the end of this manual.
Control Plug Wiring
1)
Plug Styles:
a)
Standard circular Mil plug connector (PT06A-10-6S-SR or similar). This is a solder
connection style plug with built-in strain relief clamp for attaching (20 AWG) control wires.
Note:
Standard plug is roughly ½” longer than the optional potted plug (below) - in case
clearance is tight.
b) Optional circular plug connector with pig tail
– circular connector (PT06P-10-6S or similar)
with 96
” of wire soldered and potted – see color references below and wiring schematic at
the end of the manual
.
2) Pinouts:
a)
Pin “A”
on circular plug
(Pig-Tail red wire)
- connects to your 14, 28, or 48-volt aircraft bus
– 20 AWG -
see Note 8
. Route through a power test switch and suitable circuit protection.
Possibilities are:
i) A separate 5-amp fuse and separate power test switch.
ii) A 5-amp switchable circuit breaker, which can satisfy circuit protection and power test
duties.
b)
Pin “B”
(Pig-Tail black wire) -
connects to the cockpit panel ground
– 20 AWG.
c)
Pins “C” and ”D”
(Pig-Tail white and green)
– stow for future use – 22 AWG.
d)
Pin “E”
(Pig-Tail yellow wire) -
connects to your cockpit kill switch (p-lead ignition
ON/OFF). To turn ignition OFF, ground the p-lead with the switch. To turn ignition ON, un-
ground the p-lead Kill Switch (*) 22 AWG.
e)
Pin
“F”
(Pig-Tail blue wire)
– connects to tach instrument (3 pulses per rev) 22 AWG
(*) Mode Switch (optional): Ignitions can work with a
cockpit switch to select either Fixed Mode or Variable
Mode operation. The switch circuit adds a 1K bias
signal to the existing kill wire (pin E)
to enable Fixed
Mode operation. The switch E-MAG offers is a SPDT
(one switch controls two ignitions) with 1K resistors pre-
installed. Mode Switch is optional on normally
aspirated engines but is required on boosted engines.
Note 1: Shower or vibrator type starting aids are not compatible and may damage your E-MAG
–
remove before installation.
Note 2: E-MAG p-lead wire does not make radio noise and does not require shielding. If replacing
a magneto, your existing shielded p-lead wire can be re-used. If doing so, the outer shield needs to
be trimmed clean and kept well clear of all other terminations.
Note 3: All E-
MAGs are “starting ignitions”. In a dual installation, or if replacing a non-starting
