Circular plug (ignition)
Circular plug (cable)
Control Plug Wiring
1)
Plug styles:
a) Standard
circular Mil plug connector (PT06A-10-6S-SR or equivalent). 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) - if case
clearance is tight
.
b)
Optional
circular plug connector with pig tail
– circular connector (PT06P-10-6S or
equivalent) with 96” of color-coded 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 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 not populated)
– for future use.
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 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:
CAUTION]
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
magneto, revise your starting procedures, and/or remove any key switch starting blocks (remove
the jumper on the back of the key switch) to your E-MAGs.
Note 4: Whenever the aircraft bus is powered ON, the ignition is “awake”. It draws a small amount
of current (approx. 40 milliamps) even when not firing plugs. Use the master bus switch (or
