Mallory Ignition Mallory MAGNETO IGNITION SYSTEMS SPRINTMAG, SPRINTMAG II,III - Manual (Page 2)

GENERAL INFORMATION
• Closely monitor spark plugs and spark plug gaps for
maximum performance. Set spark plug gaps at .018" to
.022".
• 16AWG/600V or larger wire must be used on all additional
wiring. All grounds must be made to the engine block. Do
not ground to chassis or anodized surfaces.
WARNING
• A KILL SWITCH MUST BE USED TO STOP THE ENGINE
FROM RUNNING.
• NEVER CONNECT ANY PART OF THIS IGNITION TO 12
VOLTS.
• Disconnect and remove generator before arc welding
on the vehicle.
• On dual ignition systems, each ignition system must run
independent of the other.
• To prevent internal damage to transformers, the
transformer must be mounted with the high tension lead
coming from the bottom and positioned no closer than
2.5" from the nearest metal surface.
SPRINTMAG AND SPRINTMAG II MAGNETO STARTING TIP
A magneto normally requires good crankshaft speed to
produce enough ignition output to start the engine. When the
magneto is hot, higher crankshaft speeds are required. The
Mallory Magneto Start Assist Box is designed to electronically
connect the magneto system to the engine's starter solenoid.
During starting, the Magneto Start Assist Box "boosts" the
magneto output, creating a strong starting spark even at very
low cranking RPM. IMPORTANT: The magneto must be
modified at the factory before it can be used with the
Magneto Start Assist Box. Ship your magneto to:
