W ARNING
The DIt ignition system presents a serious shock hazard. The primary circuit operates at 300 volts; the
secondary circuit operates in excess of 35,000 volts. Use caution to avoid injury from shock, or injury
from your reaction to shock. Do not handle primary or secondary ignition components while the engine
is cranking or running.
