PREDATOR DC / CDI IGNITION
The Predator has incorporated into it’s design a DC/
CDI ignition system.
Some of the advantages of DC ignition are:
G Stronger, more consistent spark at
low rpm for better performance
G Easier starts
G Simpler component design for ease
trouble shooting and maintenance
Operation Overview:
The DC/CDI system relies on battery power for ignition
function. Instead of generating DC voltage via magnetic
induction, a 12 volt DC current is supplied directly to the
CDI unit from the battery.
At the CDI, the supplied 12 volt DC current charges
an internal capacitor to build up the initial ignition
charge. A small A/C signal from the Pulse coil closes
a thyristor (located in the CDI) at a point
pre--determined in the crankshaft rotation by magnets
on the flywheel’s outer diameter. This signal releases
the electrical charge which saturates the coil for
ignition. DC/CDI systems have the ability to ignite
with as little as 6 volts of power.
NOTE:
DC/CDI systems and compo-
nents are not interchangeable
with any other system.
