GENERAL
The following chart gives the engine types with
their implemented system.
CDI System Identification
➀
RER Dual Trigger Coil CDI (single cylinder)
The RER dual trigger coil CDI system has an igni-
tion coil integrated to the MPEM which is mount-
ed on air silencer.
MPEM is connected to a single ignition generator coil
via a 3-connector housing (BLACK and RED wires).
MPEM is programmed to recognize a signal sent
by the switch located on snowmobile console.
When switch is activated, MPEM cuts off ignition
and engine rev drops at approximately 700 RPM
for 277 engine (Tundra).
MPEM fires a spark at a great advance creating a
thrust which reverses engine rotation.
Second trigger coil located on crankcase takes
over to produce spark in reverse rotation.
A safety device is incorporated to MPEM prevent-
ing it from reading any signal coming from reverse
switch at following engine revs.
Below 800 RPM and above 3500 RPM = no reverse
signal.
