Connect the 12 V battery to the OLe/fuel pump sub
harness 4P (Red) connector (turn the "ECM" selector
switch ON) (page 5-12).
Check the initial voltage at this lime.
The battery voltage should be measured.

Disconnect the 12 V battery (page 5-12).
Shift the transmission into neutral.
Crank the engine with the kickstarter and read the
ignition coil primary peak voltage.
