PEAK VOLTAGE MEASUREMENT

NOTE:
S If the spark produces no sparks, check the wir-
ing for any disconnection, looseness, insuffi-
cient contact, etc. Then measure the peak volt-
age.
S The peak voltages are listed for the connected
and the open state. The "connected value" is
used for measuring a normally operating sys-
tem and the "open valve" for measuring a coil
disconnected from the system.
S The peakvoltage value measured at cranking
is the one at which no load is applied to the jet
pump.
S To measure the peak voltage of lighting coil
and rectifier regulator, take off the output wire
of the rectifier regulator.
Measuring step:
S Remove the electrical box and disassem-
bly it.
Refer to "ENGINE UNIT REMOVAL".
S Attach the tachometer to the high tension
lead of the cylinder #1, (No need during
cranking measurement).
S Set the peak voltage adaptor to the tester.
NOTE:
The peak voltage adaptor plugs a have po-
larity. Connect the red plug of the peak volt-
age adaptor to the volt test plug of the tester.
