CHARGING SYSTEM

CHECKING THE LIGHTING COIL
1. Measure:
• Lighting coil resistance
Out of specification → Checking the
peak voltage.
Lighting coil resistance:
0.31 - 0.37 Ω Ω Ω Ω
Measuring steps
(1) Disconnect the Green (G) leads from
the wire harness.
(2) Connect the tester to the lighting coil as
shown.
NOTE:
When measuring the resistance of 10Ω or
less using the digital tester, the correct
measurement cannot be obtained.
Refer to "M EASURING A LOW RESIS-
TANCE" on page 8-3.
2. Measure:
• Lighting coil output peak voltage
Below specification → Replace.
