Battery current leakage inspection
Inspect the battery current leakage in the following
procedures:
turn the ignition switch off.
Remove the front seat. Refer to “exterior parts
removal and installation” in section 9d (page 9d-
6).
Disconnect the battery (–) lead wire.
Measure the current betwee ...
Continuity check
Measure resistance across coupler “b” (between “a”
and “c” in figure).
If no continuity is indicated (infinity or over limit), the
circuit is open between terminals “a” and “c”.
Disconnect the coupler “b” and measure resistance
between couplers “a” and “b-1”.
If no continuity ...
