Symbol Meaning Symbol Meaning
Battery (I, Generates electricity through Resistance l A resistor with a constant value
chemical reaction l Mainly used to protect electrical
l Supplies direct current to circuits components in circuits by maintaining
rated voltage
l Reading resistance values
Ground (1)
l Connecting point to vehicle body or No.1 Cobr band
-A- other ground wire where current flows -No.2 Cobr band
from positive to negative terminal of -No.3 Cobr band
battery No.4 Cobr band
1
l Ground (1) indicates a ground point to Flnt color. Rerkrancs
body through wire harness
Ground (2) l Gound (2) indicates point where
component is grounded directly to body
Remark
oCurrent wilt not flow through a circuit if
ground is faulty
Fuse (1)
(box)
Fuse (2)
l Melts when current flow exceeds that
specified for circuit, stopping current
flow
Precautions
o Do not replace with fuses exceeding
specified capacity
