6.9—7.5 ohms [20°C {68°F}]


Spool Valve Operation Inspection

1.Verify that the spool valve inside the OCV is at the position shown in the figure.

• If there is any malfunction, replace the OCV.

Note
• When applying battery positive voltage between the OCV terminals, the connection can be either of the following:
― Positive battery cable to terminal A, negative battery cable to terminal B
― Positive battery cable to terminal B, negative battery cable to terminal A

2.Verify that the spool valve moves in the direction shown in the figure when battery voltage is applied between OCV terminals A and B.

• If there is any malfunction, replace the OCV.
