With the ignition off, measure the voltage between the negative
battery terminal and the power fuse output.
Is the voltage greater than or equal to 10V?
The power fuse is sound The power fuse is faulty
With the battery disconnected, measure the resistance between
the negative battery terminal and the power fuse output.
Is the resistance
≥ 10 Ohms?
Disconnect the alternator + terminal and
then measure the resistance between the
