Replacing a soldered bypass-diode in a ProCharger™-CR-junction box
Replacing a bypass-diode in
a Spelsberg-junction box
}
Check the conductivity of the diodes. They
should conduct electricity when the test
leads are connected in one direction and
show a high resistance in the other direc-
tion. If a diode conducts in both direc-
tions, it is defective.
}
Replace a defective diode with a diode of
the same type, and ensure that its polarity
marking is oriented the same way as the
original diode.
}
Finally, check the open-circuit voltage of
the module and replace both covers.
ProCharger™-S junction box
}
Open the cover and remove the diodes by
cutting their leads with a wire cutter. Note
the orientations of the polarity markings
on the diodes.

Replace a defective diode with a diode of
the same type, and ensure that its polarity
marking is oriented the same way as the
original diode. Solder the leads of the
diode to the contacts.
}
Finally, check the open-circuit voltage of
the module and close the cover.
Spelsberg junction box
}
Open the cover, and remove the diodes
by pressing on each terminal with a small
flat-blade screwdriver and extracting the
diode lead. Note the orientations of the
polarity markings on the diodes.
