Diode Testing; Individual Diode; Rectifier - Gauss BT010 Manual Del Usuario

The distribution of terminals may change from one
relay to another. To test them, follow the procedure below:
• Activate the regulator testing module
• Select the rated voltage of the relay (12 Volts or 24 Volts)
• Connect the BLACK cable to terminal "30" and to termi-
nal "85"
• Connect the ORANGE cable to terminal "87"
• Touch the GREEN cable to terminal "86". The relay acti-
vation should be heard and the pilot lamp should light up
• If it's a 5-terminal relay, change the
terminal "87a" and repeat the procedure
3.5.3 Diodo Testing
Diodes are used in alternator rectifiers (rectifier
plates, triodiode). Its function is to allow the current to pass
in a single direction.

3.5.3.1 Individual Diode

To test this type of diode, follow this procedure:
• Activate the regulator testing module
• Positive diode test:
o Connect the ORANGE
cable to the base of the diode
o Watch the "PILOT" lamp, which should light up
o Reverse the cable connections. Now the "PILOT" lamp
should not light up
• Negative diode test:
o Connect the BLACK cable to the rod and the
cable to the base of the diode
o Watch the "PILOT" lamp, which should light up
o Reverse the cable connections. Now the "PILOT" lamp
should not light up
• If the lamp lights up at both connections during the test,
the diode is in SHORT CIRCUIT and not working
• If the lamp does NOT light up at either of the two connec-
tions during the test, the diode is OPEN and not working

3.5.3.2 Rectifier

The rectifier testing procedure is similar to that of
the individual diodes, with the particular detail that the dio-
des are grouped into heat sinks: Positive or Negative.
The figure above shows a rectifier and the equiva-
lent symbology. To perform the test, follow the procedure
below:
• Activate the regulator testing module
• Positive heat sink test:
o Connect the BLACK cable to the positive heat sink
o Touch the tip of the ORANGE
ses (U, V, W)
o The "PILOT" lamp should come on when touching the
orange cable to each phase
o Reverse the connections, securing the
to the positive heat sink
o Touch the tip of the BLACK cable to each of the phases
(U, V, W)
o Now the "PILOT" lamp should not light up when tou-
ching the black cable to each phase
• Negative heat sink test:
o Connect the ORANGE
o Touch the tip of the BLACK cable to each of the phases
(U, V, W)
o The "PILOT" lamp should come on when touching the
black cable to each phase
o Reverse the connections, securing the BLACK cable to
the negative heat sink
o Touch the tip of the ORANGE
ses (U, V, W)
o Now the "PILOT" lamp should not light up when tou-
ching the orange cable to each phase
• If the lamp lights up at both connections during the test,
the diode is in SHORT CIRCUIT
• If the lamp does NOT light up at either of the two connec-
tions during the test, the diode is OPEN
• If the rectifier has shorted or open diodes, the rectifier is
defective and must be replaced
