Hello i'm a tunisian student and i have a project to improve this tester
plz anyone can help me


Features:


• Test A and B Type Circuit Alternator Regulators
• Test 12V, 24V, and 32V Alternator Regulators
• Test Field Circuit with 0.5A, 3.0A, or 5.0A Load
• Identify Active L-Terminal (Choke Drive)
• Identify Presence of Over-Voltage Function
• Identify Presence of Field Diode
• Warning Light Circuit to Simulate Vehicle Indicator Lamp
• Short Circuit Lamp to indicate Regulator Short Circuit Overload
• Stator Output Signal for Testing Delco CS-Series and Other Types with this
Requirement
• Lead Set and Test Manual Provided
OPERATING INSTRUCTIONS FOR VRC1000
1. Set the field current switch to 0.5A for checking or setting the
regulation voltage. Set the field current switch to 3A for burn-in.
2. Set the "FIELD" switch to "A" or "B" according to the tester
information given on the tester instructions.
"A" Circuit - The "A" circuit regulator design has one alternator
field lead connected to battery (or trio) and the other end of the
field is controlled or switched to ground by the regulator.
"B" Circuit - The "B" circuit regulator design has one alternator
field lead connected to ground and the other field is controlled or
switched to the battery (or trio) by the regulator.
3. Connect test leads according to tester instructions for the
regulator being tested and follow all information given by notes
and additional tests when applicable.
4. Select the "Voltage Range" (12v, 24V, and 32V) for the regulator
being tested and turn the power switch to the "ON" position.
5. If the short circuit light comes on, quickly turn the tester "OFF".
The short circuit light indicates that battery positive is being
shorted to battery negative. However, when testing some vibrator
contact regulators such as Ford GRB-5440 or Delco 1119519, the
short circuit light will come on which is alright if the field
light blinks. However, do not test the vibrator contact regulators
longer that two minutes. Should the tester fail due to overload,
check the fuse. The Transpo VRC1000 is not to be used to check D.C.
generator regulators. The tester is designed to be used to test
alternator regulators only.
TEST RESULTS "GOOD REGULATOR"
The regulator is operating correctly if the field light blinks and
the digital meter displays approximately the set point voltage
given on the appropriate tester instructions. Sometimes it may be
necessary to adjust the voltage setting on those regulators that
are adjustable. See the tester instructions for the regulator being
tested.
TEST RESULTS "BAD REGULATOR"
Full Field - The digital meter will indicate approximately 16.5V
for a 12V regulator, 29.5V for a 24V regulator and 42V for a 32V
regulator. The field light will not blink but will remain "ON".
A regulator with this type of defect will not be able to control
the output voltage of the alternator
