Symbolic notation of the modern generators voltage regulator outputs are shown in Appendix B.
A vehicle system voltage and a
voltage of cut-off stabilization (such voltage has sizable fluctuation for different
diode types) are marked in catalogs.
2.3.3. Usable regulator must have a stabilization voltage corresponding to the specified in paragraph 2.4.3.2.

2.3.11. Connecting of other probes depends on design and codes for voltage regulator terminals.
2.3.12. Connect clips of probes to the correspond marked voltage regulator outputs.
2.3.13. Ensure the secure regulator fixation on a dielectric lining.
2.4.
The voltage regulator integrated control.
2.4.1. The integrated control includes 6 modes of tester run (
А
, B ,C, D,

), that can detect all of the major
regulators defects.
2.4.2. Make preparations for holding the tester control in accordance with article 2.3.

2.4.3.2. Usable regulator must have a stabilization voltage corresponding to the specified in a housing or in
cataloges.
Tolerance is no more than 0,1 V for regulators 12 V; - no more than 0,2 V for regulators 24 V.
CAUTION
!
If there is a short circuit a indicator

overheating large power
wire ballast resistors will appear in a tester housing. The time of probes contact should not exceed 5 s for the
avoidance of tester crash.
