#2 - VISUAL / MULTI-METER CHECKS
CHECK A – Varistor/Capacitors
(Varistor/Capacitors)
Visual inspection:
- Check that the varistor and the capacitors are not
damaged.
Damage types may be:
1- Exploded/blown component.
2- Broken component.
Multi-meter check:
- None.
Check result:
- If the result of all the above checks has been
positive, tick the ok box in section #2 of the report
form, Check A.
Otherwise leave the box blank.
In case of component failure:
Possible effects on regulation:
- The alternator output voltage is lower than the rated voltage and equal to the residual one.
You cannot set the proper value using the VOLT trimmer.
- None.
Possible failure causes:
- Mechanical damage due to impact/shock.
- Voltage exceeding 420Vrms between terminals P1 and P2 due to alternator overvoltage.
- Improper connection, which resulted in a voltage higher than 420Vrms between terminals P1 and
P2.
Actions:
- Replace the AVR.
