Diodes are used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators and oscillators. The basic property of a diode is that it tends to conduct current in one direction only.

What role do diodes play in a generator?
A diode is a device placed in an electrical circuit to conduct electrical current. They allow current to move easily in one direction but not the other.

What are the symptoms of a bad diode in a generator?
A faulty diode will cause the bulb to emit light in both forward and reverse directions (short-circuited diode), or not emit light in either direction (open-circuit diode). If one or more diodes are found to be defective, be sure to replace the entire set. Insulation resistance to ground low voltage generator 100 – 690VAC.

What causes generator diode failure? Common causes of diode failure are excessive forward current and excessive reverse voltage.

How do i know if the diode is damaged?
A diode only conducts electricity in one direction and the voltage drops. If the measured forward voltage drop does not meet the specifications (check the data sheet), the diode is bad and should not be used. If it measures no forward voltage drop or continuity at all (beep), the diode is actually bad.

Which Diodes does WDPART supply?
