SSAYEC432 Diode Kit
The SSAYEC432 Diode Kit is supplied under part number SSAYEC432 for alternator exciter repairs.
About this part
In a brushless alternator the exciter produces AC on the rotor, and a set of diodes turns it into DC for the main field. A varistor across the bridge absorbs voltage spikes that would otherwise destroy the diodes.
When to replace it
- Low output voltage with the AVR at full excitation
- AVR failing repeatedly
- A shorted or open diode found on testing
- Burnt varistor after a surge
Before you order
Observe diode polarity (forward and reverse types) when fitting, and torque the terminals to avoid hot joints.
If the old part has no readable number, send us a clear photo with the engine or alternator nameplate and we will identify it before you buy.
Questions
How do I test a rotating diode?
Disconnect it and check it with a multimeter on diode test: it should conduct in one direction only. Replace any that read short or open both ways.
