Product Information

45-0428 STAMFORD® Diode Kit for UC22/UC27 STAMFORD® Alternator

The 45-0428 STAMFORD® Diode Kit works specifically with the UC22/UC27 STAMFORD® alternator. The kit includes:

3 Forward (Positive) Diode Leads – Connected to the Rectifier Plate
3 Reverse (Negative) Diode Leads – Connected to the Rectifier Plate
1 Varistor (Surge Suppressor)

A damaged diode can cause electrical leaks, unwanted noises, battery drain and ultimately an alternator to fail. The best way to prevent this is to make sure your diodes are new and original STAMFORD® parts.

This kit is compatible with the UC22/UC27 STAMFORD® alternator and is 100% authentic STAMFORD® | AvK® parts. Only authentic STAMFORD® | AvK® parts extend the manufacturer warranty.
