Product Number: 21832N
The WAI 21832N is a brand-new 12V 100A alternator. It is built to replace Hitachi original-equipment units, including Hitachi LR1100-503 and its variants (LR1100-503A through LR1100-503F) — seven OE references in total. Designed as a direct-fit replacement, it is matched to Opel passenger and light commercial vehicle applications across five fitment variants, including the Corsa C, Corsa D, Meriva A, and Corsa/Combo II.
The unit runs an internally regulated, internally fused (IR/IF) design, which eliminates the need for an external voltage regulator and simplifies installation. Clockwise rotation and a single-claw SC6 pulley are specified, ensuring compatibility with the original drive-belt configuration. The Lester reference for this unit is 21832.
As a WAI product, this alternator is supplied brand new — not remanufactured — giving a clean installation with no worn internals to contend with. It is catalogued against both Opel and Opel LCV platforms, covering three Opel and two Opel LCV model lines.
