Product Number: 7853N-140A
The WAI 7853N-140A is a brand-new 12V 140A alternator. It is built to the Delco 15SI IR/EF design, offering a direct-fit replacement for machines and vehicles originally equipped with this specification. With a clockwise rotation and groove pulley configuration, it is engineered to meet the output demands of the applications for which the 15SI IR/EF format was designed.
The 15SI designation identifies the internal regulator and end-frame type, a well-established Delco platform widely used across industrial, agricultural, and commercial vehicle applications. The IR/EF configuration means the voltage regulator is integrated within the unit — no external regulator is required. At 140A output, this alternator handles high electrical loads reliably.
This unit is cross-referenced under Lester number 7853 and PIC number 240-247A, amongst other catalogue references, making it straightforward to verify against existing parts records.
