note: This is a CS144 Unit. 145A. Previous Lester Catalogs Also Referred Similar Looking 124A Units as the 7684-11. We Have Re-Numbered These to 7678-11. The 7684-11 (#425 Regulator) Looks Like the 8112-5 (140A - #429 / #437 Regulator) and the 8183-5 (140A - #412 Regulator) in That All Have the Same Unthreaded Top Mounting Ear and the Same Rear Housing, But the 7684-11 Also Uses a Molded Battery Terminal Insulator That Points Outward at 7: 00. The 7969-2 (140A - #413 / #430 Regulator) Looks Like the 7684-11, But Uses a Threaded Top Mounting Ear on the Front Housing. The 7684-11 Uses the 1255 Pulley.
