It is an OE product from Prestolite and is specified with an internal regulator, insulated return, and clockwise rotation, making the key electrical and mounting details easy to verify before purchase.\u003c\/p\u003e\n\u003cp\u003eThis alternator uses a pad mount with 108mm mount centres A, 126mm mount centres B, and a 22mm shaft diameter. The leg thickness is 80mm and the pulley section is not applicable, so the physical mounting arrangement and drive setup should be checked against the existing unit rather than assumed.\u003c\/p\u003e\n\u003cp\u003eIt is described as brushless and self-exciting, with lamp terminal, AC (R) terminal, and sense terminal connections. The unit is also noted as being designed for extreme mining applications, which is relevant when the application calls for a heavy-duty 24V charging solution.\u003c\/p\u003e\n\u003cp\u003eFor dual alternator applications, the note states that regulator R214107437S is required to be installed. It is also noted as not compatible with diode type battery isolators, so the charging system layout needs to be confirmed carefully before ordering.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePrestolite OE product\u003c\/li\u003e\n\u003cli\u003e24V, 275A output\u003c\/li\u003e\n\u003cli\u003eBrushless design\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eSelf-exciting\u003c\/li\u003e\n\u003cli\u003eLamp terminal, AC (R) terminal and sense terminal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: BLP4111M\u003c\/li\u003e\n\u003cli\u003eBrand: Prestolite\u003c\/li\u003e\n\u003cli\u003eProduct type: Alternator\u003c\/li\u003e\n\u003cli\u003eVoltage: 24V\u003c\/li\u003e\n\u003cli\u003ePower rating: 275A\u003c\/li\u003e\n\u003cli\u003eMount type: Pad\u003c\/li\u003e\n\u003cli\u003eMount centres A: 108mm\u003c\/li\u003e\n\u003cli\u003eMount centres B: 126mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eConfirm the part number BLP4111M first, then compare the mounting pattern, shaft size, and rotation to the alternator you are replacing. The listed 24V, 275A output and pad mount with 108mm and 126mm mount centres are the most useful checkpoints for matching the unit physically and electrically.\u003c\/p\u003e\n\u003cp\u003eThe internal regulator and insulated return matter when checking how the vehicle’s charging system is wired. This alternator is also stated to be not compatible with diode type battery isolators, so if the machine uses that style of isolator it needs to be identified before purchase.\u003c\/p\u003e\n\u003cp\u003eIf the vehicle is a dual alternator application, the note specifically calls for regulator R214107437S to be installed. That requirement should be checked as part of the full charging system setup, not left until installation day.\u003c\/p\u003e\n\u003cp\u003eThe unit is listed as brushless, self-exciting, and fitted with lamp terminal, AC (R) terminal, and sense terminal connections. Those details help when matching the wiring arrangement on heavy-duty equipment, especially where the original alternator has a similar connection layout.\u003c\/p\u003e\n\u003cp\u003eBecause this alternator is described for extreme mining applications, it suits buyers looking for a heavy-duty Prestolite 24V charging component with a 275A rating. Even so, the safest approach is to verify the old unit’s part number, mount centres, shaft diameter, and regulator arrangement before placing the order.\u003c\/p\u003e\n\u003cp\u003eBefore supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number BLP4111M helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Mount Centres B 126mm, Power Rating (Amp) 275, Regulator Type Internal, Shaft Diameter 22mm, Voltage 24, Alternator Mount Pad, Insulated Return Yes.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. BLP4111M, Brand PRESTOLITE, Description Prestolite Alternator 24V 275A, Mount Centres A 108mm, Mount Leg Thickness 80mm, Pulley Section Not Applicable, Rotation CW, Suits Unit Make Prestolite.\u003c\/p\u003e\n\u003cp\u003ePrestolite Alternator 24V 275A. Part number BLP4111M should be checked first. Listed voltage is 24. Listed output rating is 275. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Pad. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number BLP4111M, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 and output 275 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eWhere no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.\u003c\/p\u003e\n\u003cp\u003eIn the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.\u003c\/p\u003e\n\u003cp\u003eThe listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Please confirm fitment using part number BLP4111M, the 24V 275A specification, the pad mount with 108mm and 126mm mount centres, and the wiring\/regulator details before purchase. If the vehicle uses diode type battery isolators, or if it is a dual alternator application, check the stated requirements carefully.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the part number for this alternator?\u003c\/h4\u003e\n\u003cp\u003eThe part number is BLP4111M.\u003c\/p\u003e\n\u003ch4\u003eWhat voltage and output rating does it have?\u003c\/h4\u003e\n\u003cp\u003eIt is a 24V alternator with a 275A power rating.\u003c\/p\u003e\n\u003ch4\u003eIs this a new or remanufactured unit?\u003c\/h4\u003e\n\u003cp\u003eThis alternator is listed as new.\u003c\/p\u003e\n\u003ch4\u003eWhat mounting details are provided?\u003c\/h4\u003e\n\u003cp\u003eIt is a pad-mount alternator with mount centres A of 108mm, mount centres B of 126mm, and a mount leg thickness of 80mm.\u003c\/p\u003e\n\u003ch4\u003eDoes it have an internal regulator?\u003c\/h4\u003e\n\u003cp\u003eYes.
