It uses an internal regulator, insulated return, and pad mount arrangement, with mount centres of 108mm on one side and 126mm on the other, plus a mount leg thickness of 80mm.\u003c\/p\u003e\n\u003cp\u003eThis alternator is a brushless OE product with lamp terminal, AC (R) terminal, self-exciting function, and sense terminal. It has a 22mm shaft diameter, clockwise rotation, and no pulley section applicable, which are important checks when matching to an existing charging system or replacement assembly.\u003c\/p\u003e\n\u003cp\u003eThe unit is listed for extreme mining applications and carries the note that it is not compatible with diode type battery isolators. For dual alternator applications, the R214107437S regulator is required to be installed. Those two points are important to confirm before ordering, particularly where the vehicle already has auxiliary charging equipment fitted.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e24V alternator with 185A power rating\u003c\/li\u003e\n\u003cli\u003eNew unit, sold individually\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eBrushless OE product\u003c\/li\u003e\n\u003cli\u003eLamp terminal and AC (R) terminal\u003c\/li\u003e\n\u003cli\u003eSelf-exciting with sense terminal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart No.: BLP4112M\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: 185A\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\u003eBefore ordering, confirm the part number BLP4112M against the alternator currently fitted, along with the 24V system voltage and 185A output requirement. The mounting dimensions are specific: 108mm mount centres A, 126mm mount centres B, and 80mm mount leg thickness. If those measurements do not align with the vehicle’s existing bracketry, the alternator will not be a direct physical match.\u003c\/p\u003e\n\u003cp\u003eThe shaft diameter is 22mm, the rotation is clockwise, and the pulley section is listed as not applicable. Those details matter when comparing against the removed unit, because pulley style, shaft size, and rotation must match the application. The unit also has an internal regulator, so it is best suited to systems designed for that regulator type rather than an external-regulated arrangement.\u003c\/p\u003e\n\u003cp\u003ePay close attention to the electrical connections as well. This alternator includes a lamp terminal, AC (R) terminal, and sense terminal, and it is self-exciting. It is also noted as not compatible with diode type battery isolators. If the vehicle uses that type of isolator, this alternator should not be assumed suitable without confirming the charging setup first.\u003c\/p\u003e\n\u003cp\u003eFor dual alternator applications, the stated requirement is that regulator R214107437S must be installed. That is a specific installation condition and should be checked against the vehicle’s existing charging system before purchase. The alternator is also described as designed for extreme mining applications, so it is intended for demanding use where the correct electrical configuration is essential.\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 BLP4112M 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) 185, 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. BLP4112M, Brand PRESTOLITE, Description Prestolite Alternator 24V 185A, 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 185A.
