Over repeated thermal cycles, OEM solenoid contact points oxidize and pit, triggering the familiar single click or rapid-fire clicking symptom without engine turnover. Additionally, worn copper bushings cause armature misalignment, increasing internal friction that leads to high amperage draw, slow cranking speeds, and premature ring gear teeth wear from improper pinion engagement.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement starter utilizes an efficient Permanent Magnet Gear Reduction (PMGR) design, reducing physical weight and electrical draw while maximizing break-away cranking torque. Built with a heavy-duty copper-wound solenoid, high-temperature insulated armature coils, and a case-hardened alloy steel drive gear, it eliminates slow cranking and withstands prolonged heat exposure.
