Installation Best Practices & Workshop Advice: Always disconnect the negative battery cable before starting the alternator replacement. Inspect the drive belt condition and maintain appropriate tension on the 10.5 mm V-belt: over-tightening accelerates front bearing wear, while under-tightening causes belt slip and inadequate charging output. Ensure accurate axial alignment between the alternator pulley and engine crankshaft pulley. Clean all terminal contacts on the PL_9104 plug and ground leads to avoid parasitic resistance or voltage drop.
