The alternator on your 2003 Protege performs two leading equally considerable functions: to supply the serum needed to endowment all the electronics in the vehivle and to benefit the excess potency it produces to preserve and recharge the battery, as needed. The alternator has two vital values that want testing to verify whether it has failed - voltage and amps. The sluggish voltage on the alternator should be between 13 and 15 volts, whereas the amps should be between 0 and 59 at 1,000 rpm, and between 0 and 77 at 2,000 rpm. Provided either corroboration fails on your 2003 Protege, moderate the alternator.
Instructions
1. Loosen the denying battery cable aim with a combination wrench and pull the contravening cable from the battery. Position it elsewhere of the idea to prevent unexpected reconnection.
2. Remove the competence wire from the alternator by loosening its retaining seed with a ratchet and socket and pulling the wire from its stud. Press and control the unlocking Press-stud on the alternator wiring harness and pull the harness from the alternator.
3. Loosen the upper and lower mounting bolts on the alternator, using a ratchet and socket. The lower bolt goes completed the rear of the lower alternator mount and the upper bolt goes down the alternator's adjuster bracket.
4. Advice the tension on the alternator propel zone by turning the adjusting bolt clockwise with a ratchet and socket. Hang in loosening the adjuster bolt until the operate cummerbund is loose Sufficiently to slide off the alternator pulley.
5. Pull the sash from the alternator pulley, on the other hand liberty it attached to the remaining pulleys.
6. Remove the upper and lower alternator bolts with a ratchet and socket, and pull the alternator from the Protege's engine compartment.
7. Adviser the advanced alternator into the engine compartment, inserting the mount on the backside of the alternator into the mount on the engine. Encompass the lower alternator bolt complete the bolt holes in the backside of the alternator and its bracket, then hand-thread the lower alternator bolt.
8. Spindle the alternator upward and straighten its upper bolt-hole with the bolt-hole in the alternator adjuster bracket. Hand-thread the upper alternator mounting bolt.
Plug the wiring harness into the rear of the new alternator. Guide the alternator power wire onto its mounting stud and hand-thread its nut. Tighten the power wire nut to between 8 and 11 foot-pounds with a torque wrench and socket.12.
Tighten the upper alternator mounting bolts to between 14 and 18 foot-pounds and the lower alternator mounting bolts to be between 28 and 38 foot-pounds, using a torque wrench and socket. The upper bolt also acts as the locking bolt for the belt adjuster.
11.9. Route the coerce cestuses back over the alternator pulley, then turn the adjuster bolt counterclockwise until the region reaches its equitable tension of aloof over a 1/4 inch - 0.26 to 0.29 inches to be precise - of deflection at the middle of its longest span between pulleys.10.
Reconnect the negative battery cable end to the negative battery terminal and tighten its pinch bolt with a combination wrench.
