BELT DEFLECTION

Measure belt deflection in center of longest pulley-to-pulley span. See BELT DEFLECTION SPECIFICATIONS table. If belt deflection is not as specified, adjust as necessary.

Application(1) Deflection - In. (mm)
2.3L
New Belt0.22-0.26 (5.5-6.5)
Used Belt0.26-0.30 (6.5-7.5)

(1) With 22 lbs. (10 kg) applied to belt. (2) Tension is controlled by an automatic adjuster. No adjustment is required. If belt tensioner has reached its limit of travel, replace belt.

* PLEASE READ FIRST *

Note. Check generator wiring harness connections and drive belt tension. Battery must be fully charged before testing. Wait at least 30 seconds after starting engine before measuring system voltage.

CAUTIONEnsure generator terminal "B" does not contact ground.

GENERATOR OUTPUT

  1. Connect an ammeter (100-amp minimum) in-line between generator terminal "B" connector and terminal "B" of wiring harness connector. (Scheme 15) Turn headlights and all accessories on. Depress brake pedal. Operate engine at 2500-3000 RPM.
  2. Measure and record generator output. See «GENERATOR MAXIMUM RATED OUTPUT»(ref-124856-S16708779592001100200000) table. If amperage is as specified, go to next step. If amperage is not as specified, repair or replace generator.
  3. Turn off headlights and all accessories. Release brake pedal. Operate engine at 2500-3000 RPM and measure amperage under no-load condition. No-load amperage should be 5 amps or greater. If amperage is as specified, go to next step. If amperage is not as specified, repair or replace generator.
  4. Operate engine at 2500-3000 RPM. Measure voltage between ground and terminals "S" and "L". If 14.1-14.7 volts does not exist, repair or replace generator. If 14.1-14.7 volts exists, generator output is okay.
