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.

GENERATOR OUTPUT
- Connect an ammeter (100-amp minimum) in-line between generator terminal "B" connector and terminal "B" of wiring harness connector. (Scheme 11) Turn headlights and all accessories on. Depress brake pedal. Operate engine at 2500-3000 RPM.
- If amperage is not as specified, see GENERATOR MAXIMUM RATED OUTPUT table, repair or replace generator as necessary. If amperage is as specified, turn off headlights and all accessories. Release brake pedal. Operate engine at 2500-3000 RPM. If amperage is not about 5 amps or more, repair or replace generator as necessary.
- If amperage is about 5 amps or more, measure voltage between ground and terminals "S" and "L" while operating engine at 2500-3000 RPM. If 14.1-14.7 volts is not present, repair or replace generator as necessary. If 14.1-14.7 volts is present, generator output is okay.
| Application | Amps |
|---|---|
| 4-Cylinder | 80 |
| V6 | 90 |

ROTOR & SLIP RINGS
Measure resistance between rotor slip ring contacts. (Scheme 16)-10. If resistance is not within specification, replace rotor. See ROTOR RESISTANCE SPECIFICATIONS table. Check continuity between individual slip rings and rotor core/shaft. If continuity is present, replace rotor.
| Application | Ohms |
|---|---|
| MX-6 | (1) 2.5-3.5 |
| (1) If continuity is not present, replace rotor. | |
| (1) | If continuity is not present, replace rotor. |

STATOR
Check continuity between stator coil leads and stator core. (Scheme 16)-10. If continuity is present, replace stator. Check continuity between leads of stator coil. If continuity is not present, replace stator.
BRUSHES
Replace brushes if worn to limit line. (Scheme 16)-10. Replace brush springs if corroded. For brush replacement procedure, see OVERHAUL.
