INITIAL CHECKS
Before proceeding with charging system diagnosis, ensure: Battery is fully charged and in good condition
Battery cables are in good condition with connections clean and secure
Alternator belt is in good condition and properly tightened
Alternator and SBEC wiring harness connections are clean and tight.
Engine ground strap is in place
UNSTEADY OR LOW CHARGING
Check for loose alternator belt, charging resistance too high, defective alternator, loose alternator ground wire or corroded battery terminals.

Chedck and test the fusible link and the dark blue at the alternator for battery voltage coming from the ignition switch
