Troubleshooting Hints - Starting System

Visually inspect the hydrometer (built into Battery).
^ Green eye - Battery is charged.
^ Dark eye - Charge and load test Battery. If Battery passes load test, refer to Diagnostic Charts.
^ Clear or light yellow eye - Battery electrolyte is low. Replace Battery.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.

Important: The following tests are designed for engines and batteries at normal operating temperatures and assumes that there are no engine symptoms which would cause a no-start symptom. The Battery must be in a charged state before doing diagnosis. To use the tests under other conditions could result in misdiagnosis.

1. Check that Starter Solenoid terminals "S" and "B" and Battery connections are clean and tight.
2. Check that G100 and G101 are clean and tight. Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check. Use Test Light J 34142 whenever possible. Test lights require more current than a high impedance DVM and are more useful for detecting abnormally high resistive circuits. Some test lights have high impedances and will not be as useful in detecting resistive circuits.
