1. Disconnect positive battery cable and connect 0-300 scale ammeter between disconnected lead and terminal post.
2. Connect a voltmeter between positive post on battery and starter relay terminal on starter solenoid.
3. Crank engine while observing readings on voltmeter and ammeter. A voltage reading exceeding 0.3 volts indicates a high resistance caused by loose circuit connections, faulty cable, burned starter relay or solenoid switch contacts. High current combined with slow cranking speed indicates a need for starter repair.
4. Reconnect positive battery lead.
