3 EXTERNAL VOL TS LEADS (1 mg ohms) These leads may be used for measuring any DC voltage on a vehicle when the test selector switch is placed in External posi- tion. The voltmeter circuit is isolated and has an automatic polar- ity indication. T ypical applications are for measuring load volt- ages and cable connection voltage drop s.
4 readings are taken, the battery should be charged five minutes to stimulate mixing. (Refer to battery manufacturer ’s instructions regarding removal of vent caps while charging battery). ELECTROL YTE CAUTION Battery electrolyte is SULFURIC ACID. It can eat holes in clothes and skin.

7 AL TERNA TOR SYSTEM TESTS The following test procedures will determine if there is a problem in the diode stator , voltage regulator , electrical load requirements, or in the alternator amperage output. The test s can pinpoint prob- lems to the wires and connection between the charging output terminal, the regulator , the field, and the battery .
8 Causes of high voltage drop s can be from LOOSE OR COR- RODED CONNECTIONS at the output terminal of the alternator , the car ’s ammeter , battery terminal connection on the starter so- lenoid, battery cable connections, faulty wiring from alternator to regulator , to ammeter , to starter solenoid, or between the alter- nator and the engine.
