DR-19A Fault Code 41-47 or 41 Charging System

1. Connect a voltmeter between battery terminals.
2. Connect a jumper wire to a good engine ground.
3. Start engine and note voltmeter reading.
4. Contact other end of jumper wire connected to engine ground to alternator F2 terminal and note voltmeter reading.
NOTE: The alternator field terminals of the engine wiring harness (F1 and F2) on the Shelby Charger are interchangeable. Therefore, it will be necessary to identify which one is F1 (Ignition switchfeed) and which one is F2 (Field control to power module) before performing the tests.
5. If voltmeter indicates an increase in voltage reading, proceed to Test 19 step B.
6. If voltmeter does not indicate an increase in voltage reading, proceed to Test 19 step E.
