The resistor is a back up in case the charging indicator bulb fails, this allows the charging system to continue to operate normally. If the resistor is not in the circuit and the charging indicator bulb fails your charging system will not operate. Since the bulb does not illuminate in this situation you may or may not realize that the fault with the system is the bulb and not another component in the charging system.

The diagram that I posted is directly from the 1964 Ford training manual for the Ford charging system with an alternator and with or without the amp meter. This manual is applicable to the 289 Cobras equipped with the Ford, wiring harness, alternator, regulator and Stewart Warner gauges.
