Current Output
- With test connections made as for Charging Circuit Resistance, disconnect voltmeter negative lead from positive terminal of battery and reconnect to ground (see illustration). Connect a tachometer to engine. Start engine and operate at 1250 RPM. Adjust carbon pile to obtain a reading of 15 volts on test voltmeter and note reading on ammeter. Current output should be within specifications.
- If output is slightly less (5-7 amperes) than specified, it may be an indication of possible open rectifier or other alternator internal problem. If output is considerably lower, it may be an indication of a possible shorted rectifier or other alternator internal problem.
