harder to pedal. If no resistance is felt then the alternator has a problem.

Test the diode. Unplug the diode from the FLD terminal of the alternator.

Use a voltmeter, set to Ohms to test the diode. A good diode will show a high resistance reading in one direction
and a low resistance reading when the voltmeter leads are reversed.

Reconnect the diode to the FLD terminal of the alternator.

Use a voltmeter, set to Ohms to test the load resistor for a correct reading of 1/2 Ohm between pins 1 and 2.
