Hall Effect Switch Test
NOTE:
Hall Effect switches cannot be checked with an ohmmeter like a pick-up coil.
- Disconnect 3-wire connector at Hall Effect switch. Connect a 12 volt battery and voltmeter to switch terminals. See Figure. Carefully note polarity markings.
- Insert knife blade straight down between magnet and Hall Effect switch. See Figure. Voltmeter should read within 0.5 volts of battery voltage. With knife blade removed, voltmeter should read between 0 and 0.5 volts.
