Testing
1. Remove the diode from the harness connection.
2. Use a volt / ohm meter set to the ohm or diode
setting to test the diode.
3. Measure the diode resistance, record the value.
4. Reverse the ohm meter leads on the diode terminals
and measure the diode resistance again, record this
value.
- If the resistance value is the same in steps 3
and 4, the diode is shorted or open – replace the
diode.
Note: If the yback diode tests shorted or open,
also test the PTO clutch as shown in this
chapter.
- A properly functioning diode will be open in one
direction and have an ohms resistance value
when the meter leads are reversed as shown:
