Pass The output current test passed. Go to Step 4.
Fail The output current test did not pass. Repair or replace the faulty wiring to pin 2. Go to
Machine to Service (page 21)
Step 4: Test the logic relay.
The enable relay is located under the left side cover. It is a 5-terminal relay with a 12-volt coil. See
1. 12 V Battery
2. Logic relay
1. Disconnect the wire harness connector from the relay.
2. Remove the relay from the mounting panel.
3. Check the relay and the harness connector for damage or corrosion and clean or repair as necessary.
4. Using a multimeter, verify that coil resistance between terminals 85 and 86 is from 71 to 88 ohms.
5. Verify infinite resistance (no continuity) exists between terminals 30 and 87.
6. Connect multimeter (ohms setting) leads to relay terminals 30 and 87. Ground terminal 86 and apply
+12 V to terminal 85. The relay should make and break continuity between terminals 30 and 87 as
+voltage is applied and removed from terminal 85.
