NOTE:
The carburetor heater and accessory relays (if equipped with accessory relay) may be removed to isolate the
sound of the start relay click.
6.
If the reading is 12 VDC and the relay does not click when the key switch is turned to the START position,
replace the relay.
7.
If the reading is 12 VDC and the relay clicks when the key is in the START position, check the relay contacts.
7.1.
Set the multimeter to 200 ohms.
7.2.
Check for continuity between the 16-gauge red wire (w124) and the 16-gauge green wire (w128) start relay
terminals
7.3.
Monitor the multimeter. The multimeter should not indicate continuity with the key in the OFF or ON
positions. The multimeter should indicate continuity when the key is in the START position.
7.4.
If the multimeter does not indicate continuity while the key is in the START position and the relay clicks, the
contacts have failed. Replace the relay.

8.
If the reading obtained in step 5 is not 12 VDC with the key in the START position, perform the following test
procedures:
– Check battery.
See Test Procedure 1 – Battery on page 11-9.
– Check the 10-amp fuse (on w109).
See Test Procedure 2 – Fuse on page 11-12.
– Check the key switch.
See Test Procedure 5 – Key Switch (Starter Circuit) on page 11-15.
– Check the neutral switch on the transmission housing.
See Test Procedure 15 – Neutral Switch
– Check for continuity of the wire harness on wires w138, w110, and w43.
See Wiring Diagram on page 11-6.
TEST PROCEDURE 8 – Carburetor Heater Relay
See General Warnings, Section 1, Page 1-2.
