Testing the Glow Relay (continued)
Electrical System: Testing the Electrical Components
3. Check the coil resistance between the terminals 85 and 86 with a multimeter
(ohms setting).
Note: The resistance must be approximately 72 ohms.
4. Connect the multimeter (ohms setting) leads to the relay terminals 30 and
87. Then ground terminal 85 and apply +12 VDC to terminal 86. The relay
must break the continuity between the terminals 30 and 87 as +12 VDC is
set and removed from terminal 86.
5. Disconnect the voltage and leads from the relay terminals.
6. Connect the wire harness electrical connector to the glow relay after you
complete the testing.
7. Close the hood and secure it with the latches.
