Early (A) and later (IN) main relay
1. The main relay is located on the left side of the engine compartment (photo).
Removing the EGI main relay
2. With the ignition on and using a voltmeter, check that there is battery voltage on terminals A, C and D (terminal B - earth).
EGI main relay terminals
3. To test the relay further, remove it and connect an ohmmeter between terminals A and B - the resistance should be approximately 70 ohms.
4. Connect ground to terminal B and apply 12 volts to terminal A.
5. Connect an ohmmeter between terminals C and D, and check that there is zero resistance between them.
6. Install the relay after checking it.
