Main Relay (Computer/Fuel System): Testing and Inspection

E.F.I. CIRCUIT OPENING RELAY ASSY
Continuity Inspection.
1. Using an ohmmeter, check that continuity exists between each terminal.

Specified condition:

Between terminals 1 and 2:..........................Continuity
Between terminals 3 and 5:..........................No continuity

2. Using an ohmmeter, check that continuity exists between terminals 3 and 5 when the battery voltage is applied across terminals 1 and 2.
