Starter Interrupt Relay
WARNING: This page is about a different car, the 2003 Ford Windstar and 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the starter interrupt relay from battery junction box. Check relay continuity. Continuity should exist between relay terminals No. 85 and 86, and between relay terminals No. 30 and 87a. See Fig 1. Continuity should not exist between relay terminals No. 30 and 87. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
- Using a jumper wire, apply battery voltage to relay terminal No. 85. Using a second jumper wire, ground relay terminal No. 86. Continuity should now exist between relay terminals No. 30 and 87. If continuity is not as specified, replace relay. If continuity is as specified, relay is okay at this time.
