This procedure covers the removal and replacement of a generic electrical relay on the 1970 AMC Rebel Machine, applicable to most relay types in the vehicle's electrical system.

Warnings

Tools required

Parts

• Replacement relay × 1 — Match original relay type and amperage rating

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition to OFF position and remove key
3. Disconnect negative battery cable to prevent electrical shorts
4. Locate the specific relay requiring replacement (common locations include firewall, fender well, under dash, or near component being controlled)

Procedure

1. 1

   Identify and access relay
   Using a flashlight, locate the target relay. On the 1970 Rebel Machine, relays may be mounted on the firewall near the master cylinder, on the inner fender wells, or under the dashboard. If a relay cover or access panel is present, remove it by hand or with appropriate fasteners.
2. 2

   Verify relay identification
   Before removal, verify you have identified the correct relay. Note the relay position, wire colors, and any identifying markings. Take a photo if possible for reference during reinstallation. Check that the replacement relay matches the original in terminal configuration and amperage rating.
3. 3

   Disconnect relay wiring
   If the relay uses individual spade terminals, carefully pull each wire connector straight off the relay terminals, noting their positions. If using a multi-pin connector, release any locking tab and pull the connector straight off the relay. Do not pull on wires; grasp connectors only.
4. 4

   Remove relay from mounting
   If relay is held by a mounting bracket or clip, carefully release the retaining mechanism. Some relays simply plug into a socket and pull straight out. Others may have a mounting screw or bolt requiring removal. For bracket-mounted relays, remove the fastener and slide relay from bracket.
5. 5

   Inspect terminals and connections
   Examine the relay socket or wire terminals for corrosion, heat damage, or looseness. Clean any corroded terminals with electrical contact cleaner and allow to dry. Inspect wiring for damaged insulation or burned connections. Address any wiring issues before installing new relay.
6. 6

   Install new relay
   Position the new relay in the mounting location, ensuring proper orientation. If using a plug-in socket, align pins and press firmly until fully seated. If bracket-mounted, secure with original fastener. Ensure relay is firmly mounted and will not vibrate loose.
7. 7

   Connect relay terminals
   Reconnect wiring to relay terminals in the exact configuration noted during removal. For individual spade terminals, press each connector firmly onto its terminal until it clicks or seats completely. For multi-pin connectors, align and press connector onto relay until locking tab engages. Apply light dielectric grease to terminals if working in moisture-prone area.
8. 8

   Reinstall covers and reconnect battery
   Replace any access panels or relay covers removed during the procedure. Reconnect the negative battery cable and tighten securely. Reset clock and radio as needed.

Reassembly

1. Ensure all wiring connections are secure and properly routed away from heat sources and moving parts
2. Verify relay mounting is secure and relay cannot move or vibrate

Verification

• Turn ignition to ON position and verify that the system controlled by the relay functions properly
• If relay controls a cooling fan, horn, fuel pump, or other component, test that component operates correctly
• Listen for relay clicking when circuit is activated, indicating proper operation
• Check for any unusual smells, smoke, or heat from relay area during initial operation
