The relay causes a 2 second delay between the first and any subsequent starting attempts allowing the flywheel ring gear to come to complete rest, preventing damage to the starter pinion and ring gear teeth.

When repairs are necessary, use the following wiring diagrams. The relay is available as a spare part, but the wiring harness is not available. if the harness becomes defective, repair it if practical, or if beyond repair, remove the re-start delay relay and harness, and connect the wiring as shown in the Electrical Troubleshooting Manual, page 113 model 124, page 105 model 126.

NOTE: Vehicles with non-repeat ignition feature can be identified by the relay (Figs. Fig 1 to 3).
