Relay, In-Rush Current Reduction: Description
In-rush Current Reduction relay is used on Engine Stop Start (ESS) equipped vehicles.
The In-Rush Current Reduction relay is intended to reduce the in-rush current drawn by the starter motor during the initial stage of the crank sequence, thus maintaining an adequate voltage level and allowing critical electrical systems to function without interruption, or reset. At the same time, the relay will allow sufficient current and voltage to reach the starter motor, to allow cranking the engine at an adequate speed, so that the engine can generate the air-fuel mixture necessary for self-sustained operation, even under adverse conditions.
This component is mounted to a bracket that mounts to the top of the starter assembly. The relay is serviceable and is shipped along with a bracket that secures the In-Rush Current Reduction relay.
