Where are the relays on a starter motor?
Internal starter relays are built within a starter motor. The relay is the switch mounted on the outside of the starter motor housing with its own case. Most of the time, when a starter motor fails, it is usually the starter motor relay and not the armature or gear that goes bad. External starter relays are separate from the starter motor.
What to do if your starter relay is blown?
Locate the starter relay circuit fuse and verify that the fuse is in good condition. If the fuse is blown, replace the fuse, but do not attempt to start the vehicle without checking the condition of the starting circuits. Step 3: Look at the battery and check the post connections.
Is the starter solenoid bigger than the starter motor?
The starter solenoid, on the other handed, closes the switch for the starter motor and usually mounts on the motor. It is usually bigger than the starter relay and of heavier construction. This guide contains information about the automotive starter relay.
Why does my car starter make a clicking noise?
Insufficiently charged batteries, corroded connections, and damaged battery cables can all prevent the starter relay from receiving enough power to operate correctly. When this happens, an audible clicking noise is typically heard when the ignition key is turned. Because it contains moving parts, the starter relay itself can also fail over time.
Can a bad ignition switch cause a starter relay to fail?
