How does a starter relay work on a solenoid?
In a starter solenoid, the magnetic force created by current flowing through the coil causes the core to move out. The moving plunger does two things. It closes contacts that switch on the starter motor. It also moves the pinion gear to engage the flywheel. As we can see, a starter relay only acts as a switch.
When does a solenoid need to be replaced?
Starter – Some solenoids are mounted to the starter, but some are located directly inside the starter housing. When this is the case, it may be necessary to replace the entire starter when the solenoid goes bad. Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient.
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.
What should I do if I have a bad starter relay?
They can also be hazardous and can cause damage. If you run into symptoms of a bad starter relay or solenoid with your car, truck, or SUV, make sure to have a trusted technician to diagnose the specific problem. This article is intended only as a general guidance document and relying on its material is at your sole risk.
How does a relay and solenoid work together?
Both a relay and a solenoid are devices that receive a low-power signal as a trigger to close (or sometimes open) a much larger circuit with more power. In the case of a starter, the ignition switch signals the relay/solenoid (possibly by way of a computer) and the relay/solenoid switches on the starter circuit to engage the starter.

Can a bad starter relay be a solenoid problem?
Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient. They can also be hazardous and can cause damage. If you run into symptoms of a bad starter relay or solenoid with your car, truck, or SUV, make sure to have a trusted technician to diagnose the specific problem.
How does a starter relay work in a car?
The relay is essentially a remote switch that controls a high-current circuit. In motor vehicles, a starter relay uses the small ignition switch current to close the much heavy-duty starter circuit. In some automotive applications, the starter relay works together with the starter solenoid to operate the starting system.
Why does my car say it has a bad starter solenoid?
Problems that might cause your car to act like it has a bad starter solenoid can include: Bad battery – If the battery voltage is low it will be unable to provide enough power to start your engine. Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem.
Where is the starter relay on a 1986 Softail?
Hello, all! Can someone please tell me where my bike’s starter relay is located? Some have said it’s back by the battery compartment, others have said it’s between the fuel tanks the only stuff I saw between the fuel tanks were mainly a bunch of wires…..my bike is a 1986 Heritage Softail (1340cc Evo).
Do you need to rebuild a starter relay?
If you check it with a voltmeter, it may show 12 volts, but the corrosion does not provide enough amperage to get through. Rebuild the solenoid. Do not buy a new starter. Once you have the starter off and the solenoid apart, you will see a copper washer and the contact from the + wire.
