what can csuse a starter motor to continue to run after engine starts 1988 ford f-150

Before we discuss the starter solenoid problems and bad starter solenoid symptoms, allow'southward figure out what is a starter solenoid first.

A starter solenoid is a major component of an automotive starter arrangement. It helps in starting the engine by performing 2 functions:

i. Acting as a switch to deliver a high current from the battery to the starter motor.

2. Using the electromagnetic force created when current flows through its windings to produce a mechanical move. The movement drives the pinion, engaging it to the ring gear of the engine'southward flywheel.

The starter solenoid is, therefore, an of import component of an engine's starter arrangement.

It has to function well for a car to kickoff.

But it sometimes becomes faulty, and any endeavor to showtime the engine becomes unsuccessful.

At that place are 4 about mutual starter solenoid issues.

iv Mutual Starter Solenoid Problems

#1.The starter solenoid failing to reset, even upon releasing the starter push button, or turn the car switch in the off position, the starter continues to operate.

#2.The sucking activeness of the starter solenoid failing from time to time.

#3.The drive gear failing to restore in fourth dimension, leading to it existence driven by the flywheel ring gear reversely. This problem results from a return spring that has become too weak from repeated use.

#four.The starter solenoid failing to work up the starter to cause rotation. It only makes a serial of sounds without starting the engine.

What Causes a Starter Solenoid to Become Faulty?

Reasons for a bad starter solenoid vary. Some causes act singly and others in combination. They include the post-obit.

Bad Wiring

Poor and hurried wiring lead to either inadequate current supply to the starter solenoid or a more dangerous trouble of shorting. Both can make a starter solenoid to malfunction and crusade starter system bug. Bad wiring instances include terminals that are left loose or connected the wrong way.

Excessive Heating

It happens when extremely loftier currents flow to or through the solenoid, and for likewise long.

It can exist caused by instances where the ignition switch is left in the 'showtime' position for long.

The soldering in the contacts melts, and they weld together.

When that happens, the starter solenoid becomes damaged because you can no longer command its switching part.

Excessive Moisture

If moisture is left to get inside the starter solenoid, it leads to corrosion of the electric contacts.

The issue is reduced electrical conductivity of the contact surfaces.

The efficiency the starter solenoid becomes greatly reduced, and yous feel occasional starter fails.

You may hear the starter click and then stop nearly immediately when the current proves too low for the whole operation to finish.

Too Much Tightening of Bolts And Other Fasteners

It'due south commonly very like shooting fish in a barrel to over tighten bolts without being enlightened of it.

It happens particularly if you're using tightening tools with a high torque, which causes some parts inside and outside of the starter solenoid to break or bend.

It tin lead to shorting or mechanical failure of the afflicted parts.

The starter solenoid is just ane of the components of a starter system.

While a problem with starting the engine may be every bit a issue of it existence damaged, it's not always the case, and learning how to diagnose a faulty i is important.

So, how practise you tell that it's your automobile's starter solenoid that's bad? Hither are indicators to assist you in ascertaining that.

Symptoms of a Bad Starter Solenoid

A starter solenoid that'southward faulty exhibits various symptoms. Some of them are straightforward while others require keenness to observe. Ofttimes, a bad starter solenoid will accept the following signs.

#1: A serial of rapid or successive clicks coming from the starter solenoid

It indicates a situation where the holding coil of the solenoid keeps holding dorsum, mostly as a result of not enough current reaching the solenoid.

Information technology tin can exist acquired by loose connections or corroded terminals. Information technology can as well be a sign of contacts that have welded together, or that take get worn out. It means the solenoid's efficiency has been compromised and it isn't operating strong enough to produce the required force to cause mechanical movements.

#2: The starter continues to rotate fifty-fifty afterward the drive gear disengages and start push has been released from the 'on' position

This is a symptom of burnt out contacts. Information technology results from the contacts being exposed to high currents and rut over time causing the surfaces to melt and fuse together. If left unattended to, information technology can lead to more damage to the whole starter system by subjecting it to unceasing and dangerously high electric current.

#three: The starter solenoid makes a clicking sound and moves a little, just the starter does not rotate

Information technology could exist a result of a starter solenoid that's broken or a defective solenoid-starter connection. Or it can be a example of decreased electrical conductivity due to corrosion, dirt, and breakages.

#4: The starter continues to rotate after the kickoff button has been released, but the bulldoze-gear doesn't reverse

Information technology indicates burnt out contacts that remain closed even after the ignition switch is taken back to the 'off' position.

Information technology can also hateful an immovable return spring due to lost elasticity from repeated use.

What to practice if a starter solenoid appears to be bad

Some minor faults like loose terminals tin can be remedied by making simple repairs.

Major damages, peculiarly the ones involving the within of a starter solenoid may warrant its total replacement.
Before making final diagnoses that your starter solenoid is the one causing starter failures or whatever other problem with starting the automobile, you would demand to exam information technology. Often, this is done with the help of a multimeter to decide if the starter solenoid is working the right way.

The possibility of the bombardment be the crusade of the starter fault should also be ruled out.
Information technology can be done past testing the battery itself, or by ensuring the 1 you're using is in fantabulous condition. If in doubt, you can even supplant the existing battery with a new one, especially if the current one has been at that place for too long.
