I bought a starter relay cause has I'm driving my 1996 Chevy blazer s10 and going over railroad tracks and up hills my blazer stales out and won't crank but when I sat for a while it starts back up and I have a new fuel pump but ever since I had it on my blazer it doesn't make that that sound when the key is on position
My car has an automatic transmission.its got a brand new oil filter,module,everything that I can think of that can cause the car not work right or stale.but if anyone can till me where the stater relay is I be greatfuly aprecated .been try to figure out what's
Hello, and thank you for writing in. The starter relay is located in the main fuse box under your hood. On the back of the fuse box lid will be a diagram which will tell you what relay you want to swap out. You may also want to look into the charging system (the battery, alternator, and wires) to make sure it is working properly. Makes use the battery cables and it’s ground connection are all clean, dry, and tight. If the problem is not solved by then, check into your fuse box and ignition switch. The best way to determine what is at fault is to recreate the issue at home. For more help resolving the issue, contact our service department to schedule an appointment.

Starting relay position
In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed. It is also called a fuse box. This box is usually installed on the driver`s side of the vehicle.
Most of the time you`ll be able to find your starter between the transmission and the engine, below the left bank of engine cylinders on the driver`s side. Cars with a rear-wheel drive, however, tend to have their starter located on the passenger`s side of the engine, just below the exhaust manifold.
Relays are normally used in the control panels, manufacturing, and building automation to control the power along with switching the smaller current values in a control circuit.
The starter relay not only completes the electrical circuit, but it also boosts the battery`s current. If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won`t turn over – no matter how many times you turn the key.
The starter solenoid is above the starter motor. The threaded terminal at left would connect to the battery through a heavy cable. At the right end of the solenoid coil, a linkage inside the housing would engage the pinion visible in the housing at the right side of the motor.
Starter relays may look different across brands and vehicle types. However, they operate the same way and perform a similar function. Looking inside these components, you will realize that they have identical parts. A typical starter relay consists of housing, coil windings, magnetic core, and an armature or plunger.
Because it contains moving parts, the starter relay itself can also fail over time. If it fails, the ignition makes no sound when the ignition key is turned. There are two types of starter relays: internal starter relays and external starter relays. Internal starter relays are built within a starter motor.
Many relays, if installed for the wrong application, could and will cause a short (Internal Relay Circuit) and most likely cause functionality issues or even damage to the vehicle computer systems.
As the magnetic field of a relay coil collapses when the coil is de-energized, a high voltage spike can occur. The diode prevents the electronics that are connected to the coil from absorbing the spike. But if you connect them backwards, you can end up with a short circuit.
Between the vehicle`s battery and the starter motor, a starter relay serves as an electrical circuit completer or circuit breaker. It assists in increasing the battery`s current so that less current is required upon ignition.
Once the Starter Interrupt has been installed the optional override allows the vehicle to start once disabled. To override the starter disable you need to turn the key to the crank position for 3 seconds, then turn the key to the off position for 3 seconds. Repeat this 2 more times and the vehicle will start.
Incorrectly wiring a starter will have a huge impact on how well it performs. “Bigger displacement requires you to rethink things, just like with fuel delivery, valvetrain parts, and so on. The starter got bigger and the output grew, so the wire must get bigger too.
Basically, as long as the solenoid can handle the amperage, it should work.
A Starter relay requires about 8 volts to “pull” in the contactor core. Once engaged it will stay engaged until the voltage drops to about 3 volts.
There are 2 types of 4 pin relay available; normally open or normally closed. A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated.
Why won`t my car start but the battery is good? If your car won`t start but the battery is good, the most common cause is a faulty starter – though it could also be to do with your fuel. You may have insufficient fuel to get the car going.
How a Starter Disable Relay works to disable the starter of a vehicle with one wire. The controller interacts with the relay by grounding its output to the relay to disable the starter (open circuit output to starter).
Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that won`t start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.
Rusting, power failure, irregular pressure, missing equipment, an incorrect amount of voltage or current, dirt stuck in the system and corrosion are some of the possible reasons why a solenoid valve may not properly close or open.
When a solenoid is first energized, its coil receives a pulse of high inrush current that decreases as the plunger closes. If the plunger does not close, the high inrush current continues, which can cause the coil to overheat and burn out. This is the most common cause of solenoid failure and spotting it is easy.
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Burnt out coils cannot be repaired and will need to be replaced.
The starting relay is a small electrical device located in the starting circuit of a large current motor. The relay is just a remote control switch that regulates the current in a high-current circuit.
PTC relay is a specific starting device, which works for the compressor of the refrigerators. The principle function of the PTC relay is to provide power to the start winding for a brief period to help to trigger the motor of the cooling compressor.
Set your multimeter to be on the Ohms scale. Place one probe on the lead on the ignition circuit terminal and the other on the ground lead. The reading should be less than 5 Ohms. If it`s more than that, the starter relay is faulty and needs to be replaced.
