A hard start relay basically directs the electrical current from the battery, through the relay and to the starter motor instead of routing it through the ignition switch. This eliminates a path of approximately 15′ of wiring and potentially bad connections. Once installed, your ignition key simply activates the relay.
Full Answer
How does a mechanical potential relay hard start kit work?
With the help of electro-motive force, the mechanical potential relay hard start kit takes the capacitor out of the circuit once the compressor is at 80% of its capacity. Most technicians find this kit more reliable thus it is often the recommended type.
What is a hard start and how does it work?
What is a hard start? A hard start is where the inrush of current is spiked to reduce the time taken to get a system started up. You can use a hard start when your electrical current needs a boost to get the motor starter. The inrush of current is heightened which can put your motor at risk of overheating or suffering a shorter lifespan.
Why install a hard start relay on a vintage VW?
There are numerous reasons why you may want to install a hard start relay on your vintage VW. A hard start relay basically directs the electrical current from the battery, through the relay and to the starter motor instead of routing it through the ignition switch.

How do I test a hard start relay?
Disconnect the voltage source from the circuit and remove the relay from the circuit. First check the relay's coil by placing the leads of the ohmmeter across the 2 and 5 terminals of the relay. If the ohmmeter reads a high resistance (approximately 3,000 to 18,000 ohms) the coil of the relay is electrically OK.
What is a hard start on a refrigerator?
A starter device is commonly referred to as a refrigerator hard-start kit. Hard-start kits come in several varieties, but the best choice for the do-it-yourselfer is the 3-in-1 kit which combines the compressor's overload relay, start relay and starting capacitor.
How do I know if my starter relay is blown?
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. A faulty relay often produces an audible clicking sound when you turn your car.
Can a hard start kit damage a compressor?
While using a hard start kit can prolong the life of your air conditioning, it can also cause some possible damage to the compressor with continued usage. The reason is due to the fact that a hard start kit will send too much current for too long to start the compressor.
When should you use a hard start capacitor?
A hard start kit is an energy-storing capacitor that helps your AC start when it's struggling to turn on. As their name suggests, hard start kits help solve a problem called hard starting, which is when an AC struggles to turn on and then shuts off abruptly after a short while.
Is a hard start kit necessary?
Anyone who owns an air conditioner should get a hard start kit because using them will allow the compressor to start up in as little time as possible in the inrush amperage mode. The quick startup will extend the life of your AC units compressor and allow the unit to start more efficiently.
What's considered a hard start?
A hard start is where the inrush of current is spiked to reduce the time taken to get a system started up.

Is a starter relay and ignition relay the same thing?
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. Now the terms relay and solenoid are often used interchangeably and there is a lot of confusion about which is which.
Can a bad relay cause a car not to start?
Car not starting: Another symptom of a faulty ignition relay is a no power condition. If the relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition.
Why do you need to take a start capacitor out of a circuit?
While a run capacitor has heat dissipation capability for constant duty, a start capacitor MUST be taken out of the circuit VERY quickly to avoid melting down and causing compressor damage. The start capacitor is REMOVED from the circuit by a relay called the potential relay. The potential relay is normally closed, ...
Is it bad to wire between start and run?
Some hard start manufacturers wire the coil on the potential between start and common, and some wire it between start and run. You will find that most OEMs wire between start and common, but this does not mean that wiring between start and run is bad; it just needs to be designed correctly for that purpose (Kickstart does it this way).
Can you use hard starts with a relay?
Use hard starts with REAL potential relays, not timers, solid-state, or other relay types (in my experience). Size the relay and capacitor according to the manufacturer's specs. Ensure that you have a good quality, properly sized run capacitor on any system with a hard start. For a complete write-up on potential relays, ...

How to tell if starter relay is bad?
If you try starting your car and there’s no sign of starting or even a click, and your interior lights are bright, it may be an indication of a bad starter relay.
What does the starter relay do when you turn on the ignition switch?
When you turn on your ignition switch, it sends an electrical current to the starter relay, which transfers the current to the starter solenoid. The solenoid sends the power to the starter motor, which rotates the flexplate to start the engine.
Why does my starter motor click but no crank?
This is also a sign of low or dead battery. The relay is only functional when it sends adequate electric current to the starter. Less or high power could either damage the entire starter system or won’t start the vehicle, accompanied by an annoying clicking sound.

Hard starters are most helpful when it comes to large AC units within residential or commercial buildings.
What is a soft start motor?
Soft starters are best used when the power source is a small generator .
How does a soft starter work?
A soft starter works by controlling the amount of voltage running through the circuits of a motor. The soft starter can do this by affecting the torque of a motor, which reduces the voltage and allows it to manipulate the voltage to allow for a smooth startup and acceleration.
Why are hard starters and soft starters important?
Hard starters and soft starters are extremely valuable in protecting your motor and applications from the uncontrollable inrush of current that is created when you start up your motor. They can both be used to protect the motor and appliances to an extent, but both do this in very different ways.
What is the efficiency of a soft starter?
Soft starters tend to have an efficiency of 99% or higher . Soft starters can protect the motor and circuits from the initial inrush of power, extending the lifespan of these components. Soft starters can protect against overheating.
When should I install a soft starter?
A soft starter should be installed when you need to control the torque and starting current during starting and stopping a motor. Once the motor is running, the speed will be constant until it’s turned off. Soft starters leave you with a simple, economical solution for your motor.

Why is my air conditioner hard to start?
Worn down compressor motor due to loss of lubrication is another cause of hard starting. Without proper or enough lubrication, the compressor tightens up and has difficulty moving. Hard starting may also be a sign that the air conditioner is worn down and ready for replacement.
What is a hard start kit for air conditioning?
A hard start kit does two important things for the air conditioning compressor: It reduces the electricity used to power up the air conditioning system. It reduces the startup period of the compressor. Without a start capacitor, it takes the compressor four to eight times more electric current to start than to keep running.
