How does the starter work on a Porsche 911?

Another problem area for starting is the starter, of course. The starter is a somewhat complex device for what would seem to be a simple task. There is a solenoid on the starter that both actuates the small gear that turns the flywheel and switches on the main starter motor.

What are the wires in a classic car starter relay?

Classic car starter relays will often have four wires in the connector. With the ignition key in the on position, there should be power on the heavy gauge red wire and a strong ground on the black wire.

Why does my 911 have trouble turning over the starter motor?

When 911s have trouble turning over the starter motor, it is often because there isn’t enough current to fully trigger the solenoid on the starter. This can be caused by a number of reasons. The most common reason is old wiring in the car.

How to bypass ignition switch for starter solenoid?

This is what I did to bypass the ignition switch for the starter solenoid, and just run the relay coil from the ignition switch. I made 3 12″ long jumpers. Then I had to check to see which side of the relay the Ignition switch was on. The opposite side would be connected to the starter solenoid. I connected the jumpers to the relay.

Why does my starter not engage with the flywheel?

You can hear the starter spinning, but it’s not engaging with the flywheel. What could be wrong? The most common causes why your starter won’t engage with the flywheel is low battery voltage, a faulty starter solenoid, faulty starter motor, and wiring problems.

What should I know before jumping the starter solenoid?

This is the most important thing to check before thinking about jumping the starter solenoid. You need to make sure that your car battery can supply enough current to start the solenoid and turn your engine. Even if your vehicle has a bad starter solenoid, you need a good and strong battery to start the engine.

Why does my car not start when I Turn on the ignition?

In the case of broken wires, electrical current from your battery will not reach the starter. If the wires are in place and still your car will not start, then you must replace the starter solenoid. The obvious symptom is when your vehicle fails to start when you turn on the ignition. An electrical signal should go to the starter relay.

What happens when you push the start button on a car?

When you turn the key or push the Start button, the engine should start and the circuit that controls the starter motor should close. If the starter remains ON even if the engine is already running, then this might mean that the main contacts of the starter solenoid are welded together in the closed position.

What are the causes of ignition fuses blowing?

What Are the Causes of Ignition Fuses Blowing? Fuses are current overload protection devices, specifically engineered to act as the weak link in an electrical circuit. A fuse keeps a circuit from passing excess current and destroying whatever’s attached to it or melting the wires and starting a fire.

Why are the fuses blowing on my computer?

Inspect your wires carefully; hot parts on the engine can easily burn through the wiring’s insulation and short the wires, and metal edges will cut through the wires and short them out. If you’ve got fuel injection, then you might be experiencing an internal short in the computer itself.

How does a fuse work in a car?

Fuses come in all types and varieties, but they all work in a similar fashion. Current passes through the fuse via a small metal strip or a spring; that small metal strip creates a sort of bottleneck in the system, a point of high impedance where electricity will slow down and turn into heat.

Is there a remote starter for my car?
