A starter motor solenoid is a critical component of your car's starting system. It's responsible for converting electrical energy into mechanical energy, or in other words, it's what makes your starter motor turn and start your engine. But how do you know when something is wrong? If the solenoid is on its way out, you may end up stranded by the side of the road, so it pays to know some more about this diminutive but important part.
I've been running an auto service shop for the past 30 years. The trends in cars have changed a lot over that time, and cars are becoming a lot more complicated and automated. People can't fix many items on their own cars any more as you need a computer to diagnose most issues. People use their cars a lot more these days as we live further away from workplaces and schools so it's important for me to be able to get cars back quickly. I have had to keep learning about how the new cars run and I keep a lot of hints on this site so you can all learn the things you can do to make your cars run better.
