“I’ve had lots of trucks, cars, boats, motorcycles, and antique cars all my life. I recently had a truck with a power loss problem. I took it to two good mechanics I used for years, and couldn’t find answers to the problem in a three week period. Took it to Jerry and three days later the truck was running great. Very, very thorough.

Here are some in depth explanations of large electrical components you may like.

The starter turns stored DC electrical power from the battery into rotational motion that cranks your engine until the first fuel charge fires and the engine turns on it’s own. If you would like an in depth look into the working of the starter motor I found this old but good video.

How A Starter Works

The Battery stores electrical energy when the car isn’t running. Flooded lead acid batteries are the most common, but some special applications use an Absorbed glass mat type of battery. You can learn about batteries at this site.

Lead Acid Battery

The alternator is turned by the running engine and creates the electrical energy the car uses to run the car and all of it’s accessories, it is also tasked with maintaining the batteries chemistry and capacity. Here is a good video explanation of how an alternator works.
