Divide your alternator pulley size into your crank pulley size to get the ratio. Example: If you have a 6quot; crank pulley and a 2quot; alternator pulley. 6/2=3. You have a 3 to one ratio, you multiply your engine RPM by 3 so if your engine is turning 1500 RPM#39;s your alternator is turning 4500 RPM#39;s. Note: you do not count the diameter of the other. The car would charge normally till you blipped the throttle, then the pulley would stop driving the alternator. You could look into the alternator and see that the internal parts were not spinning, with the engine was running. The quot;in the carquot; metalnerd tool wouldn't work on the aftermarket pulley/alternator so I had to pull the damned thing.

The alternator belt also known as the serpentine belt passes through several pulleys on the engine. When the crank turns, the belt pulls the other pulleys and causes them to spin, including the alternator pulley. Naturally, the friction caused by spinning through so many pulleys at high speeds will eventually wear the belt out. It can also be caused by a blown fuse or bad wirings. If your serpentine belt snapped off, the alternator will, of course not charge then either. Now when you know the most common reasons, you probably want to know them in detail also. Here is a list of the 5 most common reasons why your alternator is not charging the battery. Answer 1 of 4: Pretty freely. Even new the bearings will spin with little effort.

It's usually the electrical section/ voltage regula.

Jan 01, 2006 Pulley is free spinning. I put a 24mm wrench on the nut and then I hit the wrench at the other end very fast with something light. This quick impact amazingly tightened the nut enough that the alternator quot;axlequot; no longer spins on the pulley. Now when I hold the pulley in place in a wise, I can torque it as normal. I torqued it to 50-60 lb-ft.

Loops of wire armature windings are wound on a special laminated holder called the ARMATURE. The armature is turned by placing a pulley on one end of the shaft and driving it with a V-belt from the engine#39;s crankshaft, as seen in the figure.

Anyways as I#x27;m doing this I decided to check the alternator pulley I had done so previously and thought it was fine and actually noticed that it didn#x27;t spin as smoothly as I originally thought. It#x27;ll spin easy for maybe a 1/2 to 2 rotations and then it#x27;ll have some resistance and repeat.

The alternator is an apparatus that manufactures electricity to power the ignition system. Your alternator transfers engine power to 12-volt electrical energy and transfers it to the battery.

I understand that it should lock up one way, and spin the other if I put a stick/rod/screwdriver in the alternator to stop it from spinning. Mine locks up one way and spins the other, but it doesn#39;t spin as easily as my idler pulley or tensioner pulley.

An automotive alternator is a type of generator which creates Alternating Current AC. A belt from the vehicles engine spins a pulley which is connected to the rotor of the alternator. On the shaft are either permanent magnets or copper wire coils with a small DC current flowing through them. The flow of current creates a magnetic field.
