Notice: You can have an alternator dilemma With no "alt", "bat", or "gen" mild approaching.

I mounted my alternator by tapping on it flippantly with hammer. Fairly confident water had splashed as much as it from incredibly wet streets and the comb was stuck. Authentic problem was Demand Light-weight was on.

The only exception is When the alternator is OVERCHARGING: Basically putting out a lot of voltage. This may "DRIVE The pc Mad" when the engine is operating, and cause a variety of weird complications.!
In later diesel electrical locomotives and diesel electrical various units, the prime mover turns an alternator which supplies electrical energy for the traction motors (AC or DC).
Speaking of more recent stuff: More recent alternators have overrunning alternator pulleys on them. The alternator has the smallest pulley on the belt driven accessories, and it spins 4 or even more moments as more rapidly than another thing pushed from the belt. With an previous design strong pulley, if the engine promptly accelerates then decelerates (like in town driving) the smaller, promptly spinning alternator pulley places a large strain on the belt.
