A.G.M. batteries do not give off any gas (hydrogen) when being charged, so there is less concern about ventilation when charging them. This allows them to be used safely inside a motorhome. … These batteries are also very resistant to vibration, due to their sandwich construction. Do I have toRead More →

For the three-phase motor, the stator winding has two connection methods: angular connection and star connection. High-voltage motors are generally star-shaped wiring, the purpose is to prevent motor windings from bearing higher voltage. … Why is a motor connected in Star? During starting the motor windings are connected in starRead More →

The voltage should read a minimum of 13 volts. A good alternator should put out between **13.5-14.5 volts. Stress test the alternator – Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on. WhatRead More →

Alternator whine is caused by a difference in electrical potential (voltage) between two points. It’s usually caused by a ground connection that is less than ideal. The main culprits are the amp, the head unit and any intermediate components such as crossovers and equalizers. How do I stop my alternatorRead More →
