What happens when battery voltage is increased?
What happens when battery voltage is increased? If resistance (I.e., the load) is constant, then the voltage and current will alway be proportional to each other. So if the voltage is increased, the current will also increase, rather than drop as the Question states. Think of it as water flowing through a garden hose. What should the battery voltage be at cruising rpm? If voltage is over 14.2 under maximum loads when at cruising RPM, buying a bigger alternator or a new alternator is a waste of time and money. Turn the motor off with no load (headlights, etc. all...
