No, a defective battery will prevent the engine from starting but once it is running the battery will not cause hesitation. the the starter relay is disengaged , and the alternator takes over battery charging via voltage regulator . voltage regulator prevents power surges and prevents voltage fluctuation.
A bad voltage regulator can cause an overcharging condition. Check the wires going to the regulator for corrosion and make sure the regulator has a good ground.
Defective voltage regulator.
No, the voltage regulator determines the alternators output voltage. That's all it does. If the regulator fails the battery level can drop to the point that there will not be sufficient charge to start the engine, but the regulator will not directly cause the engine to not run.
* Voltage Regulator * Defective Battery * Dirty Battery Post Connections * Alternator/Generator problems
Bad voltage regulator
no, the voltage regulater is for charging not the ignition system, it can however drain the battery
Some possible clues: * Alternator/Generator not putting out enough voltage to properly charge system * Voltage regulator problems * Weak battery, or one that's about to give out totally
defective voltage regulator
the voltage regulator
A voltage regulator is just as it says. It regulates the voltage that the alternator in your vehicle puts out. Too much voltage and you'll overamp your wiring, and too little can cause parts not to function properly.
