About 2 seconds after key on, the asd relay shuts off it the computer doesn't see a crank sensor signal. So unless the engine is running or cranking the coil supply volts will turn off.
There's also the crankshaft position sensor mounted on the drivers side / top of the transmission housing. Some auto parts stores carry them, some don't. The voltage connector is on top of the intake manifold, near the firewall. Also check the voltage to the ignition coil.
Yes, the camshaft position is critical for both compression and ignition reference. That is valve timing. But there is no code to tell you your valve timing is off. There is a Camshaft Position Sensor, check for voltage at the connector, broken wiring or corrosion and then ohm out or replace the sensor. Get e repair manual and learn about your car, you'll save money, I promise...
there is a porcelain block on the firewall called a ballast resistor that limits voltage to the starter and there is also the voltage regulator that regulates voltage to the battery.
Of course it will
it should have the voltage regulator built into the alternator
Variable
A mercury battery will provide constant voltage. A voltage regulator circuit will also.
current.
The output impedance is z= V/I, the ratio of the constant voltage and the constant current source.
By installing the varialble resistor in the circuit,the constant dc voltage would change .
Voltage is not "used" Voltage is constant.
Constant voltage
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
12 volts
Crank Position Sensor
The engine computer is the voltage regulator in a 1997 Jeep Grand Cherokee.
