What should the battery voltage be on a Porsche 911?
This will give the most accurate indication of the voltage in the battery. A normal battery should read a voltage slightly above 12 volts with the car sitting still, and no electrical devices on (the small trunk light in the front trunk shouldn’t make a difference in this reading).
What does it mean when your Porsche 911 is losing power?
This means that something is “on” inside the car at all times bleeding the battery of power. Start by disconnecting your battery ground, and connecting an ammeter to the battery negative and to the chassis.
What causes a Porsche 911 starter to overflow?
If the voltage is high at the battery (around 17 volts or higher), then the regulator is most likely faulty and needs to be replaced. Overcharging the battery at these higher levels will cause it to overflow and leak acid all over the inside of your car.
When does a Porsche 911 battery leak acid?
The battery will usually only leak acid if it has been overcharged at a much higher voltage. If the voltage measured at the battery is more than 16 or 17 volts, then the regulator is probably bad. If your battery has boiled over and has acid overflowing out the top, make sure that you clean up any spilled acid immediately.
What kind of battery does a Porsche 911 use?
Select your Year, Make, Model and Engine to find those that fit your vehicle. A high-performance sports car like your Porsche 911 is designed to give you everything you want in a vehicle, but even the most modern and technological of cars can’t function without a quality battery.
What should the battery drain be on a Porsche 996?
We normally say a drain of 0.25A is the upper limit and should give about 2 weeks life on a fully charged battery. Alternator voltage, measured at the battery, is normally between 13.25 and 14.5V, depending on health of alternator and associated wiring.
Why is my Porsche 911 alternator leaking acid?
If your battery appears to be leaking, then your voltage regulator has probably failed. The battery will usually only leak acid if it has been overcharged at a much higher voltage. If the voltage measured at the battery is more than 16 or 17 volts, then the regulator is probably bad.
What should the voltage be on a Porsche 911 alternator?
The next item to check is the voltage at the battery. This should read a little more than 12 volts with the engine off. When the car is running, the voltage should read at in the range of 13.5 to 14.5 volts with the engine at 2000 rpm.
