What else can I help you with?
What can cause the diode in the alternator to fail in a fiat punto?
Just like anything else things just break. Have you had any electric welding done on the car? Have you used an external battery charger? Have you accidently connected the battery in reverse polarity?
Can bad diodes in the alternator cause the battery to go dead when the car is off?
Bad diodes in the alternator can cause the battery to go dead when the car is off. The diode bridge (six diodes) is directly connected to the battery, and is used to convert three phase delta AC from the alternator's stator to DC for the battery. Normally, if the engine is not running, the diodes are reverse biased and do not conduct current. If one of the high side diodes is shorted then the diode trio (another set of three diodes supplying the regulator/rotor) could conduct and drain the battery. Often, a diode failure is a short or an open. A short in a high side diode along with a short in a low side diode would result in high current from the battery, and that would probably blow the fusible link. An open would result in poor performance of the alternator.
Which color, red or black, should be connected first when jumping a car battery?
When jumping a car battery, the red positive cable should be connected first.
Which color should be connected first when installing a new battery in a car: red or black?
When installing a new battery in a car, the red color should be connected first.
You Connected the battery to wrong terminal corrected but car is not running right why?
You cross the battery.
Can a battery be charged while remaining connected to the car battery cables?
Yes. A battery can be charged while in the vehicle.
How does hybrid car recharge battery?
The alternator is connected to a gas powered engine. This charges the battery.
How do you keep a battery good if car is sitting?
Purchase a trickle charger and keep it connected to the battery.
When charging a car battery, which color goes on first?
When charging a car battery, the red positive cable should be connected first.
How do you charge a deep cycle battery with a car?
You don't. This would put a strain on the alternator and may burn a diode out. Charge it with a deep cycle battery charger.
Is a car battery a cell?
No. Strictly speaking you get a battery when you have several cells together. The typical car battery consists of 6 lead-acid cells connected in series.
Can you drive a car with the battery in backwards?
As long as the cables are connected properly.
