Why is my car battery 17 volts?

Why is my car battery 17 volts?

It may be that the regulator is packing up and the alternator is going to max. unregulated output because of a bad battery output voltage (alternator input) connection between the battery and the alternator.

Why is my battery 19 volts?

Probably your regulator internal in your alternator,causing your battery to overcharge,deffinately can overcharge to 19 volts, if your battery is being overcharged look for your battery becoming warped and smelling. Could do with testing the voltage when driving see how the voltage changes.

Why is my battery at 16 volts?

A simple problem of loose wires and connections can cause your battery voltage to fluctuate. You may think it is flat, charge it and afterwards voltage can go as high as 15V or 16V.

Is the alternator charging at 18 volts or 23?

Alternator charging at 18 volts, replaced alt and didn’t fix. Have read some other answers on similar problems, blue wire reads 18 volts, green wire reads.23 volts? have the same problem?

What should the battery voltage be when the car is running?

The voltage, when the engine is running, should be in the range of 13.5-14.7 volts. When your car is running the cars alternator is charging the battery, this is why you should see a higher voltage. If you’re readings are significantly higher or lower than these then it would indicate a fault with the battery and/or the alternator.

What do I need to charge my Kawasaki lawn mower?

So you need to trace and check each component/connection in the charging system from a good starting point. Bear in mind also that the system ground needs to be a good connection. This is usually done at one of the engine mounting bolts along with the battery negative cable and other grounding connections.

What does it mean when battery voltage is 12.2v?

Measuring the voltage shortly after the engine has been running can give you a higher, misleading, reading. If the voltage is below 12.6v it indicates that the battery isnt fully charged or has a fault. The voltage doesn’t have to differ much from 12.6v for it to indicate a discharged battery. At 12.2v the battery is in effect 50% discharged.

Why is my alternator putting out 17 volts?

Why is my alternator putting out 17 volts? It may be that the regulator is packing up and the alternator is going to max. unregulated output because of a bad battery output voltage (alternator input) connection between the battery and the alternator.

What’s the correct voltage for a fully charged battery?

The rule of thumb that states 12.6 volts equals a fully charged battery and 12.2 volts means it is 25 percent charged, is starting to change with some modern batteries and charging systems. If there is a dead or weak cell, normal charging voltage can’t be achieved on a battery with a bad cell.

What should I do if my lawn mower battery does not charge?

If your lawn mower battery does charge fully, the charge should not drain if it is not in use. Troubleshoot continued problems by using a multimeter ( service part number 19602) to see if your battery drains power while not in use. If it holds the charge through testing, you may have an issue with the alternator.
