You can start a car without a battery if you hook up a jump pack or use jumper camples but it could fry your alternator. It is pointless to charge a car without a battery. When you charge the car you are charging the battery.
If the alternator is not charging the battery, then it will eventually go dead If the voltage regulator (in the alternator) is defective it will eventually kill the battery Check the alternator with a voltmeter A fully charged battery (without engine running) should read approx. 12.8 volts With engine running should read 13.8-14.2 volts
Probably need an alternator. Check your battery voltage with a multimeter, without the car running it should be around 12.5 volts with engine off. Start the car & check the battery voltage and if the alternator is charging properly it should be 13.5 or better at the battery. If not check the power terminal at the alternator itself and if only battery voltage (12 or so volts, same as battery) is there then the alternator is not charging.
To charge the battery on your 1998 BMW Z3 without disconnecting it, you can use a battery maintainer or charger with a clamp system. Simply connect the charger’s positive clamp to the positive terminal of the battery and the negative clamp to a suitable ground point on the car's chassis. Make sure the car is turned off and follow the charger’s instructions for proper charging. Always monitor the charging process to ensure safety.
Yes, it is possible to recharge a battery on an S type without disconnecting it, provided that the charging method is compatible and safe for the system. However, it's crucial to ensure that the charging process does not interfere with the vehicle's electrical systems or cause any damage. Always refer to the manufacturer's guidelines and instructions to avoid potential issues.
Kills alternator? don't you mean kills battery? Installing a new alternator without first charging the battery well (2amp for 8hrs) will quite likely burn up a new alternator as well as being hard on the battery.
You need to check your battery and alternator, to start with. If you're lucky it'll be something simple like those two. Sometimes you can get local auto parts stores to check them it for free. Typically that means that the alternator isn't charging. Many auto parts retailers will test the charging system at no cost. Their hope is that you'll buy the replacement parts from them. An automobile will run for a while after the alternator stops charging, but when an alternator is not replacing the electrical current the battery will eventually discharge and without recharging the battery SOMEHOW, with either a functioning alternator or an outside charger, the engine will eventually fail to start.
If you are careful and do not let the positive cable to the alternator come in contact with the motor or frame, nothing will happen. It is just a lot easier and safer to disconnect the positive cable from the battery. It saves possibly shorting out the cable and possible ruining the battery.
Alternator not charging battery sufficiently? Check with a voltmeter: A fully charged battery should read approx. 12.8 volts without engine running. With engine running should read approx. 13.8-14.2 volts
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
No, you must have a charged battery for the alternator to work.Here's an explanation of how the charging system works:http://www.ricksfreeautorepairadvice.com/repair-topics/alternator-generator/testing-an-alternator-without-blowing-it-sky-high
A clear sign is if your vehicle wont start without a boost, but fires up fine when boosted. Also dimming lights when vehicle is shut off or running, all signs you alternator is not charging your battery.
