Look at it. If the wire is corroded and/or the insulation is bulging, replace the cable.

Jumper cables were hooked up wrong to my Chevy Malibu a 1980 I put a charger on the battery in the car and now it won't start. did i mess something up?
Probably. The alternator and voltage regulator may be fried, and the battery ruined. Take the battery to a battery shop and have them test it.
What is wrong is it seems like your battery is dead and the car will not start but the headlights still shine bright?
IT COULD BE YOUR BATTERY BUT I WOULD CLEAN AND CHECK THE BATTERY CABLES FOR A BAD CONNECTION. SOME AUTO PART STORES WILL TEST YOUR BATTERY FOR YOU FOR FREE. ALSO A GOOD WAY TO TEST IF IT COULD BE YOUR ALTERNATOR IS, IF YOU CAN BOOST IT TO GET IT STARTED THEN ALL YOU NEED TO DO IS REMOVE ONE OF THE CABLES WHILE IT IS RUNNING AND IF STAYS RUNNING THEN ALTERNATOR IS OK. THESE ARE THE MOST COMMON REASONS FOR YOUR PROBLEM. GOOD LUCK AND I HOPE I HELPED A LIL BIT. JEAN
When a car has two batteries how do you know which one is dead?
The only real accurate way to test any battery is to make sure it is fully charged, before testing. I have to assume you have a vehicle with two 12 volt battery's and a 12 volt ignition system? Make sure all connectors have been fully cleaned and checked for a good contact with all electrical components. Disconnect the ground on one battery and you can either load test the other battery..by using the vehicle starter or the headlights, to perform a load test. Then repeat the same test by disconnecting the negative cable on the other battery. Then connect the first one you disconnected. The key being cleanliness, fluid levels, Hydrometer test and load testing, as well as clean tight connections. And of course your charging system on your vehicle should increase to an estimate of 13.7 to 14 volts when charging. Good Luck. Buy a inexpensive volt meter from Discount store.
Can a battery charger also test a battery?
A battery charger can be used to test a battery if the charger includes a voltmeter, so you can read off the voltage. Note: A battery charger is designed to be used only for rechargeable batteries. It can be very dangerous to try to use a battery charger to test or recharge normal non-rechargeable batteries.
Why does car stop after jumper cable taken off?
If you car dies once your remove the jumper cables, it is most likely an alternator problem. Take your car to AutoZone or somewhere similar and they will test it for you. It could be that there is not enough charge in the battery to sustain the alternator. Try keeping the engine round 1500 revs while taking the jumper cables off.
What are the symptoms of a bad battery or cables?

Will a diesel engine run with battery cable disconnected if the alternator is bad?
A vehicle may not run if the battery cables are disconnected with or without a bad alternator. The best way to test an alternator is by voltage output when applying a load.

Test battery with a load tester. If battery passes you have a problem with connections or cables.
You changed your alternator and battery Starter was bad you believe but tested good Now car won't crank as if the battery is not strong enough What could be the problem?
Bad connectins at battery? Clean connections. Possible loose battery cables on starter or engine block? Clean and tighten cables. If no help, possible bad battery cable/cables. Test cables and replace as necessary. Depending on what type of car, also investigate starter cylinoid. Hope that helps.
Why will a 94 blazer with a new starter and battery not start just clunk noise..like wants to start but not enough juice to make it?
Try checking the battery cables and battery clamps to make sure you are getting a good connection to the starter. Do a voltage drop test to check the cables. You can find instructions for a drop test online.
Starter tapping when trying to start?
poor battery connection or battery itself high resistance in battery cables would be some things to check plus beanch test starter itself
After dropping gas tank remove fuel pump I jumpered to battery is that a good test?
It depends what you were testing.
How can tell if the battery is bad or the alternator?
Take the battery to a parts store so they can test it.... Actually you need to test both the battery and the alternator because if your alternator is not functioning correctly it can drain the battery of power... so just testing the battery may only tell you that you have a drained battery and not reveal the cause... This testing can be done using an Auto meter which tests the battery and also does an alternator load test...If you do not have a tester you can rent one from an auto parts store,or you can remove the alternator and take it to the auto parts store and have it bench tested along with the battery...usually for free...

What are the roles and responsibilities of testing and commissioning engineer in substation?
There are a great many. but to keep it simple: (a) pressure-testing the cables/switchgear/transformers/etc. (i.e. testing the insulation using high-voltage test sets); (b) testing the operation of the switchgear; (c) testing the operation of the protective relays. ...but lots more.
