    battery/alternator problems

    I have a 1997 caters cadi. Car wouldn't start one day so I ended up changing the battery. Nothing happend. So I ended up changing the alternator. It work and drove around for a little bit. Then again stopped working. I have no clue at this point what this might be causing or whats making my battery drain. If someone knows what this is please respond to this. Thank you.

    Is the battery voltage low?

    Does the engine crank and not start, or not crank at all?

    Re: battery/alternator problems

    You have to give more than, "Then again stopped working." This car ain't no '64 Chevy with a 2 barrel and breaker-points ignition.

    When the trouble started did it crank and not catch or just sit there dead?

    Any change at all with the new battery? Did it start and run the car but eventually drain?

    The new/rebuilt alternator put out a charge? What voltage?

    What shape are the battery cables in? Is the insulation cracked and chunking off? Are the terminal ends corroded?

    Re: battery/alternator problems

    An inexpensive digital voltage tester can tell a lot about the charging system on a car. If the battery is dead, jump start it and drive it for a good 30 minutes to give the battery a good charge before you do anything.

    With the red probe connected to the positive terminal and the black probe connected to the negative, look at what the battery voltage is at rest. It should be around 12.5 volts. Start the car and see what what the
    voltage is at idle, it should be between 13.7 and 14.3 volts. Turn on the lights and the rear defroster and see what the voltage drops to. It should only drop 1/2 a volt, or so. if it drops more than that, you should
    check the battery posts and cable connectors. If that is OK, than you probably have a bad cable going from the alternator to the battery.

    I had low charging problems last fall and I got a new set of brushes for the alternator and still had the problem. I took an old jumper cable and used one side of it and bought a couple of heavy duty connectors and
    made my own cable. Attached it from the positive output on the alternator and the other end to the positive on the battery and haven;'t had a problem in 5 months.

    Re: battery/alternator problems

    What kind of replacement alternator did you get and where did you get it? I can tell you from experience that there is a lot of junk being sold as "rebuilt alternators" these days. Look at the voltmeter on the dash. The alternator should be charging at at least 13.5 volts, preferably 14.
