Fix What?

What is the vehicle problem in detail ?

When did it start ?

What are you doing & have you tested,how &
the results ?

Nothing to test at the back of alternator, unless
your using an amp clamp & you can do that other
places, for the same results

Have you removed the alternator & had it tested at
parts store ?

Your using a Volt Meter I hope,not a test light
& an amp clamp as well

I have a draw on the battery on my 85 Toyota pickup it kills a fully charged battery in about 2 hours... Ive put a volt tester between the disconnected positive battery cable and the positive battery post...

Go to You Tube Video & see how to do a parasitic CURRENT
drain test

What you have done so far with a test light & volt meter is basically
doing nothing

You need an amp meter & a wiring diagram,then pull fuses one
at a time, to get to the circuit that causes the drain,then use the
prints to test that circuit for voltage drops

Hhr check charge system

Did they check the alternator too ? The warning light means the alternator is not charging the battery.

Battery light keeps staying on even though we have a fully charged battery and have replaced the alternator

Check to see what the voltage is at on on the large wire on the back side of the alternator. If its more than 14volts (with the car running) than put one test lead on that wire on the back of the alternator and the other test lead on the POSITIVE terminal of the battery. you should see less than .5 volts. If you see 12 volts or more than the wire from the alternator to the battery is open or has a lot of corrosion somewhere.

Can a Volage Reglator on a 2000 Chevrolet Lumina keep it from starting?

the voltage from the big red wire is battery power
the smaller wire will not have voltage until the alternator is running
one wire goes to the charge light to the voltage regulator
check that the voltage regulator is operational
better still get an accredited auto electrician to check the charge circuit , voltage regulator and alternator for operation

No charging voltage from alternator! i have 12v on the pink/blk wire with the switch on. I do not have battery voltage on the big red wire on the alternator either. traced that wire back to a battery...

you should have voltage on red when engine running? might be faulty inverter or altenator check connections or put a bulb tester on the altenator and see if it lights up ?????

Charge light stays on battery and alternater are good

If the red charging light is on, it generally means one of two things: either your alternator is not charging or your battery is too weak and is not charging properly. It also could be a wiring problem in the charging system. The method of testing the charging system is to use an inexpensive alternator tester that clips over the battery cable and indicates positive current. Some of the major auto parts stores have testers available for free loan and may help you with it if you desire to try to fix it yourself. The problem is that the alternator is expensive, so you will want to be sure what the exact problem is before spending money. Inexpensive current/charging testers are available to determine if your alternator's output is sufficient. This should be your first thing to do, which is to determine where the problem is and if its not the alternator, its probably a wiring problem and/or poor battery or corroded battery terminals. It's also possible that your system is charging but there is a current drain somewhere. An in-line current tester connected to the battery will determine if that is the case.

2000 Ford Taurus 6 cylinder with the alternate

i would check the fuel injector o # 5 cyl... if the injector is leaking it will foul the plug out and cause a skip. the next time it happens remove the plug and check for wetness. you may also be able to put a fuel pressure tester on, if so install the tester, turn the key on 2 or 3 times leaving the key in the on position at the end, do not crank the engine, watch the tester for a minute or so and watch for a pressure drop.
