There is a pretty good set of diagrams here:

You need to register, but everything is free. I recommend you do some testing to narrow it down to the circuit before getting into the wiring diagrams.

Please see my tip at . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Let me know if you need more help.

Battery light stays on and drains battery. Brand new battery, alternator and starter?

What is year--make--model?
If something wrong with wiring circuit, somewhere, replacing the part won't fix it.
Make sure charging system is working properly. To look up wiring diagram, I need vehicle info. The battery lite is on even with key out? Unplug alternator, see if light stays on, check the alternator wiring connector.

1997 grand prix wiring diagram

disconnect the earth wire from the battery and install an amp meter in the circuit . This will give you an idea of the current draw that flattens batteries . Next remove the battery wire from the alternator ( Carefully as it is a live wire ) and hold it away and read the amp meter. If the current is close to none then remove and repair the alternator as you have a faulty diode in the plate

Ford f150 4.2 not charging put in new alt and batt

Fully charge your battery. Some years of Ford F150 had parts which would interrupt any battery drain to preserve the battery. This would include the charging circuit which was see as parasitic.

The Antitheft would also cause problems in the electric circuit.

The newer Alternators are not made to work as well as the old ones. If the new Alternators have to work too hard they will fail from overheating so a bad battery could cause the Alternator to never catch up.

Also go to for a free wiring and fusebox diagram when you register your truck online. Check if there is a inline fuse within the first 30" from the Alternator. Or check for a charging Relauy in the Powerbox diagram.

My car battery keeps getting drained, i changed the alternator twice we checked the fuses as well, the alternator is fine and fuses our fine the battery is new but is drained, please help

You need to put an AMP Meter in series with either battery cable, and then look for a circuit not timing out,after you remove the key.
May take 20 minutes.
Anything over 40 Milli-Amps is too much
Start pulling fuses one at a time, to find circuit, then you need a wiring schematic of complete vehicle to find problem.

I always purchase shop manuals and wire diagrams, as soon as I buy a new vehicle. Will need owners manual -for fuses.
