Question about Toyota Land Cruiser
I want to replace an externally regulated alternator with an internally regulated alternator. How do I do the wiring?
Usually the alternators possess one thick white colored wire directly coming out of the battery positive terminal (+) which is around 8 mm (outer diameter) and connects the battery with alternator and white or black 3 wires connector which is inserted at the rear of the alternator. If you look carefully at the rear of the alternator you will find the embossed letters there. Some time the letter may vary depending upon model year of the vehicle. Normally the letters describe L= Alternator warning LAMP in the in the instrument panel of the speedometer. B= 12 Volts coming out of the ignition switch on the ON position. G= Ground or chassis ground.

If you ask for a one wire delco alternator,all you have to do is connect the large wire on back of the alternator to the positive battery post on the battery.The alternator is self energizing,there for no problem with wiring up a harness.If I can help,let me know my name is Ron.>>>firstname.lastname@example.org

I am assuming you are now using a 1976 style GM alt.
The most common and popular model.
You need one 10 gauge wire from the battery to the alternator output.
This can be run directly from the battery +.
Run a short 10 gauge wire from alt output to large wire at regulator plug on alt.
Run small wire on alt reg plug to Bat light wire.
A new alt regulator plug pigtail can be bought at any parts store and is recommended.
The existing regulator should have the connections marked.
One of those wires will be the bat light wire if needed.
If you have a amp meter or voltmeter in the vehicle.....use your existing large output wire (usually red) to hook up to the new alt output connection.
