This is the regulator bypass hole

Chevy alternator hook up

Powermaster has technical bulletins that can help you determine the average amperage load of the accessories in your car, such as air conditioning, auxiliary lighting, high-powered stereos, etc. But if you do have a dash light that you want operable, they can tell you how to connect it, based on your particular vehicle.

This is the speed where the internal sensory circuit connects the battery voltage to the regulator, thereby turning the alternator on. Compact, but these alternators can provide big amps to power your electrical system with ease. The only thing you need to hook up on a one-wire alternator is a charge wire from the terminal on the alternator to the positive terminal on the battery or any positive battery source.

When I plug it into the light I need to know if the other connector goes to ground or hot pos. If you're trying to troubleshoot a battery that tends to go flat in a day or two for no apparent reason, try this method of troubleshooting.

In newer models, the alternator is internally regulated and can be connected with only one wire linked to the car's battery. Although these alternators are built into factory-style housings, they still look great under the hood - and only you will know that you have up to amps charging your battery.

This is the regulator bypass hole. If you do this while it's dark out and the main power wire is disconnected, the whole alternator will emit a cool X-Files type glow. For derby purposes it isn't needed so it can be either left off or jumped over to the main power wire.

When I plug it

It was also used in a lot of off-road equipment, so they're generally cheap and easy to find. You should never assume that the mounting bolts provide a clean ground, and therefore, a second ground wire should be used to provide a ground connection for the alternator. External voltage regulators are eliminated and built into the alternator itself.

It will have two wires coming from it. The external regulator can either be totally dismantled from the firewall or left in place. Although Mopar is in his blood, he loves any car that looks great and drives even faster.

The beauty of this is that it eliminates those extra, messy wires going to the external voltage regulator. The voltage regulator is internal, and there are no other wires that need to be connected to your electrical system. When you turn on the ignition switch, current flows thru the bulb to the alternator internally grounded and will light up the bulb.

Without a solid ground connection, the alternator may not charge properly. This can also produce a low voltage problem at engine idle speed depending on the amount of reduction.

That wire goes to a dash light. With many of these alternators, they are chrome or powdercoated, and that can compromise a good ground connection. Make sure it is a heavy gauge since it has to carry the full output of the alternator up to amps.
