This extra resistance wire does not affect the functionality of the indicator light in any way. It will light if the alternator stops charging then? Don't forget to reinstall the dust cap. Regulators What exactly does that little black box on your inner fender do? Since the alternator is turning, you also have battery voltage on the exciter wire from the alternator. Whether this line runs to the Bat terminal, junction box or starter, it should include a fusible link to protect your alternator from a short circuit. If that is the case then Ijust hook it to the positive side of the light, and the negative just goes to ground, correct? You connect the output of the alternator back to this terminal so that it can sense and regulate the output voltage.

A standard diode rated 1. Yes, if the bulb burns out, no charging results, same for resistor. In addition, many of the vehicles that use the 1-wire conversion tend to be specialty use vehicles and thus do get stored for a long time between uses, so the battery drain could be an issue. This voltage back feeds to the entire ignition system. Many times the Coil Wire and the Alternator Exciter wire are connected to the same terminal on the ignition switch.

Rob All cars are different. Run a wire with a fusible link from the big post on the rear of the alternator to the battery or big post on the starter. Good luck It's nice to see this brought back. This is how the battery gets charged when the engine is running. The preferred way is like you discribe but I run it right off the bat term on the alt. Every modern vehicle uses an alternator - and for good reasons.

When guys are updating their electrical systems in their cars, they have lots of choices. On an alternator, a magnetic field is spun inside of windings of wire called a stator to generate the electricity. So I did install it correctly. The resistor method is very cheap subject to type and quality , very easy to wire with no polarity issues, and reliable. There are two smaller terminals, usually spade terminals on the top of the alternator.

Install the dust cap over the two spade connectors on the new regulator. This is one of the best places to find information about parts, rebuilding, restoration and racing. The purpose of the diode is, a check valve for electricity, this will prevent the alt from back charging the ignition system. Trade marks and trade names used for reference purpose only. It should always be relayed.

. Some later-model and aftermarket replacement regulators are solid-state devices that are quieter and longer lasting even though they look pretty much the same externally as a mechanical unit. The ones I personally installed worked fine as well as when I used a resistor. The difference that results from this can be very noticeable, especially in cars with the battery mounted somewhere besides the engine compartment. See the instructions that came with your 3-wire alternator. In the truck you can hook it up to the battery terminal on the alternator but you are better off hooking it up to the junction box if you use one or the starter, becuase that'll give the alternator a more accurate reading on volts.

This alternator has the advantages of high output, compact design and ease of use. In my case, my rebuilt puts out 80amps at high rpm. If all goes well, the light never comes on, and you drive happily around knowing all is well with your alternator. When you turn the key on but have not started the car yet, the field acts as a ground and power flows through the light and out to ground - lighting the bulb so you know it works. Usually, this is a direct connection from the alternator output back to the sense terminal. During normal operation the lamp stays off.

Its an internal regulater alternator. This lack of moving parts makes the alternator not only very reliable - but also comparatively inexpensive to build and repair. The alternator will attempt to keep 14. The alternator will then attempt to maintain 14. For all generators and externally regulated alternators, the regulator is a small device mounted somewhere on the firewall or the inner fender of the car. The diode is a one way device that passes current in one direction and blocks it in the reverse direction.
