To bypass the alternator exciter wire, first disconnect the battery cables and remove the negative cable. Then locate the exciter wire on your alternator and unplug it from its connection point. Next you will need to create a jumper lead that is connected between two points on the alternator, typically either two spade connections or one spade connection and ground (a metal part of the engine).
Once this is done, reconnect your battery cables and start up your vehicle’s engine. If all goes well then you have successfully bypassed your alternator’s exciter wire!
- Step 1: Locate the alternator’s exciter wire
- This wire will run from the main power source to the alternator and is normally located near the battery terminal
- Step 2: Disconnect this wire from both ends, cutting it at least 12 inches away from either end
- Step 3: Insert a resistor in place of where your exciter wire was connected on one of its ends
- Make sure that the resistance values match what was previously used for your original exciter wire so that current flows correctly through the circuit
- Step 4: Connect a separate piece of wiring in between each end of your resistor and reconnect them back to their respective terminals
- Make sure all connections are firmly secured before testing out your system again
Tricks to Get Alternator Working
If your car’s alternator stops working, the battery will eventually die and you’ll be left without power. Fortunately, there are some simple tricks you can try to get it running again. Firstly, check all the cables connected to your alternator for any loose connections or corrosion that may have caused a disruption in the electrical current flow.
Additionally, cleaning off any dirt or debris near the alternator can help free up space for better airflow and help prevent overheating. Finally, if necessary, replacing worn-out parts on your alternator such as brushes or bushings can improve its performance significantly and get it back up and running again!

Will an Alternator Work Without an Exciter Wire?
The alternator is one of the most important components in a vehicle as it provides power for all its electrical systems, including the starter motor. An alternator requires an exciter wire to work properly, as this sends electricity from the battery to activate the alternator’s internal regulator. Without the exciter wire, no current can flow into the regulator and thus no output voltage will be produced by the alternator to power other parts of your car.
In short, an alternator cannot function without an exciter wire since it needs that initial boost of energy in order to start generating electricity on its own. If you’re experiencing issues with your vehicle such as dim headlights or difficulty starting due to lack of electrical power, then checking whether there is a problem with your exciter wire may be worth considering before replacing any other parts.
How Do You Manually Excite an Alternator?
Manually exciting an alternator is a simple process that requires only basic tools. The most important tool for this job is a multimeter, as it will be used to measure the current being produced by the alternator. To begin, disconnect the battery from the vehicle and connect the positive lead of your multimeter to one of the posts on the alternator.
Then attach a wire with alligator clips at both ends to each remaining post on either side of the alternator; these are referred to as field terminals. Connect one end of this wire to ground and then touch 12 volts (from another 12V power source) onto its other terminal while monitoring your multimeter’s reading. If you have done everything correctly, you should see an increase in amperage on your display indicating that you have successfully manually excited your alternator!
After verifying proper operation, don’t forget to reconnect your battery before driving away so that it can provide any additional charging necessary for powering accessories or recharging batteries if needed!
Does a 1 Wire Alternator Need an Exciter Wire?
A 1 wire alternator is a type of alternator that typically requires only one wire to connect the battery, ignition and regulator. This makes it much easier to install and maintain than traditional two-wire systems. However, some 1 wire alternators do require an exciter wire in order for them to work properly.
An exciter wire provides extra current which helps the alternator start producing power more quickly when the engine starts up. It also helps keep the voltage output from dropping too low while the vehicle is running at an idle speed or stopped in traffic. If you are installing a 1 wire alternator on your vehicle, make sure to check whether or not it needs an exciter wire before beginning installation so that you don’t have any problems later down the road.
Which Wire is the Exciter Wire on Alternator?
The exciter wire on an alternator is the wire that provides power to the rotor field coils. This power causes current to be generated in the stator, thus creating a magnetic field which, in turn, causes voltage to be induced into the armature windings. The exact location of this wire will vary depending on make and model of vehicle but generally it can be found connected directly to one side of the regulator or spliced into a harness near where it connects with either side of the unit.
In most applications there will also be an additional diode placed between this lead and ground for protection purposes. It is important to note that if you are replacing an existing alternator with a new one then you may need to transfer over any parts such as resistors or diodes from your old unit as these components can’t be purchased separately from many manufacturers.
