Those wires are to put the electronics into diagnostic mode. They are to be disconnected for normal use.

How do I replace my regulator on my 2001 FXDWG

The Voltage regulator, or rectifier, is located at the front of the engine between the two front down tubes of the frame, near to where the oil filter is. It looks like a block of metal with heat sink fins on it and two long wires coming out of it.

To remove the part, first disconnect both the negative and positive leads at the battery. The smaller wire from the positive side of the battery is one of the two wires attached to the voltage regulator. Next, remove the two bolts holding the regulator in place at the front of the bike. Trace the two wires coming from the regulator to where the first one attaches to the battery and to where the other attaches to a two or three prong connector under the bike near the back of the primary.

Disconnect the prong connector and pull both it and the battery wires out from the front of the motorcycle, noting their routing as you will need to route the new wires in the same way during installation. Remove the regulator and wires from the bike.

Install in reverse order, reconnect battery, start engine and test for voltage at the battery terminals with a voltage meter. Should read around 14 volts.

Engine stops while driving in rain as if fuel has gone to reserve. Has to be started again. It happens very frequenty

A can of WD40 might help you locate the problem, I think your plug wire or coil might be effected by moisture. this is WD40 is all about WD stands for WD 40 = water disbursement, get a small spray can and carry it with you if it happens again spray the plug and wire and coil with it and see if this helps, you can also pre treat before you go and see if it stops the problem ? I think you have a bad boot,wire or spark plug, you can also seal these wire boots with some silicone like the stuff you use on a valve cover gasket . see the guys at your local automotive parts store and ask them for help.. tell em Jay the pool pump motor repair guy from Florida sent ya .. hope I was of help get back to me if I was .. thanks Jay

I have a yamaha 50cc scooter where is the battery located

Some bikes don't have a battery. It sounds like the bike you have is a small single cylinder dirt bike. If this is so, then you probably have a magneto that powers the ignition.
Trace the spark plug wire from the plug to the other end. The other end is where the magneto is located.

I have a 2004 K1200GT and have unfortunately misplaced my manual in a cross-country move. I thought I remember being told there was a 12V plug-in somewhere on the bike ( where one might run..say a GPS unit...

Yes, there is a 12 V accy. socket on your bike which can be used to charge the battery while it is still in the bike or for powering 12 V gadgets. If memory serves the socket is located on the LHS of the bike.

GPS consume very little power, so you could wire it directly to the battery with a small (3-5A) fuse in the line. Battery is located directly under the seat.

Hi there,

Well you can please follow the below steps -
1. First of all gather all of the documents you will need for the installation, including the alarm system instructions and wiring diagrams. You can get wiring diagrams from the dealership (or from BMW site), from your motorcycle's original manual or online. Know the wiring colors, locations and polarities before you start.
2. Plan the installation to save time in the long run. Examine your motorcycle side-by-side with the diagrams. 
3. Get all of the necessary equipment together. The type of equipment you'll need will depend on the system you buy. 
4. Prepare the wiring. Find the motorcycle's battery, and disconnect the negative (-) terminal to avoid electrical shorts and battery drain.
5. Twist the wires of the same plug together and tape them with electrical tape. Once you finish wrapping these smaller bundles, tape them all together. Find the wires you will be connecting to on your bike.
6. Locate any additional wiring. Most of the wires will be running from the ignition of your motorcycle back toward the center of motorcycle to the fuse box. Open the ignition switch to test the wires to make sure they are the right ones. You will not be connecting to a wire near the ignition. You will need to follow the wire back towards the fuse box, closer to the mounted alarm system.
7. Remove the panels where your wires are located. Remember where all the screws and clips go.
8. Pick a location for installation. Find a spot that is not visible. 
9. Strap or adhere the system to a support brace or flat surface. If you use the adhesive pad that came with the system, make sure to prepare the surface with rubbing alcohol or a degreaser before mounting.
10. Test wire polarity first and then start connecting the wires to the correct locations. The best way to do this is by soldering or heat-shrinking the connections. You can also splice the wires and then tape them with electrical tape.
11. Know the wires. The ACC/Interface wire connects to the IGN/ACC wire located in the motorcycle's ignition switch harness. The wire you are looking for in the ignition switch harness should be 12 volts when the ignition is on, and should not show any voltage when the ignition switch is off. 
12. Find the engine immobilizer wires. Cut the side of the wire that leads back to the main power of the bike. Connect one end of the cut wire to the first immobilizer wire and the other end of the cut wire to the second immobilizer wire. 
13. Connect the power and ground wires directly to the battery terminals. You will need wrap-around clamps or terminals taps. 
14. Refer to the manual and make sure all of the system's functions are working properly. If you have any problems, read the troubleshooting section of the manual and check all of your connections.
15. Put all of the panels back on. Hope it helps........

Good Luck!!

Lost key

Hi there,
Here are a few methods of how to do this, please read carefully!
Method 1
  1. Open the hood.
  2. Locate the red coil wire. Both the plug and coil wires are located at the rear of almost all V-8 engines. Four-cylinder engines have them placed on the right side, near the center of the engine. Six-cylinder engines are the opposite: left side, near the center of the engine .
  3. Locate the battery (it's the thing that looks like a battery).
  4. Run a wire from the positive side of the battery (not negative!) to either the positive side of the coil, or the red wire that leads to the coil. This will give power to the dashboard, which is essential if you ever want it to start.
  5. Locate the starter solenoid. On Fords, it is on the passenger-side fender well, near the battery. On GMs, it is on the starter under the steering wheel.
  6. If under the steering wheel, enter the car without setting off any alarms. If it has standard transmission, make sure the car is in neutral and the parking brake is on.
  7. Unlock the steering wheel by taking a flat blade screwdriver and placing it at the top center of the steering column. Push the screwdriver between the wheel and the column, then push the locking pin away from the wheel. Don't worry, you're allowed to be rough here. The locking pin will not break or set off any alarms. The solenoid should be underneath.
  8. You will see a small wire at the top of the solenoid and the positive battery cable below. Cross the two different terminal that they are connected to with a screwdriver or pliers. This will crank the engine, giving you leave to drive. Congratulations.

Method 2
  1. Enter car. Do not break into a car unless you own it and have documentation to prove it. Be aware that forced entry will set an intrusion alarm off if the vehicle is so equipped.
  2. Determine if the steering column and gear selector can be overridden, if so equipped. Serious damage to the shifting mechanism and/or steering column will result in forcing these theft deterrant mechanisms in an attempt to override them.
  3. Look under steering wheel. This may require taking an access cover off. These are usually held in place with concealed clips or #2 Phillips type screws. Remove if needed.
  4. See if there is a clip or wiring harness connector in which you can gain access to the wires behind the ignition.
  5. Look for the two wires that are the same, usually red and strip them and twist them together. One of these will be the primary power supply for the ignition switch, the other will be the connection for the vehicles electrical circuits that are energised when the key is turn to the run position. Connecting these will provide electricity for the ignition components, so the engine is able to run when the starter is turned.
  6. Strip about 1 inch of insulation from this pair of wires, and twist them tightly together. Wrap with electrician's tape if available, and do not allow them to short against metal vehicle components.
  7. Get the ignition wire, brown in many cars, strip it about 1/2 inch, and touch the end of the stripped brown wire with the connected red wires.
  8. Do not twist the brown wire to the reds, just touch the wires until ignition has been achieved.
  9. Rev the engine enough so you don't stall and have to do this process again.

Method 3 This is the most effective method due to the fact that you don't need to bother keeping wires together, raising the hood, or unlocking the steering wheel. If you hotwire it with the wires only, your steering wheel WILL NOT TURN unless you break the steering lock. The "classic screwdriver method" where you put a screwdriver in the lock and twist doesn't work because you can't generate enough torque with your bare hands to make the lock pins break off without breaking the lock off of its mounting structure, thereby rendering the car useless. Use this method instead.
  1. Gather materials: 1 flathead screwdriver with an insulated handle, 1 cordless drill and a small drill bit.
  2. Take it from an expert: So, there is a flap at the end of the keyhole. Position the drill on the keyhole about 2/3 of the way up and drill in about the length of a key. This will destroy your lock pins and make the key switch able to be turned on and off without a key. Every pin has 2 sections, followed by a spring, so drill it more than once, removing the drill each time to allow the bits of the lock inside to fall into place.
  3. Put the screwdriver in the same way you would put your key in, it doesn't have to go in deep because the pins are already broken.
  4. Use it the same way you use your key, just turn it.
    • Warning: this method will destroy your key switch and make it so anyone with a screwdriver or an exceptionally strong fingernail to steal your car.
  • Use this knowledge responsibly.
  • Vehicles with a computer chip in the ignition switch cannot be hot wired, the chip enables the ECM to function, and without it, the car will not run.
  • You risk causing significant damage to your vehicle if you hotwire it.
  • Never leave the ignition wires twisted together when you finish running the engine. This can burn up the ignition system of the vehicle, and will at least discharge the battery.

  • If the ignition wires separate while driving, the engine will instantly die, and you may find yourself without power, steering, or brakes.
  • Don't use this in an illegal manner, such as to steal a car. Chances are you'll be caught, and prison is not a fun place.
Thank you for using FixYa! Have a nice day and please remember to rate this solution.

Warm regards,
