SOURCE: Wiring diagram for the Harley Davidson 2007 FXDB

If you are gonna work on your own Harley, shell out the $60.00 for an H-D manual. They have a basic wiring diagram inside.

SOURCE: fuel pump?

the fuel pump for your 2000 fuel injected road king is located in the fuel tank. you will have to remove the speedometer housing, by first removing the seat, then remove the one small screw near the seat that holds the speedometer housing in place, also remove the small screw at the front of the speedometer housing and lift the housing off the tank and disconnect the wiring that goes to the back of the speedometer. there is a large oval shaped gold in appearance plate on top of the fuel tank. this plate is what the fuel pump is mounted to.

SOURCE: picture wiring diagram for 2003 harley fatboy

May I suggest a trip to your local library. Cycle repair books should be in 646 stacks of reference.
Otherwise you can Google for 2003 Clymer Service manuals on the internet.
I think Clymer had electrical diagrams in their books. I doubt that any except the HD service book would have anything about the physical location of the harness, but the pictures in the other books would help you.

SOURCE: 1974 Harley Davidson SPORTSTER TURN SIGNAL WIRING

I can help you with the wiring diagram but it will be the complete diagram. I have never seen just a turn signal only type wiring diagram. But, there's nothing to a '74 model Ironhead turn signal system.

All the wires for the system were gray but had these little "colored rubber bands" on the ends of the wires near the signal lights. The violet bands were for the left side and the brown bands were for the right side turn signals

Now, I cannot send the wiring diagram through this forum as it will not allow for an attachment. If you will contact me directly, I'll send you a wiring diagram as a jpeg attachment via e-mail. My address is wd4ity@bellsouth.net.

Good luck
Steve

I have 2008 GMC sierra 5.3 L with a new fuel pump. And no power to the pump. Any ideas where to look?


Fuel Pump Flow Control Module (FPCM) - LMF
The fuel pump flow control module (FPCM) is a serviceable GMLAN module. The FPCM receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The FPCM sends a 25 KHZ PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal. Maximum current supplied to the fuel pump is 15 amps. A liquid fuel pressure sensor provides fuel pressure feedback to the FPCM.
Electronic Returnless Fuel System (ERFS) - LMF
The electronic returnless fuel system is a microprocessor controlled fuel delivery system which transports fuel from the tank to the fuel rails. It functions as an electronic replacement for a traditional, mechanical fuel pressure regulator. A pressure vent valve within the fuel tank provides an added measure of fuel pump flow control module (FPCM). Desired fuel pressure is commanded by the engine control module (ECM), and transmitted to the FPCM via a GMLAN serial data message. A liquid fuel pressure sensor provides the feedback the FPCM requires for Closed Loop fuel pressure control.

The engine control module (ECM) sends the fuel enable signal to the fuel pump control module (FPCM). The control module monitors the voltage on the fuel pump relay control circuit. If the control module detects an incorrect voltage on the fuel pump relay control circuit, a fuel pump relay control DTC sets.

Fuel pump on VRSCA (2003 anniversary) doesn't work. Is this a common problem? Where to get exchange of the pump or the who,e assembly at a reasonable price?


Hi Herbert, I would check your system/fuel pump relay first it's only a $6 part. Then I would use 2 jumpers wires directly from the battery to the fuel pump to confirm function. If you need another pump I would recomend a new factory replacement or go on line and take your chances on E-BAY. For more information on your question please visit the websites below and good luck:
