Wiring diagram 1981 harley davison fxr

SOURCE: i need a wire diagram

The wiring is simple for a starter. You have a starter solenoid on the bike and a starter relay. When you press the button to start your bike, the button has a wire that runs to the relay. This triggers the coil in the relay and pulls the contacts in. You have three wires that run to the relay for the starter. One hot wire, a trigger wire from the starter button and a wire from the relay to the solenoid. When you press the button, the relay pulls in and makes the wire going to the solenoid "Hot".

The solenoid has three wires going to it. The large battery cable goes to the "long post" of the solenoid, There's another battery cable going to the starter from the bottom of the solenoid, The wire from the starter relay goes to the small terminal of the solenoid. The small wire from the starter relay is the trigger wire for the starter solenoid. When this wire goes hot, it magnetizes the solenoid and pulls the plunger inward. The plunger bridges two large contacts in the solenoid to put high current voltage to the starter.

If you need a schematic, contact me directly at [email protected]. I cannot send a file via this medium but I can direct e-mail. Remind me of what you need when you contact me.

Good Luck

I've got a schematic for a '91 model Softail. It'll probably be close enough to do what you need. Did you have a specific problem? If you'll e-mail me directly at [email protected], I'll send you a copy of the schematic. I cannot do it on this forum as the maximum size limit is 150Kb. Much too small. Contact me directly and I give you what I have. Remind me of what you need.

Contact me directly at [email protected] and I'll send you drawing. I need to know if the bike is a Big Twin or a Sportster.

contact me directly at [email protected] I think I have a wiring diagram that I'll send you. Don't forget to remind me of what you need and the year and model bike. I get a lot of requests and I can't remember who needs what.
