Hi, Debbie if your headlight is not working, intermittent, only one beam works at a time, keeps burning out, blinking, dim or surges from bright to dim to bright the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your headlight bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to the headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chafed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/low beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator/lighting coil
11. Faulty voltage regulator/rectifier ground or overcharging.

SOURCE: I have a 1990 sportster 1200. I changed the handle

The wires got pinched under the seat frame or towards the Handel bars.Under the seat there are relays .Take the seat off and turn the ignition on and inspect the relay , which ever is making the clicking noise.Also inspect the head light and tail light wiring, may be any of them getting loose or flickered, due to this its flashing.----------If the breakers are not resetting, maybe you still have a grounded wire? The breakers are located under the seat to the rear. Also, have you checked the cut-off switch on the right handlebar? Maybe that wire is open or grounded(or the switch is off--it happens).---------- ----------- But if all checked ok, then this clicking noise which you hear is shorting starter relay.This relay is located under the seat.Its not a costly relay, and easy to replace an easily available at local auto part store.------ Replacing this relay should help.----------- Thanks.Helpmech.

My harkey davidson soft tail fat boy 2004 does not want to start but if i put on jumper cables it starts if i take it off it dies

The battery on your fatboy is certainly dead and needs a replacement, if the issue is with the wiring it wouldn't have started anyways so the battery is the culpri.

I'm replacing a tail light assembly and wiring

Usually it connects under the seat somewhere and the wires run under the fender in a trough.

good luck
