Hi Randynsue, you have a dead short which is usually the easiest to find. Using a test light connected to the hot side of the blown fuse holder, start probing the wire leaving the fuse holder about an inch away the test light should illuminate, keep probing towards the ignition switch until the test light no longer illuminates you are now very close to the short. For more information about your issue, please visit the websites below, and for specific information or questions, please feel free to contact me at xlch@mail.com. Good luck and have a nice day.

Horn doesn't blow wont crank when ignition turned on a 2003 dyna superglide


Harley horns fail. Replace the horn. If this fault has happened at the same time as engine wont crank then problem with wiring. If not then check starter relay (grey one). Also check ignition switch. Are the head lights coming on when turned on? If so the ignition switch is o/k. Connect a voltmeter to horn to check horn circuit. Accessory fuse 15 Amp supplies horn circuit and brake light and turn signal circuits so if these are working fuse o/k. Ignition/start circuit requires system relay and ECM fuse to be o/k. If fuel pump operates when run switch is activated then system relay o/k. Check start relay and circuit to start button.

2002 FLHTCUI diagnostic codes


I went to a more trouble than I usually do to answer this because it is a frequent question. In general, a halfway decent HD service department will plug in their Scanalyzer, tell you what the trouble code is and what it means and reset the ECM at no charge. If they want to charge you for doing this, then find another dealer. My daughter is a board certified physician and she makes less than half of what these blood suckers charge per hour.

Make sure the ignition is off. Locate the Data Link plug. Identify pins 1 & 2. Use a female spade connector to short out pins 1 & 2. Turn the ignition switch to on. Engine check light comes on for 8 seconds. After that, the check light will count off the trouble code. If you have resolved the problem associated with the trouble code, then the solid check engine light after ignition on will shut off after 50 - 100 starts, depending upon the model year of the ECM installed on your bike.

Good luck.

My 05 Harley electra glide wont start or light up


Hi Nicoleelizab, when checking for spark the CKP needs to measure the compression bump in order to send the correct signal to the ICM/ECM so always check for spark with either a third plug grounded or lift the end of the plug boot 1/2 " off one of spark plugs that are in the head. and the usual suspects are:
1. Fuel tank empty
2. Fuel supply valve turned off.
3. Fouled spark plugs.
4. Engine flooded with gasoline as a result of over use of enrichner.
5. Fuel valve or filter clogged.
6. Vacuum hose to automatic fuel supply valve disconnected, leaking, or pinched.
7. Discharged battery, loose or broken battery connections.
8. Loose wire connection at coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, spark plug cable connections loose,
or cables connected to wrong cylinders.
10. Ignition timing incorrect due to faulty ignition coil, ignition module, or sensors " Manifold Absolute Pressure" "Camshaft Position Sensor" "Crank Position Sensor" "Brake Apply Sensor
11. Engine lubricant to heavy ( winter operation )
12. Sticking or damaged valves or push rod wrong length.
13. Primary cam sproket spline sheared or missing spacer.
14. Security alarm system not disarming.

most often these problems are solved by mending the wires going in and out of headlight or faring assembly. They can get worn or pinched during service, or bulb replacement etc.

Head light & spot lights quit working.


Check if there's (live + (positive) current coming to the headlight and the spot light once you turn them 'on' .
If theres no live (current) there thn the switch could be faulty, remove the switch and you can also check over there the live (current) to the input terminal of the switch and after tht operate the switch and check if theres current passing thro to the required wire for the head light and the spot light.
If theres no current to the switch thn you have to trace it back to the fuse box and finally to the battery .
Hope this helps.

Blows ignition fuse when key is turned on


Look for a grounded wire on the ignition switch or a break in the wiring leading to the fuse. Wiring system on motorcycles are a close system with only the battery being grounded to the frame. Any loose connections or breaks in the wires that will allow the current to jump to the frame with cause you tons of fun.
