With the key on and the bike running , the bike will some times shut off. All power is lost as if the key were turned off.If i play with the key the lights all come back on and the bike starts no problem.....

It sounds like you have a dirty or broken contact base on your ignition switch. Unfortunately, you do not have a replaceable contact base on your switch. Your best option would be to replace the ignition switch. You will end up with two keys for your cycle but it will fix your problem. The only other option is to carefully disassemble your switch and attempt to clean the contact points in the switch. Worst case scenario would be you break the switch and have to replace it anyway. Happy trails.

My 2003 sportster died out suddenly 4 times in 3 miles the other day the same thing happened 4 years ago and it was the ignition module so i think it is the module again is there anyway i can...

There is a test procedure in a service manual but they specify that you must use a particular type of multi-meter to make the test or your results will vary. I've never successfully tested an ignition ignition unit. I've always replaced a "known bad" unit with an aftermarket unit since I was an independent mechanic. The dealer may have a way to test the unit. But, if your problem is intermittant, if they test it and it's working, they won't find a problem. If it ain't broke, they can't find a problem. Catching the problem when "it's there" could be a problem. It's strange that you've had to replace the ignition system once and think you might have to again on a 2003 model. I've got a 1994 Wide Glide that still has the original ignition system on it and I've seen some bikes with as many as 75K miles on them with the original ignition system. Harley's ignition system is a pretty good unit. Have you checked your fuel petcock and the gas cap vent? Harley went to a vacuum operated petcock in 1996 and they do give problems. Your bike has a full tank of fuel but none in the carburetor. The tank vents through the cap and if it is blocked, vacuum builds up in the tank. Try loosening, but not removing, the gas cap so air can get inside the tank. If that cures the problem, replace the cap.

Good Luck

Motorcycle Mechanic Advice on a 1992 Heritage softail. Having ignition problems. Lights come on and I get a clicking in the starter relay, but when I switch it to ignition, there it is completly dead....

I'm a little confused. You said that the lights come on and you get a clicking at the starter relay. Then you say that when you switch to igniton, everything goes dead. From the factory, you must first turn the switch to the ignition position before you can get anything, lights, starter, horn. Some guys set their switches up to be like an old style bike. First click is ignition, second click is ignition and lights. But, since most states now require you ride with your headlight on all the time, Harley simply wires the switch to a "one position" switch.

At first guess, I'd think you have a bad switch because you said the when you went to the "ignition" position, everything went dead.

But, you said that you could get lights and a clicking noise. If the clicking is coming from the small one inch plastic cube starter relay, you may or may not be getting power to the starter solenoid.

Look at the starter from the right side of the bike and you'll see a five sided plate with three small bolts holding on. At the top of this plate, you'll see a single wire connector. Unplug this wire and use either a test light or a volt meter to test for voltage on this wire when you press the start button and the starter relay clicks. If you do, the relay is good but something is wrong in the starter. If no voltage, the relay is not doing it's job.

Good Luck

No brake light at all, changed bulb still nothing, wiring is all good,running light works, all other lights work,just no brake light at all..

There are two switchs that operate the brake light. One is a mechanical switch at the handlebar brake lever and the other is a pressure operated switch somewhere along the metal rear brake line.

To test the brake light wiring, find the pressure switch on the rear brake line. It should have two electrical connections on it. With the ignition switch on, jumper across these two connections. The brake light should work. If not, there is something wrong with either the wiring, the socket, or the bulb. If it works, I'd replace the pressure switch. They aren't expensive.

If the front brake switch doesn't work, you can replace the switch in it but you'll have to remove the switch housing on that side of the handlebar, unplug the wires for the switch, swap out the switch with a new one, plug the wires to it, and replace the switch housing. Sounds simple and really it is but not as easy as it sounds. You'll have to deal with the throttle cables and mechanism as well. Good Luck.

No response from the ignition switch

If there still is no response to your ignition switch once that you already have check the fuse in the starter solenoid of your bike then you have to service the ignition system. but if you can't then you have to go to a mechanic. The mechanic should check the ignition switch , the ignition coil ,the starter solenoid, the spark plug ,the spark plug cable , then the battery. if there is a malfunctioning or worn out of these said parts then you have to repair it or replace it. then you also have to check the wires if there are loose wires or worn out wires then reconnect if loose wires but if worn out then replace the wires.the most important for some times is the fuse if there i a worn out fuse you have to replace the worn out fuse. But if the fuse you replace cant hold the wat/amp of the bike then place fuse that is higher than the former fuse you place.

The ignition switch is bad. Mine did the same thing when it went bad. The switch from HD is about $60.00 or you can buy an after market switch for about $20.00. Real easy to change.

Not getting fire from coil

Do you have a manual? If you do can you send me a copy of the correct schematic for your bike. It will me help you if you can scan a copy in to send me. If you don't already have a basic voltmeter that measures resistance. You should pick one up at either WalMart or even better Harbor Freight has the best deal $4-$9 there. What year is your bike? You can start off by isolating the kill switches from the coil by unplugging the coil lead headed towards on/off switch and other safety switches. The idea here is to make sure you don't have a bad switch by disconnecting all kill switches to test for spark. If still no spark does the bike have cdi box or points fire ignition. CDI is capacitor discharge ignition often refered to as the black box. Points are mechanical switches that open and close riding on the crankshaft.
Please send year of bike so I can better assist you.
Thank you,
