    Hello, haven't been here for a while ... bike was running good so I didn't need to ask a 'how to fix' question. Many people here with more knowledge than me. My problem on my '01 Dyna is that I'm not getting any power to it.The lights, turn signals, neutral switch light don't come on when I turn the key to 'Run'. Doesn't even come close to starting ... nothing. Turning the key back to ACC, I get the speedo light/odometer, and horn. Nothing else. I checked the battery and it read 12.3v ... charged it before taking it up to O'Reilly's for a check. It started fine this morning at home. No problems. Went to the bank to cash my unemployment check.... shut the bike off and started fine. Went to get a coffee and that's when it wouldn't start. Happened without warning. I'm thinking ignition switch ??? Any other ideas ?? 2001 FXDL with 19000 miles.
    Thanks to all ... you've helped me in the past. Thanks again

    Did you check the battery post, nice and clean and tight? Might check the wiring to be sure everything is tight. Others might have more suggestions as well. Electrical can be simple but hard to find sometimes.

    the posts on the battery looked good as did the connections on the cables. I didn't check the fuses yet. My suggestion of the possibility of a bad ignition switch doesn't fly because my speedo/odometer stays on. I have separate speedo/tach on the gas tank. I would think that it too would go off like everything else when the key is turned to 'Run'. I'll check all the fuses and see what's up. Thanks for the suggestions.

    if your wires have ever been spliced due to putting on differn't bars that could be a start had that happen to me before. or some times in the hand controls they get mashed and cause a bare spot that will short out a fuse

    I wouldn't think it to be the 30amp main, since the speedo lights up. That is my way of not pulling the battery when I work on the Sporty (uh is that a bad idea has worked so far but that don't mean it is right).

    I would think it is one of the other fuses, or a broken ground. I would start with a continuity check across all the fuses and then wiring harness under the tanks, or around the bars like Sportsterboy said if they have been changed. I woudn't think it to be the main ground since some stuff works and some don't, it is in between the working/non-working areas.

    Good luck, let us know what turns out.

    Sense it sounded as it was intermittent because it worked for a while then it didn't that it has to be a wire issue. If it was a fuse it wouldn't work at all. So need to check those wires, could be a wire that got pinched and now has a bad area in it.

    First thing, check all the grounds, make sure they are clean, tight and have good contact.

    I'd bet on the bad switch, if power is coming out one side to the accessory side 100% and intermittent to the other then the contacts inside the switch may be bad.

    I would pull the switch and check the output voltage with a meter at the switch, do a wiggle test, lightly twist the switch to see if you can cut power by just barely moving it.

    If everything won't come on or shuts off when you go to the ignition side, either the switch is fubar or, the wire coming of the switch is bad.

    Good point on the switch didn't think of that and a good place to start.

    Well a little experience with this problem in the past.

    I had three give up the ghost on my Heritage, even to the point of overheating the switch and wires, cut off the bad ends (wires that get fried tend to get worse increasing draw and ruining the second switch)

    Make sure the connector is on properly and the wires clean and solid connections

    Thanks for all of your responses. I stopped at Motor City HD to pick up the 30 amp fuse behind the fuse box (on a superglide). It was only $10. When I get the battery hooked up again along with the fuse, and if everything is still the same, I'll go to the ignition switch. Like it was mentioned, if the main fuse went, why do I still have my speedo/odom come on? I think my turn signals operate in ACC., to where I can remove the key but keep them on flashing as blinkers, if I happen to be along side the road. I didn't splice into any wires. I do have a Kuryakyn brake controller module that makes my turn signals into blinking brake lights, but that snaps into the exsisting harness. So ....HRK and FLHT and the rest of you, thanks for the input. p.s. is the switch you talk about the ingition sw. ??

    Sounds like the IGNITION contact on your ignition switch has given up the ghost. That's why things still work in the ACC position. Quite common problem

    Thanks for all your responses. It's a bear sitting around on a beautiful three day weekend here in Michigan going thru this schematic. I changed the 30 amp. ... that's not it. battery and connections are good ... had that checked at the shop. Thought it might be my TSSM with all the wires conecting to it that connect to the items that aren't working, but the tech at HD shop says it will smell like burnt wire if it was bad. Checked my ignition sw. thru the fuse box ... that's o.k. The next thing is my starter module, which looks like it runs inline with my instruments, starter, and lights circuit. Is the proper way to check continuity on a harness to place the meter probe in the socket end of the harness and ground the other probe on my meter to a ground on the bike? I should get a reading when checking the ground wire on the harness connection too ??? I want to make sure I don't get any false readings. Thanks again all, and have a good Labor Day Weekend.

    With a little diligence, I found out I have a bad ignition switch. The red/black wire is bad. That's the wire feeding the hot side of my fuse box for my ignition, lights and instruments. HD wants $108 for a new one. I know J & P, Jireh and others cost about a third of the price. Has any one had to replace a switch and where did you purchase it? It has to be a three wire switch. Thanks

    I would go with the sw from HD others 1/3 the price in my experience = 1/3 the quality. Other thing to remember after replacement is to not hang heavy key ring from sw. This is common reason for sw failure. Thats what i have seen in my experience. Good luck....Steve

    If you can stand waiting a bit for the switch contact one of the three dealers below all work well, all give 20% off, check because sometimes the "retail" price is higher at one or the other

    Mansfield, Ohio, Harley-Davidson, Buell, Motorcycle Dealer, Hale's Harley-Davidson

    Chicago Harley-Davidson

    Fairfield, Ohio, Harley-Davidson, Motorcycle, Dealer, Used, Parts, Acccessories, Apparel (you have to ask for Jenny)

    Don't order one with your key, you can swap keys (at least on the big twin) not sure about dyna so you need to be sure you can remove the key barrell from your bad one.

    On the heritage it's simply a clip you remove, flip and lift the chrome part out of the black connector housing, you'll see two brass clips and springs do the old one first so you learn whats where.

    Then just transfer the chrome housing to the new switch, and you have your stock key...

    Check the wires coming out of the switch make sure they are in good condition, if they overheated the wire will be hard and non bendable, cut out any bad ends and put on new HD clips, insert in the plastic housing..
