i turn my key over the other day and go to start the bike and nothing then i turn the key off and try to turn it back on and get nothing no lights on the speedo nothing let it sit did it again and it starts then it dont big cycle i have an 07 nightster any help fellows ????

 

Check your battery cables for tightness...if that's not the problem - run meter on posts to see if it's charged...should be @ 12.6V - 12.8V.

 

+1 on checking the battery cables for "clean and tight" at both ends of both cables.

07's are also know for water/corrosion problems in the fuse block/relay area. Remove the fuses and relays, clean the contacts and coat the with dielectric grease, then reinstall.

I have no clue what "then it dont big cycle" means.

.

 

like its a big continuous cycle of starting and not starting

 

Check your fuses for corosion. Happened to my wife and had to have her bike towed. We washed the bikes and went for a ride, came to a stop and it would not start. We pulled and checked the fuses and all were good. Next morning just for ***** gave it a try and sure enough fired right up. I jumped on it and rode to the dealer. There were no trouble codes or anything so I got no expalantion from them. I read somewhere about the oxidation and sure enough the fuse conections were oxidized something bad. We live in Washington State (tons of humidity) and our gagage is more of a shed so that probably contributed to the problem even before washing hte bike. I wireburshed them off, added som dielectric grease and have never had another issue with it...worth a try anyway.

 

thanks guys yall are the S&!%

 

could it be the ignition switch going bad?

 

This happened to me just the other day, so here's my .02
My mechanic thought it was the crane ignition gone bad, swapped it out, I picked up my bike and it died again just a quarter mile down the road from the shop. He spent some time scratching his head, pulled out his meter, found the problem. The wire harness connectors in my bike are worn out from age. The wire that supplies power to the start stop/run controls on the handle bar. The pin connector was loose and barely making contact. So it ran when it wanted, not when I wanted. Transferring that analogy to your bike. I doubt your bike is an 80 sportster as mine is, but yours sounds like an electrical connection issue as well. Check and double check all the connection points. I'm cutting out the connectors and soldering the wires together this weekend, getting rid of the spaghetti (wire ball) in my headlight assembly.

 

I had a similar issue recently, +1 on checking the battery cables. Mine appeared to be good and in working order but had some "green wire disease" under the wire loom and heat shrink tubing.

The result was the infamous lights would come on, touch the starter button on the handlebars....and "click, lights out".

From my research and troubleshooting check your ground cable has a clean solid mount to the frame or in my case, engine block. The positive cable goes directly to the starter, mine had so much corrosion the lights would operate but couldn't support the amps requested at startup.

Those cables are measured to length and pretty tight that connect the positive and negative battery terminals.
