when it wont start, do you hear the fuel pump priming?

 

I am glad i can finally help someone out. i had the same problem with mine. After changeing the battery and taking it to the shop 2 times they finally told me that the Regulator Rectifier is getting hot and shutting off. I replaced mine with a Ricks Rectifier and no problems however the bad rectifier made my battery go bad so i got a new one free (warrenty) Hope this helps let me know.

 

yes, everything just like normal wants to turn over but no spark, till the next day, already been threw all the grounds also.
Thank you for your reply

 

Here's a link to doing the diagnostics on the r/r and charging system.

Good chance this is the issue, however check all of the connectors in the harness,
as well. Look for any sign of heat damage. Usually, the issues that come and go are
electrical/heat-related. If you find any signs of heat-damage on a connector,
closely inspect/test whatever component that connector goes to.

Hope that helps, Ern

 

Sounds exactly like the issue I posted about that Ern had suggested about checking the connections for clean connections, etc.

 

Thank you all for your help I will defintly be testing that and will let everybody know if that is the issue, Hopefully I can get it going and be riding soon.
Thank you again everybody
Craig

 

UPDATE.......Thank you for all the help, It was the Regulator Rectifier, got a new one put it in and PERFECT. Thank you 08cbraf, and everybody for looking at the post and all your help
