My 2003 bike was having trouble starting. When I turned the key I would get the neutral and oil lights to come on but when I pressed the starter button nothing would happen. No sounds, no attempt to turnover, nothing.
If I wiggled and cycled the ignition key I could eventually get the bike to start. The problem occurs at an increasingly frequent rate over time. At first it was only once in 100 starts, then every 50 starts then rapidly it went to about once in every 10 starts or less.
After checking the battery, battery connections (wrench them tight), and doing a lot of reading on this forum, I decided my ignition switch needed to be cleaned.
The Vulcan Verses has a nice write up here : https://www.vn750.com/forum/showthread.php?t=1133
. I'm real new at doing anything besides changing the oil on a bike (thanks Harvey_Birdman and others for the write-ups) so it took me a little over 2 hours to work through all this. I took photos as I went along and placed them in this album: https://www.vn750.com/photopost/showgallery.php?cat=701
The photos show the disassembly and cleaning. Reassembly is pretty easy, and just does the disassembly in reverse.
Give yourself some time and work room on both sides of the bike and I think anyone should be able to do this cleaning using the Verses and the photos. If you take it apart and find busted solder connections you'll need to know how to repair them and that can be a little more complicated. Mine just needed to be cleaned.
Crobins365 has posted some good photos of the entire ignition switch removed from a bike. It shows both the mechanical and electrical parts of the switch. Photos at: https://www.vn750.com/photopost/showgallery.php?cat=624
The photos are of a 2003 Vulcan 750 sitting on it's center stand.
Good luck, hope this helps someone.
REMEMBER TO DISCONNECT THE BATTERY BEFORE YOU START OR YOU MAY START YOUR BIKE WHILE WORKING ON THE SWITCH.
