2005 Vulcan Classic Kawasaki 1500 F.I. was running fine, let it sit up, battery died, new battery in, now there is no power at all. No Ignition lights, headlights,signal lights, no sound at all when hitting the start button. Checked cables on battery. Help!!! Charles

Unplugging the sidestand switch will not bypass it...

TO ALL VN1500 OWNERS....This once happen to me,
I went to the garage to start the bike "Nothing ""The first thing is the lights are bright but no turning over,Next you think the solenoid is kaput but the answer was very simple and the fix takes 30 seconds..
Do not take the bike to bits looking for other problems and look at the clutch leaver and you will see some wires going into a plastic shroud going into the switch in the clutch leaver, Make sure this has not popped out if its connection as it some times may do after a few years due to constant turning on the handlebars,
When this is not connected you will have a bike that will not fire up but comes alive and you will hear a clicking noise but this is from the engine carb area and every function of the bike will work but it will not turn over, Worth looking at and saves sixteen quid for a starter unit you never needed.

There is a sensor on the kick/side stand. Check it is not faulty as if the bike thinks it is down, as you release the clutch it will kill the ignition.

Check the ground wire at the battery, at the negative post at the battery you'll find a smaller (black/yellow) wire, it must be plugged into the main harness, it might have become unplugged, the connections will be right close to the battery.

keep pressing the starter and find out were the click is comeing from,, then change the starter solenoid, it sounds like this is at fault

you might have a charging system problem without the bike charging system it is only running on the battery power, and once the battery is too low to fire the ignition it will die, check your fuses and power cables to the battery, selenoid and starter, then check the regulator/rectifier, could also be your stator or rotor, only a few possabilities but you will find it.

go to gadgets fix it page, they have diagrams and step by step instructions to do this, i use his site religiously you can find anything there about your vulcan
