Starting Issues

Hello,

I bought a 94 vulcan about 2 months ago. It ran fine then one day it just wouldn't turn on. The lights would come on but the ignition switch would do nothing and the starter solenoid relay would not click.

If I jumped the solenoid the bike would start. So i ordered a new starter solenoid and replaced it. Still nothing.

I took apart my the ignition and kill switch module thing and cleaned everything and tested it. I was getting 12V to both the kill switch and the starter button.

I tested the switch out and the bike turned on. So i turned the bike off and put everything back together. When I went to turn it back on the starter switch didn't work again. Removed that assembly again and this time i was getting 12 to the kill switch but no voltage to the power wire going to the push button! Also, now the bike wont turn on when i jump the solenoid.

(While doing this i noticed some lose wires going to my turning signals. Some had power others didn't. My turning signals would only work at random since i bought the bike. The gas gauge doesn't work either, could that be causing the short). I didn't mess with them, just wrapped the ends in electrical tape for now, because I'm not really worried about the turning signals now, just want to get it to turn on.

I don't know what to do next, I'm not too familiar with bikes and much less electrical issues. Any help is appreciated.

Thanks.

Ck your ground wire from battery ground terminal to frame! That is a good starting point. A simple thing like a bad ground will run you in circles on a DC volt system.

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.

The sidestand switch shouldn't matter, but you might want to check that while you are at it.

With the bike in neutral and the kill switch in the run position, either the start button or the kill switch could be the culprit. The sidestand switch only kills the ignition if the bike is in gear and the clutch is released.
If the bike is in Neutral, then the clutch won't matter either.

If you are sure the solenoid works...check all connections and fuses for intermittent connection. polish the contacts on the switches and verify they make a good solid connection with an ohmmeter.


Good luck

Not quite all true kc2dgq. There seems to be a lot of confusion about exactly when the sidestand switch prevents the engine from starting, or kills it when it is running.

The engine will stop if the transmission is put in gear with the sidestand down.
Likewise, the engine will stop if it is running with the transmission in gear, with the clutch pulled in, THEN the sidestand is lowered.
