So, a year or so ago i was riding home, bike appeared to be running just fine, and i stopped to run into a store.
I came back out and the bike would not start. It would turn over just fine, but would not start up.
I replaced the battery because it was suspect anyway, not luck.
I got the bike trailered home and never really went back to look at it.
Well, i want to get it running again.

Here is what i know :

Fuel is flowing to the carb,i am not sure if it is getting in the carb, or getting to where it needs to be inside. ( dissasembly/ cleaning will be in the near future )
I removed the air cleaner and sprayed some fuel directly into the carb, bike was turning over but no combustion.
I pulled the spark plugs and they dont look damaged.
I tried testing for spark with a continuity checker ( little light bulb lights up if there is power ) and i got nothing.
Battery is low now, so it's charging back up for more tests.
Fuses look good.

Any suggestions where to look next?

Thanks !

Hi!
Just test Your spark plugs the easy way. Take them both out and do the following to check if there's a spark.

Ok, i did the test in the video. No visible spark on either cylinder.
I found a thread here between Sfair and AaronBBB that i am reading.
http://www.vulcanforums.com/forums/56-vulcan-800/30037-no-spark.html

I checked and my neutral light is working, so that's good apparently.
Factory switches etc all worked before this issue.

Today is my only day with easy access to a parts store for a week, so i think i might swing by and get one of those spark testing tools. I'm also going to pick up some fuel line, the stuff on there isn't looking too good.

On a side note, the reason my bike sat so long was because i had reliable transportation, so no need to fix it. Well my Jeep was hit by a Honda and is in the shop, and the rental coverage has expired :(.
Thankfully i can carpool to eliminate most of my issues, but i hate not being able to go somewhere when i want. 2 weeks left of work on the jeep supposedly :(

No luck on the tool listed in the other post. They had an inline tester with a light, but it's to big. Same issue AaronBBB had.

OK. Then let's continue the easy way ;) Do You have a service manual? There's an electric diagram in it. Just follow the ignition line and test the voltage on any available contact. Start at the ignition coils. Apparently, this is not the spark plug fault, if You have no voltage on ignition coils... So, search further only on ignition line, first.

test the voltage on any available contact. .
I do not recommend this method as it is a good way to introduce another problem and then the real tail chasing begins. Using a logical troubleshooting method will produce better results.

1. How many miles on the bike?
2. Do you have a meter and know how to use it? No meter, we can help there too.
3. You still have a no-start condition?

D'oh! :cow: On every contact in ignition circuit! The easiest way is to follow the wiring diagram and check through.
Sure, the multimeter would be great, but if You do not have one, You could use that simple testing bulb method.

15,400 miles on the bike.
I have a meter but i've only really used it to check voltage/continuity. It's the free one Harbor freight often gives away
Digital Multimeter - Save on this 7 Function Digital Multimeter

I still have a no start condition. I tried spraying a little gas through the carb with no results. When i pulled the plugs after that they were a little wet. So i believe gas is getting there.

OK, do this first:

1. Take voltage reading across battery.
2. Turn on key and take another reading.
3. Leave key on for 5 minutes and then take another reading.
4. Turn off key, wait 5 minutes and then take another reading.

Post back with 4 readings.

Do not spray gas. It could result in a fire!

1.started at 13.15 volts, but dropped to 12.8 within ~5 seconds
2. 11.89 volts, and dropping slowly
3. 11.82 volts, did not appear to be dropping
4. 12.18 volts, looked to be steady

As a side note. When the bike broke down initially, i replaced the battery with this one, thinking the old battery was the culprit. The bike has never started with this battery. It has sat for almost a year without me doing anything to it. It was on a battery tender over night.

Neutral light works.
By battery boost do you mean jump start? I used one of those jump start battery packs with no luck. This was on the previous battery. I have not tried to jump start with the current one

Ok, on the ignitor:

1. Locate grey wire going into connector on ignitor.
2. Push red meter lead down beside grey wire in connector to make contact with metal pin, connector still connected.
3. Black meter lead to battery ground.
4. Key on, take voltage reading.

Post back with reading.
