Is the neutral light working?
93 vulcan 1500
I customized a customers 93 vulcan 1500 and for partial payment he gave me another 93 vulcan 1500 in a basket case form . The bike is a parts bike that the guy bought off of ebay for a engine swap . The engine and frame is very clean , no signs of misuse or wrecks. So i bought the parts that have been taken off the bike and today i finally got the fuse box that i have been waiting for . I got all the electrical connectors back together and a new battery then I got it to turn over! Everything looks good so far... but no spark. I checked with a spark tester and no spark . I checked the leads to the coils and there is 12 volts but still nothing . I depressed the kickstand switch and then let it out and didnt seem to help . I havent checked to see if the switch is working yet but I would like to know if there is any other switches that I would need to be aware of that would turn the coils on ? oil pressure switch maybe ? I did notice that there is a vacuum port coming from the ic igniter box that isnt hooked up . does that have anything to do with it not sparking ?
Please help out with issue Ive worked on many older bikes but nothing this new yet .
Any suggestions ?

Yes I put it in gear and light went off . Just tested kickstand switch and it works
What does the vacuum hose at the ic igniter do ? I've looked everywhere and can't find any info on it
The hose connects to a vacuum tap on front carb. It provides vacuum advance signal to ignitor.
Is the factory ignition key switch in place?
Is the factory ignition key switch in place?
Yes the key is in the ign spot and power is on . I'm thinking possibly the pick up coils are bad or the igniter box is bad . I have power to the coils but their not being turned on .
OK, but is the key switch factory original or is it aftermarket/modified/etc?
Yes its the original . I think I may have it narrowed , I checked the kickstand switch again and it's good , but there is no voltage going to the switch to create a full circuit . I checked the online manual and found that the switch goes back to the igniter. So i checked the by using my multimeter and found the wires that ran back to the igniter box .there was voltage at the box, So right now i'm assuming there's a break in the wires somewhere or a bad connection . Got any other suggestions ?
Neutral light trumps other interlocks, so stand switch is not an issue (yet).
Could you do the following:
1. Take voltage reading across battery.
2. Turn on key and take another reading.
3. Leave key on for a full five minutes and then take another reading.
4. Turn off key, leave off for 5 minutes and then take another reading.
Post back with 4 readings.

I am willing to help here if you wish....
Sorry man haven't been on the net today . Well I went through my wiring tonight (and made a mess lol ) came to the conclusion that my coils are shot . I found that my kickstand switch is working and I used a meter and seen that the pickup coils are working and the coils have voltage at the plug but no spark. I ohm'd the coils and they're bad .
Are you SURE they are both bad? That would be one giant fluke and those coils give very little problem.
Did you test them by the voltage drop method?
Kickstand switch has no influence when bike is in neutral, so do not even bother with it, yet.

Be aware the coils have a live circuit. It is only grounded by the igniter when the signal from the pickup is received causing them to fire spark to the plugs.Sorry man haven't been on the net today .

So does that mean that the igniter needs to be grounded ?
Igniter is grounded thru a black w/yellow wire that is in the harness plug.
If both coils are indeed bad, then something might have caused them to fail together and just installing two new ones might result in two bad ones again.
The ignitor should be checked. Post back if you want help with that.

Cool thanx man , I'll have to wait till this weekend I have customer bikes to work on .
Well I'm starting to look at the igniter now . I got my coils in today and ohm'd them and rechecked mine to see if anything was different . It appears they are the same,obviously I read them wrong last time . Good thing the coils are cheap on Ebay lol ! So I checked the pickup coils for a signal with my meter with continuity and detected them working .Kinda weird I could get a voltage reading with my meter as 12 volts but I used a light tester and it didn't turn on. So I'm thinking it's the igniter or a grounding issue . I've gotta say this , it's a learning adventure for me on newer bikes. I can work on older bikes and have no issues ! Pretty straight forward lol ! So my next question is , Can I bypass anything to excite the pick up coils and get a spark ? So I can know where to turn to next.
Thanx
Thanx
