no spark

Hey guys..I've been having a problem getting my bike started. Anyways, we figured out that there is no spark. Do you have any idea of where we'd look

 

Could be several things, go through this list.
1 ) Battery, is it fully charged? What is the voltage when starting?
2 ) Fuses, are they good? If you have the OEM fuse box consider replacing it. Make sure all connections are clean.
3 ) Side stand saftey circuit. Is the relay grounding the TCI?
4 ) What is the voltage at the TCI when starting? If it is below 10.5V it will not work. Check and clean connections from the battery to the ignition switch.
Thats a good start, there could also be a problem in the TCI. We'll go there next.

 

Thanks for your info. To answer the questions in order.

1). No, the battery is week, but I had cables connected to a car when I was trying to start it.

2). Fuse box is crapped. Connections are wobbly, but still make a connection so this is why I didn't think it would be that.

3 and 4). I have no clue

 

I should add that I can press the start button and it sounds like it is making great attempts at starting as per usual, but no go. First we thought it was gummed up carbs, but then the spark plugs were tested and we saw no spark

 

I had the same issue with no spark on the xj 1100 and it turned out to be one of the safety switches

Manual states for when engine will not start:
check ignition circuit for connections
check battery voltage
check fuse and fuse connections
check ignition coils
check pick up coils
check operation of emergency shut off switch
check operation of sidestand switch and relay
If that is all good
replace tci

this is from xj 1100 manual, but i am sure same procedures will help find the problem
Hope this helps
I would personally check your ignition fuse first

 

One of the ignition coils is pooched. This is stupid. I can't even find the part number of the fische. Why would one crap out ll of a sudden
