Coil on #2 and 3 not firing??

[Kato76]

Hey all, I has this post a few weeks ago regarding gas mileage. Everything was pointing to a bad coil pack. So I got a new set of coil packs from Bikebandit. Change them out, tested them and then there was nothing; #2 and 3 are still not firing but if I switch them it will fire 1 and 4. So I'm now curious of what's going on. The coil pack is good, once connected nothing. I tested the connection when I turn the bike over it is getting something, but not firing the coil.. I hope someone has some answers because I'm all out of them.

Please help its starting to get cold and I would like to ride it a few more times before it's too cold to.

Thanks in advance.

Umm left coil is 1 & 3 and right coil is 2 & 4. If 2 & 3 are not firing then the issue is more likely related to either fuel/air or plugs.

[Kato76]

The plugs them selves aren't firing no spark coming from the plug itself... I just bought brand new ones... still lost... :-(

Take the plug wire off the plug and hold it against the frame of the bike. Does the wire spark?

[Kato76]

Nope.. tried that.. no spark going to the spark plugs..

Time to get out your multi-meter. You have an electrical short or ground some place. Its not located on one specific coil its affecting both. Sorry cant be much more help.

IIRC, left coil does 1 and 4, right coil does 2 and 3.

Hi Kato76,
I put the attached picture together for another thread, but maybe it will help you. Things to check: 12 volts going into the coil primary. At the points where the other lead of the coil primary connects to the points, do you have 12 volts when the points are open and 0 volts when the points are closed. Try disconnecting the condensor. It might be shorted.

Assuming you have points. If not, same principles apply . . .

Either bad connection at or before the 2&3 coil, bad igniter or bad crank trigger.

Thanks Guys looks like I have my weekend cut out for me..

[Kato76]

Uhm... where should I start...

[Kato76]

OK I checked the ground it was a bit rusted so I cleaned that up.... still nothing

I did check with the Multimeter, up unto the Coil pack it's self, and I'm getting voltage up to the pack... but still not spark at the plugs..I checked the plugs and they are good.. made sure the gap was good.

So I opened up the area where the points are and that's where I got confused I'm not sure what I am looking at and what needs to be tested for voltage..

so if someone can give me an overview I would appreciate it

thanks

New Information

I don't have points or condensors, I have an electrical ignition that has pick ups...

I got this information from a gentleman who I work with..

does this sound right....?
