oscar, in your original post, you say you put on a new set of wires. do you still have the original wires? if so, try putting them back on and checking for start. could be bad wires.
Nope!

The one thing I didn't hold on to. I try to save some of the old shit just for this reason but those hit the can before I could've thought to hold on to them.

If you get fuel out of the line at the carb... the filter wouldn't be the problem. THe only way the filter would hurt then is when your romping on it and it can flow enough to kep up with the carb/motor demand.

Spark plugs... a real easy way to check to see if the coil is firing... just use a spare plug... put it on the wire, place the grounding tip to the head and crank. Look for spark.... if you can't tell for sure... do it in the garage with the door shut... but it should be obvious.

If your concern is the spark plug wires... you can pull the wire at the coil, leaving the spark plug in the motor and hooked up and crank... see if it arcs from the coil to the wire.

While looking at the EHC, turn the key on... no lights should be present. Then push RUN, one light should come on. ***This being your EHC is somewhat current***

Then, check your thunderheart ignition. When you crank you should get lights flashing on your ignition module. I'm not sure but I bet yours looks a bit different. But I think they still hv lights on it...


For the one above, the red light to the left would come on when you push RUN and the EHC sends power to it. The other 2 lights are one for each cylinder fire that the unit sends to the coil.

Also, maybe check to see if there is a reset button on your coil. Some do.

Further, check your crank sensor as well.

Oh, and you're not starting it with the throttle open are you?

Thanks for all of the info. Chris. Negative on trying to start it with the throttle open.

As far as the EHC the red light does come on when I press the run button.

Now I have this Thunderheart block that has a red light but it's not on. Not sure if it's supposed to be.

I checked for spark like you suggested Chris. I got nothing.
Oscar, if you pulled your coil cover when you changed carbs then I would recheck the connections in there to ensure you got them all tight.

You had spark before so seems you have a disruption and most likely the connections under the coil cover.

Check it out.

Thanks Ray. I plan on doing that tomorrow. I'm kind of beat and have to go to work in the morning. I'll keep you posted.

Good call Ray. Although you said you had the bike running before... check the location of the wires. Plus use a multimeter to check power it should read the same as the battery with the key on and it on RUN.


But you telling me that the light on the thunderheart is not on... makes me think its either the ignition. Unless that is only suppose to flash when cranking. Maybe Alhall or somebody else with the older dogs can tell you if their light is on.

Do you have a crank sensor or cam sensor?

Crank sensor is on the front left of the motor between the stator wires and the oil filter.




The cam pick up would be in the cam cover where my 2Ki is.


But it would be a flat plat with a single pick up similar to this


Under it would be a pick up cup on the end of the cam (which I'm sorry is not actually in this pick, just a naked cam end)


However, if you remove the cam sensor you will have to reset the static timing. The reason I suggest this as a possible is you can have it fail or blow up like this


And Yes... Sul is right... the flow charts may help as well. But they can be SOOO dry and technical. Which some people shy away from when they are frustrated like I'm sure you are.

Gas Man - But you telling me that the light on the thunderheart is not on... makes me think its either the ignition. Unless that is only suppose to flash when cranking.
I thought at on time if I'm not mistaken that little light did turn on. I can't remember. I think I'm going to have to keep a record of all that I've done and been doing to the bike.

I followed the flow chart that Sul recommended and it seems to lead to the direction of the coil. I won't be able to tell until tomorrow until I take the tank off of the bike. Unfortunately its the only way that I'll be able to see if the coil wires are hooked up and grounded. Wish I had the room to check without having to take the tank off the bike. Tomorrow afternoon I'll get back to working on the bike and I'll keep you all posted in what I find. Thank you for the help until tomorrow.

Have a few beers for me. I'm going to sleep.

might as well check the connections at the coil before you take the tank off - you never know it could be that simple

With the ignition system not giving you any spark... its best to follow its path. It starts with power to the ignition itself, then its signal comes from the cam or crank sensor, which tells the ignition to fire which cylinder when it sends power to that coil lead.

Check the wires at the coil and be sure you have power there. If you do, then it is either the sensor or the coils. If you don't, I'm willing to bet either your EHC isn't giving the ignition power or the ignition itself is bad. Or maybe far option of the controls not telling the EHC to give it power (the RUN not working).

hard to believe it's anything that complicated. check the resistance of the new wires with an ohm meter. may just be too much resistance not letting enough spark get to the plugs. ain't tryin' to step on anybodies toes, just tryin' to be logical.

I agree with woodbutcher about checking those wires again. Simple troubleshooting start with the simplest and work from there. Since you did change the spark plugs wires and unfortunately threw them out, seems like a good spot to check.

If not already, get the ohmeter out and check from end point to end point on each spark plug wire and may sure there is not an open/break or too high of a resistance as well as making sure that the metal connectors are getting good conductivity from the core wire.

Thanks guys,

I didn't get a chance to do it yesterday or last night due to my job but I will mess with it this week.

Once again I appreciate the assistance from you all that have helped me this far.

I did get a chance to utilize the flow chart points me in the direction of the ignition coils, I hope the flow chart can be somewhat close seeing that it is for the years of 05' - 08'. Anyhow I'll be messing around that area this week.

Thank you all again.

Run switch??

Check the points on the pin connector for the run points for getting power to the run switch and back to the EHC. Could have gotten wet possibly.
