ok im driving to work yesterday everything is fine...then one cylinder stops firing ****...so im like well i will hobble it home on one cylinder prolly a spark plug or something. so i try to drive it back home after work. both cylinders die....and it wont even crank. i check the fuses the ignition fuse is out i replace it. drive it 500 feet blows it again so im like crap i have it towed. i checked the codes from it im getting a code 24 which is front ignition coil code. so i take the airbox off and i look at what i believe to be the ignition coil. has spark plug wires running into it. well its got some sort of orangeish goo on the side of it possibly cracked? so is this a pretty cut and dry part replacement here. im pretty new to the bike world (3 yrs) but ive always worked on my own stuff. where can i find parts for this online and is there anything i need to know to check out while im replacing this part? | ||

What kind of bike? on the Xb's its pretty straight forward, but you have to be a contortionist to get the the front plug wire off the coil. Remove negative battery cable. remove three wire connector from throttlebody side of ignition coil, lay aside. remove both plug wires and lay aside. remove two fasteners, and pull out old coil. Install new coil the opposite of removal, and torque fasteners to 120-144 IN-LBS. You could also test your old coil with an ohmmeter. Looking at the coil with the connector facing you, you'll see three pins. going left to right think of them as p1 p2 and p3. measure resistance from p1 to p2 and p2 to p3. You should get .5-.7 ohms between p1 and p2.. and between p2 and p3. also from the left post (rear sparkplug) to p2 you should see about 5.5-5.7K ohms and same for the other post to p2. Good luck! | ||

yeah its an 05 xb12s. ive got the coil out but cant find my multimeter anywhere :-/. but it has a huge crack in the silicone looking material and a brown sustance has leaked out and since hardened again. but i plugged it in and turned the bike on (running on one cylinder and its not firing out the front plug. | ||

ok new news to add...got the new coil put it on still runs on one cylinder and im pretty sure it fried the new coil..soooo what causes coils to fry like crazy? | ||

Check your plug wires, and sparkplugs. If the front cylcinder wasn't run for a while (due to old coil being bad) it could be a fouled plug. Also the plug wire connection at the coil could be burned as well. No idea why a new coil would be "fried" instantly. I would check with the cheapest most basic "fixes" ie wires and plugs. | ||

but what i cant understand say it is the plug or plug wires...why would it overheat my coil to the point of cracking. and also blow my ignition fuse from too much power being drawn? i just did some diggin in an old post and found where someones 09xb92 had been frying the coil also. http://www.badweatherbikers.com/buell/messages/3842/386351.htmli checked all of them and the sensor ground (pin 7 on gray plug) is not grounded. should it be? and is this causing my problem with overheating issues?
