mine and my buds 04 had same (similar) situation. Coil was bad.

is there a way to test the coil?

is there any easy way to get to the cam sensor i pulled the cover and looks like i have to remove my pipes and pull the whole main cover off as it shows nothing with the round cover removed?? Ok #1 i never dug into an electrical system so treat this as i'm blind lol i need pics and detailed info if posible. thanks going to change my name to MeatHead cause right now i feel dumb lol

Don't pull the whole cover! Thats supports the cam and lifters and valve train under spring pressure and doesn't sound like its your problem.

You can't reach a tester to the coil contacts to make sure you're getting power?

Have you had the battery out? If so did all wires get reconnected?

yes all wires are connected and in good condition, i have to pull cover to get to it so i have to raise the tank to get bolts outta the cover over the coil etc

No room for a hex wrench or hex bit and use a open end wrench to keep from pulling tanks.

ok how do i test it. With a test light? should key be on or off etc?

 

[mobsta]

key on hit run,use test light,there is also a trouble shooting guide here for your no spark problem,read it last night for refresher ,use the search tool,type in cam sensor and read some of the threads,thats were i found the guide,someone had it listed

 

[mobsta]

if i remember right but again at my age,if you dont have power at the coil its your cam sensor,if you have power to your coil its your coil thats bad,again look up the guide,i will look again to see where i saw it,

 

[mobsta]

ok i searche cam sensor,look on the second page the thread is no spark on 2002 mastiff,read the thread there is a trouble shooting link that someone posted,you will also need to check power to your cam sensor,if no power there it could be your ehc or may be thunder heart,one more thing you might check is the relay under your seat,theres alittle button on it try pushing it in.good luck

cant find the relay?

ok according to the guide if you have power to the coil its your coil thats bad,have you tried cranking it over in the dark to see if theres any arking around the coil or wires

no had to lift my split tank to get the cover off turned on key hit run there is power to both sides of the coil. Don't think i wanna turn it over as the gas is slowly leaking cause the slit tank is up in the air lol

Yep does sound like coil.

Also might check a plug wire as well. Baby ray had plug wires go bad on his bike. wouldn't run, then run one cylinder, then be okay. We checked lots of stuff and new wires solved the prob

 

[mobsta]

what do your plugs look like?wet,black

 

[mobsta]

thats what im thinking also ,thats kinda why i would crank it in the dark looking for arcing or some sign

 

[mobsta]

can i ask a stupid question here?how did you check the plugs for spark in the first place

 

[PureDestruction]

found one of my plug wires is starting to burn through the rubber from rubbing on the cover but still doesn't explain why i have no spark to either plug and the thunder heart does not light up

 

[PureDestruction]

pulled plug held it against jug by the spark plug hole makeing sure it grounded

 

[PureDestruction]

my plugs are wet with gas but not black i put new ones in and its still the same won't fire

 

[mobsta]

ok give me a couple of minutes here,i am going out to my bike and look at something
