Thanks for the reply!!

When I hit the run button, I have great power everywhere (where there should be atleast) However, The LED does not light up on the thunderheart.. So im guessing its my cam sensor.. Does anyone know where or what part # I should order?? I guess ill go ahead and replace it and start from there.

Or Ive done some research and seen Crane cams makes a nice kit Comes with Coil, Sensor and Wires? Is that easliy installable or not worth it?
If you are not getting a red led to light up on the Ig. module up when you hit the run button and you have power at the ig. module, I would start with the ig. module.

I understand, However when I left the key on and unplugged the module then plugged it back in, The red LED did light up, Not for long.. However I Guess it could be bad... Where would I go about to get a replacement? or upgrade?

Ok, did a number of tests... I got power to everything I checked for an arc from coil got nothing, Got power to coil, Got power coming to and leaving the thunderheart so... Im going to have to say its the coil... On the cam sensor I took that all off cleaned it throughly, Looks like its in good working order, However i think I may have to replace that aswell.. Because sometimes my bike would die so that may have something to do with it.
Without a multi-meter how did you determine there was power to the coil or to the module?:confused:

I would hate to see you spend $400 for a simple ground issue or a $20 cam sensor.

At this point if you're not going to get a multimeter to check any deeper I would head to the Dyna website and pick out something appropriate.... :2thumbs:

I used a multi meter, However the one I used did not have the RX1 on it to test the cam sensor. and like I said, When I hit run I have 12v everywhere, Just no light on Thunder heart and no spark from coil..

Yeah, Figured lol mine was working great one day then the next day nothing at all, Traced all wires including tach and still nothing.. and I have no LED so im guessing my module is just fried....Does anyone happen to have a replacement part # for cam sensor?

I Found one on fleabay for $20 from BigDogPartsKingPen, picked it up as a spare. Even has the BDM connect plug & play :up:

You can PM him on the forum if he doesn't have one up on Ebay I'm sure he's got a box full at his shop.

There is one on fleabay now he wants $30 I'm not sure who the seller is. I would go to the ebay forum and contact BigDogParts

That Module, Will not work mine has 2 plug its 3 prong 4 prong, However I contacted big dog directly they offer new sensors for 140 plug and play style, Atleast I know I have some options.. I have a few more tests to run...

What I would really like to do it is just to simplify the bikes wiring.. Perhaps aftermaket ignition and wire plus would make this dog 98% reliable lol
