I been having problems with the bike turning over and it looks like the battery, I am getting a replacement from braille sometime soon I hope.

I charged another battery and the red light on the module that says thunder heart does not go on but it turns over and does not start?

I read post hear saying its probably the cam sensor , does that sound right and what and where is a cam sensor and if that's what it is where would I get one?

Im getting kind of tired of all this just want to get it all squared away please help if you can? :bang:

You can buy a cam sensor at your local Harley dealer. Pull your old one and bring it in to match it up. It's located in the cam chest lower right side of the motor has a round cover thats secured with two screws. Make sure you disconnect your battery terminals first...

Thanks for the picture and also the link, I took that cover off and there was 2 screws holding the disk with the sensor so I took that off and there it was it was marked 4803 unlike the one on ebay 2903 0r 3903 but they look the same , I dont know how to remove to wire from the motor do I have to take that whole casing off as well

By the way the plastic part of the sensor has a 3/8 inch crack in it?
