82 xs400 bobber no spark

Hey guys, i have a 82 xs400 he that has no spark i checked coils at 3.5 ohms on primary couldnt get anything on either coil for secondary i ended up having bad spark boots on both sides so that might have been why havent re checked but the bike lights up and it seem like im getting power to the coils i just dont think its enough if anyone has any ideas or cheap parts itd be a great help, thanks.

You think they are getting power? I’d use a dvom and check, also check fuses and ohm our the ground connections to make sure there isn’t any resistance.

From there, you can narrow it down quite substantially, possibly even find your bad part//switch/connection. If unfamiliar with the wiring, you can check out the wiring diagrams on here and trace through them and check the spots on the bike.

Wires don’t typically have issues in the middle, it’s usually the connector section unless something melted or chafed enough to cut through.

Good fully charged battery? Grounds? I don't see the ignition box in all those wires hanging, do you have one? Could be a lot of things. Did it run before?
