Battery ground sparking when Key turned on

Hi wondering if anyone can help.. I wired everything up, what I think to be the correct way and when I turn my ignition on my battery ground sparks when moved around alittle. Is this good or bad?

However I have still not seen a spark from the sparkplugs..

thanks

Sounds like your ground is loose. Make sure it's grounded to the frame, not the battery box.

The ground on these bike's can be very tempermental. I burned up 3 charging rotor's before I found that the engine wasn't properly grounded to the frame. So definately make that ground connection as good as you can possably make it. I ended up using a foot of 4 gauge wire and went from the frame where the stock ground strap attach's to the cam chain adjuster. Not one problem with the starting/ charging system's since, and that was 5+ years ago.
BTW, the battery box is rubber mounted so you won't get a ground through that.

Yup recently got an "abandoned project" bike, TCI, no spark, no e-leg. Crude but heavy replacement wires. Everything came to life after I removed his ground strap from the battery box and moved it to the frame.... The original ground bolt was broken off and he used a conveniently located airbox bolt, oops.
Ground straps can corrode internally and turn to metal dust, a poor conductor of electricity.

Thanks everybody, I tested my coil and it seems that's my problem
