Hi bill .. i have just bought a cs-5 coil and it seems ok,but i have it attached to my edge and have taken it to parks and tot lots where all my other coils groundbalance successfully,no problem..how ever,i cant seem to get a successful gb with the cs 5 most of the time,in fact 1 in 30 tries to be exact ..is there a prob with my coil,or is this a common thing?..yes i have gb,d in clean area etc..any ideas,bill? thanks
