i did some testing with a tester,i have more spark goin to negative side of coil then positive side.which i have a very little spark on that side of coil on postive,without hotwire. when i run a hotwire from the battery post on the postive side to positive of coil i have all spark on that side and none on negative. should i have spark just on the positive side and none at negative? should have i the equal aumount on both sides? what could this problem be?
