So I have 4.99 on the C, grounded it for 3 sec. and no spark..we are talking about @ the spark plug right?It does seem that if the coil is getting full power @ c & + and the ign.plug in that the coil is that bad guy ? Was that the original reason for the break down in the first place was the failing ing. coil?REplacing it with a brand new bad one...man..All these test.even if there just happen to be a bad ground would've went around some way right?Every thig seems to get power just cant get spark out of the coil!
