afternoon all,

i have just give it a run for first time since fixing it and it has done the same cut out and lost its spark, i have rechecked 12v feed and it is there but the coil was red hot(brand new coil), this is going to seem like a stupid question but the 12v feed goes to the black plug should this go onto the + or - connection on the coil? if they were the wrong way round would it start??? like i said before i am no most technical person so all help would be much appreciated

thanks for looking
