Um yeah i'll check that, the module has 3 wires that goto it, it has one 12v live that comes from igition and then from the battery only live when ignition is on, one in the middle which is earth i think, and a green wire that goes from the module to the coil, (havn't checked the voltage on these yet since fathers gone of with his meter.

The live is working fine since it puts out voltage when the igition is switched on, i havn't check the earth yet, or the Green wire that goes from the module to the coil, but i would have fought they would be ok,

Does the module put 12v down the green wire to calaspe the coil or does it earth the green wire,

um so i just remove the module and put a meter across the connertors and it should give 0.5v rising, i don't have to turn the engine or dizzy do i.

Cheers for the reply dean and more info would be apricheated
