Does the ignition warning light work properly?beefy wrote:cheers brian i just trying un work out the problem with my m30 engine not stopping do you have any more advice on this.
not sure brian will check 2moro,
hi steve yeah when i turn the ignition off the engine keeps runing, have to stop the engine by unplugging the ht lead from the coil. Some how the coil is taking power from the thin blue wire off the altenator, this thin blue wire is for the altenator warning light.
I have asked this question in my thread "m30 progress and questions"
I also think it would be good to have a sticky of the list of the wires colors and pin numbers for c101 in this forum.
