Hi, thanx for answering!
I have one more thing to ask
I have no spark, it happened before and when i changed the coil it worked! Now the same problem and i am wondering what could cause the problem...
Is is normal to have "short circuit", 0 resistance,
between ground (0) and the coil alimentation cable,
that comes out of the motor (and between 0 and light alimentation) ?
If not, how can i remeditate the problem?
