Ignition Coil - Sparks everywhere
I have my engine running, but today I noticed that the ignition coil seems to spark between the + and - terminals and the HT feed.
All terminals have rubber boots on, yet still seems to spark. I can only put it down to the small gap between them all.
Is this normal?
Thanks
Rob

Not normal - it's "tracking" - a HV breakdown over the surface.
If it's clean, the HV may be following a carbonised track or crack.
Clean & dry thoroughly, if it still does it it's new coil time.

PS. That's why it's a good idea to open your bonnet in the dark sometimes.

I have another coil (new) which I tried and it did the same.
I will clean and dry everything.

Fully clean Coil HT connection and HT lead connection if still tracking
Swap HT lead

normally caused by moisture,also a big gap,maybe carbon fell out of the dizzy cap,rotor resistor is popped or broken leads can cause it

Cleaned everything and dried with kitchen towel and hairdryer. It must have been due to moisture as it has now stopped "tracking".

A coil designed for use with a ballast resistor being used where no ballast resistor is present?
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Before I dried it all I was also thinking that myself. Everything was as it was in the original Sierra, but that's not to say it was right their
either.
How do I tell. What does a ballast resister look like and where does it go?
I know my new coil is for a 1.5ohm ballast resister, but not sure about the original one?
