XF Coil Query

What function does the capacitor(?) have that grounds the 'oil' type coil on an XF?

I'm pretty sure I just killed it for the second time (already changed it after it died last time) whilst adjusting the timing and am wondering if I could just ground it directly.

Here's a pic of it:

Thats a noise suppressor isn't it???

Do you have any engine noise coming thorugh your radio? If not then maybe you don't need to worry about it.

I could be wrong though....

Yep noise/radio suppressor. With the charging & discharging of the coil it stops interference to the radio

Well I just figured out it is still needed when the wire I used to ground the coil directly with melted when I turned the key.

Guess I need another one now :dead:

Thumbs up

You dont need a connection between the coil positive and earth at all. The Capacitor allows a path to earth for the AC generated by the coil but presents an open circuit to DC. Therefore if you take it off altogethr the noise supression doesnt work but everything else does.

Well just tried it again without it and still no spark. This capacitor was the only thing that ended up being different last time after trying several other coils, coil leads etc etc.

About the only other thing I can remember doing that might have effected it was unbolting, removing then re-installing the computer. Perhaps while adjusting the timing I have caused the ECU to stop working and taking it out has reset it???

Any and all ideas welcome here.

Have you got any power in the car? like dash lights, radio, or headlights??
