"Chassis Ground" points in 3.2 Carrera engine bay?
Can anyone tell me where the best, factory provided Chassis Ground and Ground point(s) are in the Carrera engine bay closest to the ignition system?
Just trying to locate the best points for an aftermarket Crane ignition system.

Documentationis much greatere for these later cars - check the Bently and factory manuals & see if they don't have a diagram and complete list. |

The chassis ground in my '86 is just ahead of (and hidden by) the coil. Follow the brown wires coming the intake for #1 cylinder and it would take you right to it I think.
What's up with the Crane ignition system? I mean what's it do that the stock system doesn't? Twin plug? -Chris

Much stronger spark at high RPM and also fires multiple sparks under 3Krpm's for better/cleaner burn & throttle response. For the Stage 3 boost levels I'm running (up to 1.25-1.3bar), the forced air is literally blowing out the spark under load and misfires are occuring.
