Good thinking - I think most time delay relays give you a live output as opposed to an isolated contact so youíll perhaps need to take that output to a relay to switch your earth. Does that make...

Thomas

I feel I must defend my corner in that I know what I told you re A/H track rod ends is absolutely correct for the 408s, 409s and 410s. Given the proviso re the later A/H 3000ís.

Tracking was...

Why do you want to modify the track rods? I presume you know that the track rod ends are identical to those used on the Austin Healy 3000 - you do need to know whether you need right or left hand...
