im getting a good earth anywhere on the rad support even without the body earth hooked up to the battery! anyone know if this is normal?

horn earth may be a little hit and miss.

any takers?
Have you done the basics (checked that all terminals and fuses are clean or not blown or dirty) with the fuse box? There is also a harness earth that connects to one of the screws that holds the fuse box in. There is also an earth that connects to the steering column, is that in situ?
