i tested earth to rad support and the bolt head was pretty dead but the thread of the bolt was OK which is weird. i swapped bolt and have good earth but has not resolved any problems. earth is also good on harness at a-pillar.

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?
