Everything in my engine bay(s) has a coppery tinge. :-) Okay. I'd not thought of that. I have probably enough for this job left over in a small sachet from the last time I did the spark plugs. > If you have corroded earths, undo the bolt, clean up the > terminals with a wire brush/emery paper, and reassemble with > generous lashings of copper grease. The cross-member earth point looked pretty bad and on close inspection, one of the wires had come loose from its hoop terminal. I unbolted the point and cleaned up all the terminals with an emery board and some glass paper. The earth point itself was actually pretty good once I got down to it and I managed to polish up about a square inch of shiny bare metal. I've put a washer at the bottom of the stack, then the battery negative, another washer, then the larger wires, another washer, the smaller wires and then another washer. So, I take it I should take it all apart again and smear everything with copper grease? Perhaps remove a couple of washers too - I probably went a bit overboard :) One at the top should be plenty. >> Okay. How/where does that earth?

I'll take a look tomorrow and rig up a couple of spares for the emergency kit. My garage recently had the alternator out to replace the bushings and the brushes. I doubt they've put it back with a dud wire, but I'll have a look anyway. Thanks again, Paul
