"Earth" and Tonneau bar

[Mark Stolzenburg]

A couple of questions:

1. My wiring harness has no ground wires for the headlights, fog light and front side lights. Is ground (earth) achieved only through the mounting points or is there supposed to be ground wires? Any suggestions?

2. Does anybody have the source for the screws used to mount the tonneau bar on the back of the seat? I think they are wood (?) screws that have large flat, round heads (if that makes sense). Thanks,

Mark Stolzenburg

The original harness didn't have ground wires, counting on the lamp mounts to achieve ground connections. Paint, rust, and miscellaneous grunge do bad things to that grounding path, so it's a good idea to add ground wires to all lamps that don't already have them. -- Chip Old 1948 M.G.

Nearly all cars in the world use the body for the GND return. The TC is no exception.

- Your wires connect the light bulb through the switch on the dashboard to -12V.

- The other side of the light bulb goes to the body (GND = 0V).

The only problem that could occur is: Bad electrical contact between the different metal parts (wings, chassis, etc.) due to corrosion or because of new painted parts.

Run the wires all back to the same point and thence back to the battery. Others have already said, rust paint grease, gunge, will only go to make sure that any of your electrical circuits don't work, usually when you most want them too. i.e. When it raining, cold , and dark at midnight in the middle of nowhere!! You run the risk of circuits finding a earth run through other circuits if you dont. An example would be say all the lights working but in series together, very dim. The reason that they are not there are because of absolute cost cutting when the cars were built, but then they were new, rust hadn't developed and there were few electrical problems. With care they could be fitted discretely. Safety Fast again.. (Its your life!!) Regards to all. Roger Muir -------------------- End Forwarded Message --------------------

Mark: I ran a ground wire from each headlight socket through the headlamp bracket and connected the wire using a ring connector under the nut the holds the fender to the fender stay. It works just fine, no more dim headlights. Ken TC 4147 Mark Stolzenburg wrote:
