    Rallye 1,3S coupe earthing

    Does anyone have clear photos showing alll the earthing locations? My car only has the battery to oil filler cable. From what I've read, there should be more??? Thanks

    S1 or S2/3 car?

    On S1 (but not the HF with alternator instead of the dynamo), there is a thick cable going from the battery to the gearbox/engine (not the oil filler), connected to one of the big screws that join the gearbox to the engine. The main connection to the chassis is supposed to go from the dynamo to the regulator, and from there with a short wire to the chassis. There is another earthing cable to connect the subframe (apparently only for providing ground to the horns) from the gearbox to the middle front leaf spring box. All other ground connections go through the chassis.

    It may be different for the cars with alternator. One thing I know for alternator equipped cars is that there should be a ground wire connecting the alternator to the engine, as the alternator is fitted using rubber bushes, and ground connection for the alternator may be unreliable without that explicit ground wire.

    To clarify, my car is a 1969 series 1 with generator.

    In that case, it is as described. I can't take pictures, because I made changes to the earthing on my Fulvia (I provided separate earthing cables instead of the chassis for about all main electrical consumers), so the pictures of my car's setup won't show you what you need.

    No worries, also my car is right hand Drive, placing the battery adjacent to the oil filler

    Oh, right. On RHD cars, the thick cable may go different indeed. The other connections are most likely as described.
