    Cheers Mick.
    There is a thick -ve cable running from battery to the frame for the hinged bonnet. Attached to this is another wire that goes to another part of the frame and that has 4/5 wires connected to it. It's these 4/5 wires that need a wiggle to get it all working at the moment. I'm assuming the issue is with the connection here, if I can get a distribution block type thing and attach it to the frame where the -ve cable bolts to that will be a more secure earth than what is currently there. If I can split them up then even better.

    Any recommendations on blocks/rails? All I have pictured in my head when I think of this sort of thing is the household connector blocks but I think I'm after something that can take a connection one end and provide an earthing point across the rest of the contacts on the block.

    Dan,

    The Eureka has the batteries up front. Both the Positive & negative feed run through very thick heavy cable to the back to the starter The earth bolts directly to the starter mounting bolt & the positive to the positive post on starter. I then use negative (Earth) bus bars that feed directly off the earth to the starter motor, (Nice thick wire) or directly to the negative post on the battery, again a nice thick feed wire. I don't trust the beam axle to make a good contact with the main chassis and advise that you also run a thick (jumper lead type thickness) from the battery negative to the main chassis & then again from the chassis to the gearbox.

    So many dull light & indicators that go off when the brake is applied & vise versa are due to poor earths.

    Good luck

    Of course, with a plastic car one can use that to your advantage. An 8mm nut and bolt through the body with a "penny' washer either side makes a good 'post for earth or power. I have three next to my fuse / relays boxes. For central consoles and dash the gear shift bolts are a good earth point too.

    Tell me about it, I've got a Corsa that resets the trip counter if you signal left..... can I find the cursed fault?
    It's a 50 year old car and everything works, just not always at the same time.......and it's probably about to get jealous!

    Obviously you need to connect one side of the post to the chassis or battery as plastic is a really bad conductor

    I always plan in earthing points on any kit putting in more than is needed.

    Typically I run large diameter battery cable from the battery to an earth bar/point at front and rear of vehicle.

    At the front the metal support bars for the steering column are ideal, at the rear on Novas I run an angle iron piece along the fuel tank support - helps reduce pressure on the GRP and gives a point to earth back to. I run battery cable to a unit like this on each location:

    https://www.google.co.uk/search?q=ea...EQV5pzed0PM%3A

    Loads of sizes available - screwfix or any electrical contractor.

    I then run earth wires back from instruments etc to this. I also run earth leads between chassis and gearbox etc and from battery to chassis.

    Agree re scotch lock comments - bin and replace with fixed connections.
    All the best,

    Jim
