Re: Ignition Fault.....Somewhere!
With Regards to earthing , I always run a braided earthing strap bolted to the bell housing and the other end directly onto the negative terminal of the battery.
they are available in different widths and lengths e.g https://www.ebay.co.uk/itm/Car-Engin...MAAOSwl8VdljSE
That type of earthing strap will help with using the starter to crank the engine, as well as improve the intensity of the spark to the plugs.
Because they don't have insulation on here are some of the advantages:
1) The condition of the cable can be clearly seen and monitored.
2) They are very flexible , so provided the correct length is selected are unlikely to be damaged by engine vibration and movement.
3) When either charging your battery or using an ignition timing light they are a handy place to use the crocodile clips on for your negative connection.
With Regards to Scotty's car issue , as he has an intermittent fault that appears to be related to items when using the ignition, it may be possible that there is a connecting plug that joins the loom after the ignition switch possibly behind or under the dash. So that should also be checked. It may simply be a corroded connector that needs unplugging and spraying with contact cleaner considering the age of the car.
All Marlins are individually built and how the car was wired can vary greatly, so in reality nothing can be ruled out as to the cause, but agreed earthing is the starting point.
Interestingly when I rebuilt my Roadster it had quite a few problems with the electrics and of the 8 problems only 1 of them was earth related.
For that earthing problem I added a smaller sized braided strap that took an M6 bolt, from the wiper motor casing to the metal body work to increase the wiper speed.
