Im getting an intermittent start failure on my 1984 (85 Model) DG Auto
Happened again on way back from Wales
to save shorting the starter while laying underneath have run a wire up to 90 amp alternator that I just touch on battery wire and it starts every time.
Have Haynes and Bentley manuals but Bentley only shows injected models no carbs and Haynes only shows manual

Need the diagram for the red black wire from ign switch (Fitted new electrical part (Meyle fro BW) today) still not starting.
I know there is an inhibitor switch but just want to see wiring diagram if possible.
