One other possibility:- A crappy cheap red key battery isolator while give similar symptoms- you can rule that out bypassing the isolator by putting both cables onto one stud, if the problem stops get a decent isolator to replace the problem one. I have these. Could I please have some recommendations for replacements, I have seen people not impressed with the rotary multi position isolators (Off,1,2,both). I meant to say, Graham gave me a heads up on these :- www.amazon.co.uk/dp/B0738JGVZ9/ref=asc_df_B0738JGVZ957532273/?tag=googshopuk-21&creative=22146&creativeASIN=B0738JGVZ9&linkCode=df0&hvadid=310513207083&hvpos=1o1&hvnetw=g&hvrand=14768861029928460633&hvpone=&hvptwo=&hvqmt=&hvdev=t&hvdvcmdl=&hvlocint=&hvlocphy=1006653&hvtargid=pla-613876891872If if you fit one in conjunction with an off,1,2,both isolator it sorts out charging the batteries - all you need do is leave the domestic batteries selected, use that for everything including starting then flick over to the start battery if there isn’t enough welly to burst it into life, select domestic once it’s running and leave it to it. I've fitted several now, saved loads of messing about rewiring and sorting split charging. Particularly useful on twin engine set ups too. www.victronenergy.com/battery-isolators-and-combiners/cyrix-battery-combiners

Actually, it is a little trick that can work. As with the main isolator switch for the type of buses I drive, the contacts can gradually weld themselves to 'stick' together, so a short sharp 'encouragement' can make the difference between going somewhere or not.

Tried again this morning started perfectly fine. No clean up today though, the rain has just started! What I'm struggling to understand: If there's a poor connection I get how something might flicker or not work at all but in relation to a starter motor, how can a poor electrical connection create this this great big sound? I'd expect it to either work or not and if not, for it just to be dead. Shows how little I know I guess.

Tried to erase all the crap that appears vertically up the left hand side of the reply, and now the whole sodding lot has disappeared !
Now re-posted a bit further on.

BANG IT WITH A HAMMER AND TELL IT WHO'S BOSS! hee hee hee .... you should have heard the apoplexy on the other side when I suggested this (I actually said try giving it a sharp rap to get it running as a temporary measure to get him home) They raved and waffled on about how could I suggest that, if it was a modern starter it would shatter it's internals etc etc etc Dorks !!! If they read the posts from the start, he had posted the make of engine which meant it was an old style starter You and Ross are on the money, old style starters that play up due to sticky solenoids or brushes - a damn good smite often teaches them not to mess with the guy on the key John should have probably given the armchair experts a good smite too

I'd expect it to either work or not and if not, for it just to be dead. Shows how little I know I guess. Referring back to my earlier post, . . if you want to track down and identify what's causing the starter problems you're having then you'll have to set about it in a logical and ordered fashion, which means doing all the isolation and voltage checks I suggested for both starter and auxiliary circuits BEFORE you do any cleaning up on the connections and terminals. There is no point in trying to locate a fault AFTER doing something which could possibly have eliminated it. There is also the possibility, of course, that what has, since your first post in this thread, now apparently become an intermittent fault that fixes itself, might just be down to the engine happening to stop the last few times between cylinders 1 & 2 instead of 2 & 1, or vice versa, allowing the starter pinion to engage with a different part/section of the flywheel ring gear.
