Alright, the new part arrived and has been installed without issue. The car starts up much faster now.
Upon inspection of the old membrane, I noticed a very small tear on the outermost edge. Proba ... |

| Thanks Paul, you're a life saver. I'll change the membrane and cover (220$ difference seems worth the challenge) and will report back. |

Thank you!
Is it advisable to start by simply cleaning out the oil trap under the valve, to see if that helps in any way? |

UPDATE
So after going through all the steps suggested by the members of this forum, the vehicle has reliably cranks 100% of the time. I've put on around 12,000kms since then. However, the crank tim ... |

I thought the positive battery cable ran from the battery directly to the starter: https://www.jaguarparts.com/oem-parts/land-rover-positive-cable-lr017335
But I've seen mention that the alternato ... |

Very interesting, Lightwater. Thanks for explaining that.
The 280 amps in your scenario represents the draw of the starter, or the total draw on the battery?
I'm mostly confused by the fact that ... |

| Right, but only a fraction of that could get to the starter without damaging a 4 gauge cable, I'd think. |

Those are massive amperages! 
My starter motor is supposedly 1.7kw, so I'd imagine it should only draw around 150amps.
I wonder what gauge cable your neighbors Audi is using that can han ... |

It could be. I used one of the starter motor mounting bolts. Mine was a manual gearbox so might not have had the bolt that Jules with his auto box had available.
Yes that's what I've done as well. ... |

| Have you checked to see if it's getting the correct amperage. You can get 12 volts on a single strand of wire but it won't carry the required amps. I can't remember what it should be but that is why I ... |

I would first check starter motor connections and engine earth/s and make sure they are pristine, as the starter motor is seriously impeded by a dirty high resistance connection.

Thanks for the constructive comment.
There was/is a lot of advice coming my way, and I'm not always able to tell the wheat from the chaff. I have nearly 0 mechanical knowledge so I'm learning on the ... |
