I got my car back from my mechanic today. He fixed a fair few things.
Turns out the starter issue was down to a bad earth at the 6R4 relay up on the inner wing! The earth wire disappears into the loom, and emerges again a short distance away to attach to the top terminal of two on top of the brake fluid level sensor. That connector was loose and both it and the spade were mucky and green. New connection crimped on, a quick gleam up with some Emery paper, and the issue is banished. Shame none of the three AA guys I had called out had thought of checking that. Oh well, at least I have the peace of mind of knowing that the starter motor is once more in tip top condition, and that I have a good working spare relay.
The brake warning light that I had been ignoring (blushes with shame) thinking there was a wiring fault turns out to have been working properly, trying to tell me the front pads were worn down to the wear indicator wires. Doh! Good thing I gave the car in for a service, I wasn't far from the backing plates of the front pads! The front wheel bearings were also loose and needed re-packing and tightening to spec.
The fluid level sensor needed the contacts cleaning up, and the old cork float didn't float any more. A nice bottle of plonk provided a new cork, and some liquid comfort for the man with the spanners.
I finally have a wiper delay that functions! Yay! It had never worked in my ownership, and I had never gotten around to investigating the issue. The electrical contacts inside were all furred up with corrosion, and it had been wired up incorrectly to boot. A new piece of foam (actually it looks like a piece of a red Scotchbrite pad!) was also required. I should've done that years ago. All that frustrating having to reach up to turn the wipers on and off again whenever the rain was only slight.
The passenger side wiper blade didn't sweep the whole screen, much to the dissatisfaction of my trusty co-pilot. She'll be pleased to see where I'm taking her in the next inevitable downpour. I had fitted a replacement blade and crimped it too tightly to allow the rubber blade move. Now sorted.
The gear lever had become quite recalcitrant, and reverse was ever harder to select. Now I can engage all the gears smoothly again, snickety-snick, after the lever and remote both got a good clean up and re-adjustment. The handbrake got adjusted back to functionality at the same time, by tightening the cable.
Underneath, the prop shaft needed two new UJs. The diff extension seal was replaced, and a quick peek showed the bearing behind it to be in fine fettle. The front diff mounting bush was very knackered, so a new poly one from Winns International was fitted. At last the grinding noises from my drivetrain are now banished. Much better.
Money well spent, as the drive is a whole lot more pleasant. I can whole-heartedly recommend Graham Ransley at Brooklands Motorcraft. Knows his way around these cars, and how to keep them in proper order. Well worth driving the extra distance to his new premises in Hertfordshire, a little further from me than he used to be.
Thanks again, Graham! Great job as ever!
