Default Re: What is happening

Let's have a look at the non functional full throttle kickdown.

Having done a bit of research I discovered that the kickdown system is meant to be triggered by a microswitch on the throttle cable right next to the throttle cable tower.

The way it works is that when the throttle itself hits the stop at full travel, if you press the pedal further it then pulls the sheath of the cable back against a strong spring, which then acts against a microswitch.

This relies on the cable being pretty much perfectly adjusted to get sufficient travel to activate the switch...and sure enough mine wasn't even close. It's a quick and easy thing to adjust though (probably the only easy to access adjustment in the whole engine bay!), so was a quick matter to correct that.

Sadly it hasn't apparently resolved the issue, though I've yet to confirm the switch itself is working (they're apparently not particularly reliable) as the meter was making a bid for freedom the moment I let go of it because of the wind. I gave up when the bonnet blew shut on me for the second time.

If that switch is working, there's a deeper issue...but I'm not going to worry too much about it just now. It really doesn't affect the driveability of the car (the normal "mild" kickdown feature works fine, it's just the "kick in the pants" mode that is acting up). On a car with more mild power availability it might be more of a headache.

Something a bit less involved needing looked at is the state of the wood trim. It's the first thing people notice in the car.

The wood itself actually looks to be in good nick. It's just the lacquer layer that's peeling off - not unlike a Dante Red Citroen!

I've never dealt with anything like this but have a rough plan of attack in mind. The bit I'm expecting to be the biggest headache by far is physically detaching the bits of trim from the car so I can work on them.

Probably the trickiest bit with regards to the actual wood I reckon will be getting the remains of the old lacquer off. I'm not expecting it to just peel off nicely, and will probably have to get some paint stripper involved. I don't think sanding is an option as I reckon because it's patchy it would leave high and low spots...also I don't know how thick the veneer is and really don't want to risk rubbing through it.

Once I've got rid of the old manky lacquer it should be pretty simple I think. Quick coat of stain to give it some colour, a skim over with some really gentle sandpaper to key the surface, then a load of light coats of clear coat. I believe polyurethane varnish is normally used commercially...though part of me is wondering if normal automotive clear coat could be used? Both because it removes the requirement for brush painting (which I hate) and I have it in stock in the garage.

Open to suggestions from folks who actually know what they're doing there as this is a bit of a new challenge for the first car I've had with actual wood trim for one thing!

I mentioned a couple of days ago that the lights in the boot which I had revived were pretty pathetic. Having a rummage through the box of "misc automotive bulbs" this morning I came across a couple of 5W LED festoon lamps which I'd stuffed in there a couple of years ago. They're a horrible 6000K bluish colour, which is why I had just stuffed them in the box and forgotten. However for a boot light I'm not so bothered about the colour temperature as it's purely practical.

With the first one in the difference in brightness is immediately obvious! The one on the left is barely even visible.

Reckon that will be a bit more useful when digging things out in the dead of night.

Hopefully the weather tomorrow will be slightly less ridiculous and I can get a couple more things done.

The brake judder should soon be sorted as a set of discs has been ordered. Was braced for eye watering prices but they weren't too bad, can't remember exactly what the number was, but I think the pair of discs and pads was around £100. Was bracing for several times that. Will be nice to get that done as it's really the only thing that's really obviously amiss from the driver's seat to be honest.
