Under Bonnet info

Under Bonnet info - 29/09/2017 15:49

Info required please.
My car has a plunger switch to the RHS of the rad, looking at it. It is actuated by the bonnet opening.
What does it do? I can see no sign of an under bonnet light. If it should have one, where should it be?
Also does the bonnet have a front edge rubber seal? It looks like it should.
Thanks in anticipation!!

The plunger switch is part of the alarm system - there is no under-bonnet light

Yes, there should be a small rubber seal along part of the front edge of the bonnet

Thanks Nigel.
Please excuse my ignorance, I've only had the car a couple of weeks and trying to tidy it up under the bonnet.
I can see a small rivet at each side of the bonnet on the lip which tucks under. I guess these held the rubber. How far did the strips go from each end and were they there to just keep water from the side lights.

The small rivets on the corners of the bonnet are to hold two small rubber "quarter-circles" - not entirely sure what these are for - either to help seal the bonnet against the bumper, or maybe just to stop it rubbing the corner of the bonnet against the plastic

The bonnet seal is a very shallow seal that runs for maybe 600mm along the centre of the bonnet, roughly on top of the radiator. It doesn't extend as far outwards as the headlamps. I'm guessing that this seal was to reduce water ingress into the engine bay and also to help direct airflow down to the radiator

Thanks Nigel,
I can sort that OK now. I've also noticed that the headlamp wiring and plugs are covered in crap, also the side light adjusting mech, so I might just put a short strip over them as well as the center.
What does any body think about going all the way across?
Still got a long way to go yet. Definitely needs a belly pan, but that will have to wait until i can find one.
Shifted about a dozen mixed rusty roofing bolts and allen screws today from around the side lights, rad fixings, and washer bottle. Noticed the cam belt cover was attached with random scrap bolts, all different lengths and types!
One other question. what is that thing called that is connected to the center of the dizzy cover. Is it a new fangled type of coil. If so why do you think my car has got two of them?

Can't really remember much about my 16v - can you post a photo?

OK Nigel,
This Thing must be on the 20VT as well. The wire, (ignition lead) comes out of the center of the dizzycap and heads, on old cars, to what would be the ignition coil. Could this be a modern version of an ignition coil?
Hopefully I will eventually master posting pics on this site. Not got there yet!
Thanks any way

20vt has individual "coil-on-plugs"

If I remember correctly, the 16v has a cylindrical coil on the bulkhead with a lead to the center of the dizzy cap

The 16v NA (16VT is different) has a cam position sensor on the distributor, on the exhaust cam at the battery end. The centre lead (king lead) goes to the ignition coil which is part of the amplifier unit, fitted on the front of the battery tray.

You definitely shouldn't have two of them on a 16NA, and the 16VT has no distributor, just the cam position sensor (and two wasted spark amplifier/coil units mounted on the inlet manifold by the bulkhead).

Photos required please, so we can be certain what you've got.

Thanks Guys for bearing with me on this. I must try harder to get to post pics!
OK Barnacle I think we are getting near. This car is a '95 16v NA. The center lead from the dizzy on the end of the exhaust cam goes to the coil, which does not look like any coil I've ever seen before, but hey what do I know!. Coils are about 120mm long and 50mm dia on my other cars! This thing looks like part of a National Grid Substation!
From this coil there is a lead, as stated to the dizzy. The other lead is a multi pin plug.
This is bolted to the battery box. Another one of these coils? is placed below this one. It looks a proper bodge up because of the roofing bolts and second hand meccano holding it on, but the lead to the coil is missing on the lower one, so is not doing any thing.. So I guess this poor car has been bodged here and I should just have one only, the original probably being faulty, but who knows!
I'll get a pic on!

You can see the two coil thingy's in the pic!

Yep, that's been bodged...

Re: Under Bonnet info - 02/10/2017 16:05

OK Barnacle. The whole engine bay is bodged!! I guess that the top one has been added because the bottom one is defunct. I'll strip it out eventually after I've cleaned up the mess.
In the mean time i reckon I need one of those manuals in your signature, and start looking for some parts.
Weird how people are. The body is as mint as it could be and it came complete with a purpose made cover and at least £2000 worth of wheels and tyres. The motor runs sweet with good oil pressure, but does use a drop! Cam box leaks oil of course. Bits of rubber gasket and white silicone hanging out of the edges! Oil pressure switch wires about 50mm off the floor!!

I'd take a picture of mine in that section but my garage door had a battery die in it, and I won't have one for a day or two, and it takes about three hundred turns of the manual handle to open and close it... tongue

I think you can see what a stock bay looks like in my inline thermostat how to and the ignition coil top is just visible

Re: Under Bonnet info - 13/10/2017 16:15

BBR sorry could not find your pic. Any way sorted it. Coil must have packed up under previous ownership. Genuine part with ignition module £230, Cheapo coil only £23 so leave old one in place with module and bodge on cheapo piggy back with roofing bolts!!!

Re: Under Bonnet info - 13/10/2017 18:14

They come in handy sometimes don't they those roofing bolts :-)

Glad you got it sorted

Re: Under Bonnet info - 13/10/2017 18:20

It's the second to last pic in my HowTo
To be honest you can only just see the coil top next to the battery tray

Re: Under Bonnet info - 14/10/2017 15:44

It has got even better! I stripped both coils off the car and dismantled every thing. I then drilled out the rivets holding the fixing brackets to the cheapo. Undid the screws holding the duff coil to the aluminium heat soak and hey presto the cheapo was an exact replacement fit. Nice tidy job and saved £230!
