oooops, I think I broke it :)

[york33]

First I'm ill for a week, then I go away for a week long Microsoft training course........and look what it made me go and do........oops





For the benefit of those who haven't guessed what was going on there. I seem to have ripped out any wire that has anything to do with the ignition/injection system. Hmmmm, now all I need to do is make a new loom and fit it back in the right place.

Who thinks she'll work when I put it all back together? Don't all shout at once!

Dave,
I was rather hoping to see a post starting with brmmmmm.
I assume you found some sort of problem before you pulled the lot out
If you intend making your own loom KEEP THE OLD ONE. Use pegboard with pegs set at distances from your old loom. Lay the new wiring onto board and wind round pegs then wrap and add terminals.
Now you can use the pegboard to hang your tools on.

NO - not first turn of the key....

I thinks you're probably right But she can't get any worse than she was before........well, she can't not work any more than before anyways!

I would have loved to have started the post with brmmmm, but alas no. Well, I found 2 problems, one obvious, one not.

First one is easy, the terminals in the ignition switch seem to be well dodgy. Waggle them and it's 50/50 if they'll output what they're supposed to when carefully balanced. Ebay has kindly found me a replacement which is on it's way I hope......

Second one is a little more troublesome. You know the big clump of connectors near the ECU? I wiggled and waggled them and once I got my sparks back, but only once, then they departed.

Got the safety switch thingy working properly and fuel pump now runs when it should. The rest is bizarre, got 12V at coil and can get plugs attached to it to spark reasonably. Might replace it anyways, just for good measure, looks original. Presumably my sparks ain't being triggered by dizzy so it's either that, its connector (which fell apart when I looked at it), the wires or connectors between bits or the ECU.

The old loom is all labelled and stretched out on my lounge floor. There's various places where the wires have worn insulation and the copper has turned green and crumbly. I'm just figuring out what new connectors and wires to order. Got to be black wires still though With labels though! quite like the pegboard idea, cheers

Dave,
All black eh,
How about a second colour for the grounds. Makes fault finding so much easier. (in the future)
Jeff

[york33]

OK, I admit to relenting slightly on that idea and will be having two colours along those lines, black and red I thinks, will see how the mood takes me

Unwrapped it last night, it's very dubious, there's random 2 metre loops to cover 30cm distance! I don't think it'll be too bad to do and hopefully worth it. Had a meter on it and wiggling bits varied the resistance of some wires from ~0 to infinite There's a random bodged one that has turned so brittle it snaps with a nice loud crack when you bend it slightly.

Wish me luck

I seem to remember that wedg1e completely rewired his ECU/injection system and posted details of his exploits here: might be worth a search.

Most importantly, he found the suppliers of the correct connectors....

Edited to add: the thread is here

ahhh, I remember that thread popping up now, cheers for the reminder It was a fine essay I was about to order from VWP so it appears I'm getting the right connectors

cheers

Hmmm. As I recall, the 2.8 injection wiring was incorporated (or partly, at any rate) into the main harness. Mine's a V8, and the loom is entirely separate (apart from about 3 or 4 connections) to the rest of the car wiring.
Even so, shouldn't be a major job Dave!

hope i am not teaching granny to suck eggs,but......try not to kink any of the wires at any stage prior to installation - thats where a lot of snags tend to be born. Any weakness prior to installation will only be accentuated over time with flexing/heat cycles and vibration.
Dunno much about the connectors - but a dab of silicone sealant (right temp grade of course) in the back where connector pins go ,prevents water ingress and therefore less 'green copper'.
High temp spiral-wrap is good for protecting cable looms and looks neat when done properly.

P.s. the pin board is a top tip (and always cut for 'a little extra' - so that trimming/repairs are possible in the future)

All egg sucking suggestions appreciated

I've ordered a load (25m) of spiral wrap for this part of the loom and for future use. Also, new connectors for the injectors and sensors and for the ECU, dizzy, etc. The ignition/injection part of the loom is largely separate to the rest. Couple of common wires to other random bits of the elastic tricks but not too bad. Also ordered some nice new earth braid for here, there and everywhere............

Just awaiting my delivery from VWP and eBay now. Should be with me by the weekend. I might even wire her up this weekend! I really, really, really, really hope she works after this. If not, I'll cry very loudly until someone comes to help me

Beware of spiral wrap ends where they are cut. Tend to cut things they are supposed to protect. Had a few problems on something else with it. Mine has a lot of flexible ducting in the engine bay. Very tidy. Black ribbed stuff.....er....plastic.......ahem....ah.. trunking.... (oh god it gets worse)

[york33]

Why is it raining, someone make it stop

Plugged part of my gorgeous new loom in late yesterday. The rest is finished too, just not attached. Bad light stopped play, but it's supposed to be alright today......

I think it's right, just got to figure out which way round 2 wires I mixed up go (oops) and get the three dizzy wires in the right order. Then I plug it all in (hopefully in the right places). Turn the key (after wiring up slightly different ignition switch) and then she'll go brmmmmmmmmmmm............ha ha ha, yeah right

Hmmm, I'll leave you to your ribbed things the spiral stuff is a bit sharp, but don't worry, I'll use protection........

You think you have problems... I was supposed to be fitting the handsfree system for the mobile phone into the van today, but I fell through the lounge ceiling and sprained my toes. Can hardly bloody walk, never mind fiddle with car electrics!

Ian

[york33]

Hmmmm, you're not supposed to laugh when people hurt themselves are you However, I believe that I can make an exception in this case

So, driving down here and fitting my new engine loom in my car for me in the pouring rain isn't going to happen then

Hope your toes get better soon......

[york33]

I suppose this is called kama as a result of my earlier comments!

I have spares! Arses! B%%%x! They're carefully labelled in my engine bay as A and B which I'm sure used to correspond to an A and B on the wires I removed. No longer, no I don't understand how or why either! I have one wire in my wiring loom which I think connects to one of them, both A+B seemingly going to the starter!

Then I started having doubts about some of my others and then decided they were wrong too!

Sure they're not and it's just me being moody so I've come in to have a whinge

Aaaaaaaaaaarghhhhhhhhhhhh..........
