Turbo 360: More potential shell ruining lol

[L14MNP]

Squeeky belt?
send it back.

No squeaks here sir. You sure it's not your old joints again?
I wonder what you hear? Like I say it is silent IRL.

Technically I could give him it back, it's all there still...

[volvosneverdie]

Second Vid, I thought I could hear a squeel when the revs drop??

Only on a one speaker laptop so its obviously an audio issue then.
Modern Technology fail, old volvo engine win!

[L14MNP]

I think i hear it now mate. It sounds like something reasonating to me. Half of it's organs are draped all over the place lol. The coil is just loose etc.

Time to dig for some wiring info.

[L14MNP]

Anyone know what this is btw (resistor?) It doesn't seem to be needed, but I just want a better understanding of things atm!

[Ride_on]

No sure about the resistor. I disconnected mine -- won't start without it!! Initial guess is item 377 Ballast resistor for injectors beside the LH2.4 control unit in the digram.

I also have the Haynes manual with wiring but have an electronics background I find it very hard to follow. I also find its not really correct in some areas and I needed to use my USB microscope to read it.

Immobiliser is just a starter motor inhibitor, recommended to replace with a relay. Not sure why you can't just jump it.

http://www.volvoforums.org.uk/showthrea ... ser&page=2

"the two terminals on the alarm / immobiliser relay for the starter motor are position B1 and B5, the wires behind the connector are pink and pink-white respectively. Remove the alarm relay and connect these two terminals up and that should allow you to start your car without the alarm. "

[L14MNP]

Ahh well my mate lost the auction for the Haynes. I need to get another from somewhere ASAP.

Yeah mate, I thought resistors for the injectors as that's what a GTi-R runs, and I needed it when I acquired the ITB's for my NA SR20. Three boxes had me like 'WTF?' though.
The way I see it, even if I don't get everything unrequired removed from the loom I can still swap it into the 360. I can't dwell on some stuff. I mean it's not as though it isn't running - then I'd be a lot more concerened what they do! lol


What a crap immobiliser then lol! I wasn't sure if it killed the coil too. It's hard to keep up when you're unplugging everything. lol Cheers for the info matey. Much appreciated. Once I chase out what's needed from the rear I will be looking at slimming the loom down, like I say I won't get everything AT< but once I have a Haynes or something from the net then hopefully I can start removing relays for headlights/seat heat etc etc.

[L14MNP]

I spent another couple hours on this tonight, sorting out more wiring BS.

Starting with a look at the relays.
I found some information and diagrams relating to the relay locations on SwedishBricks forum earlier, although my setup is still different. lol



As standard.

Simplified somewhat. Excuse the blurry pics, dunno why this one is diplaying so large!

As can be seen, only one relay is required for the engine to run. I assume I'm right in marking this as controlling the fuel injection. The car dies as soon as it removes, and obviosuly won't fire up without it.

Going from the above diagram I am thinking the relays are layed out like:

Top row (left to right)
Bulb failure
Unused
Wipers?
Unsure

Middle row:
Fuel injection the only one required
Fogs?
Flasher?
Empty (no pins)
Unused

Bottom row:
EW?
CL?
Unsure
Aux lights
Rear fog

Who knows though. Can anyone confirm this and explain the others?


Here's a close up of the ones removed if it will help ID them.


I then started chasing back and stripping out unrequired parts of the loom. SRS, seatbelt pretensioners, radio, seat heat, N/S/F door, spare plugs etc.
I am only working on one side of the loom atm and some of them loop to the other side so the rest will be removed when I get to that side.

Tonights removal. it doesn't look much in that image but there is a fair bit there, nothing compared to what is still to come out though.


Much less cluttered FTW.

As can be seen above, there is an ECU in my rubbish pile now (Bosch 0227 400 219). This is for the ABS. I have no idea why it didn't want to run the other day with it unplugged though lol. I can 100% confirm it is not needed though.
I should have trusted my judgement when working out which one it is. Failing that, it says something like Made in USA on it, as does the ABS pump.


Another massive plug and bunch of wires soon for the chop (ABS)

The wiring removed so far is surprisingly heavy (only because I never realised how much there was lol)



I had a head scratching moment earlier too. I was 100% confident of the items I was removing, so took a good few out and then tried to start the car - nothing!
The transponder chip pick up on the barrel had came unplugged lol. Happy days.


Shame I only had a couple hours for it, but it's the weekend soon and then two weeks holidays.

[griffo20022]

This is some EPIC shiznit man!

[Speedy88]

Awesome!

[L14MNP]

Cheers lads. but...

Problems!

I cut out the ABS from the loom and some other random crap, front wiper motor, door pins and one I had marked spare.

Now it won't start! This pisses me off cos I thought I was being careful with what I cut out. I'm assuming I've cut through a shared circuit somewhere? :/

I made sure it ran with the ABS ECU unplugged, it did. It ran with the ABS plug cut off, so there's no continuity required via the plug.

The other stuff I cut out was trivial. I went to fire it up and it wouldn't go. Just the starter spins. Ride_on, are you 100% that the immobilser just stops the starter circuit? Cos it means I can rule out any potential issues there.

My mate came over and we checked through the loom. The annoying thing is it isn't just a case of rejoining what I had cut. As I expected/thought. A few of the wires are nowhere to be seen :/ Yet the were all cut out from the same place. I have what was the dash loom draped over the inner wing and wa sstanding outside the car. So just working in a specific area.

As seen below.



Also, this resistor was extremely hot, and it appears that some of the coil wires run to it. (blue) I know it's on a heatsink, but it was burning hot after onlya shorthwile. Could be part of it? What does it control, more to do with the injectors? It lives on the N/S inner wing.



What colour are the coli wires where they terminate? Just incase they change (unlikely I know) Also where do they terminate?
Same questions for fuel pump. I'm not sure if its priming ATM and still can't access the wiring in the rear.
Anything else that could disable it?

It is 100% not sparking or getting power to the coil though.

I have checked the other looms too. i haven't tampered with the rear loom where it branches off from the multiplugs. Also everything on the car side of the multi plugs is intact (or as much as it was before It stopped running)

The problem has to be in the part of the loom in the first pic. I am stumped as to where some of the wires have gone though! I simply cannot account for them!

Here's the current state of play.



Damn I need a pin out!

[volvosneverdie]

Balls man.
Bad news indeed.

Hope you get back on track dude.

All those 13 million wires man.
Looks absoutley scary to me.
Like a bear has raped a car, had a rest, then raped it again.

This is no help, but at least the mental image is mildly diverting.

[340GLT]

That little unit is the ignition amplifier dude.
Adam

[L14MNP]

Oh. Cheers Adam. I'm used to those being on the head/coil pack lol.

I'm guessing it is getting power. Strange it got so hot though?


Cheers for the image Ben. There could be a bear hiding in the back tbh!

[L14MNP]

We're back on track.


I got her running again tonight and a lot more progress, during a successful four hours work.

The coil being dead was subject to one of these wires! The culprits that hid from me yesterday!


I'm not sure which yet as I have just reconnected them all. They all run directly to the ECU (not the Jetronic iirc) so fcuk knows how I ended up chopping them!

I noticed it almost straight away today after I started bunching the loom back up into some sort of order, there they were!

So with it alive and kicking again, I binned loads more stuff from the N/S engine loom, some spare plugs, the ABS plug where it connects to the pump blah blah. On the O/S there was just one ABS sensor and what looked like some sort of loop in the wiring connected by a plug.When untaped etc this turned out to be already cut, from one of my earlier useless wiring removal excercises lol. As with everything else it was removed and cut right back to the engine bay side of the multiplugs.


This fella




Chop chop


The grommets where the loom runs through the bulkhead were a right PITA to remove, with the usual mank ancient insulation tape to remove and something new. It looks and feels (and sticks to hair skin) like bitumen :/ Lovely(!)

Need a better pic. I's really stringy and sticky lol

I binned loads from the main/dashloom too, I'm not sure what they were now as I worked out I didn't need them and cut the plugs off the other night. x2 door looms and radio/heater crap I think.


All of the unrequired wires I removed (O/S) from the main/dash loom ran to the coloure plugs that plug into the yellow junction. None go directly to the Jetronic ECU

Can be seen here?


Main/dash loom - for now. MUCH more to be removed tomorrow at some stage. I also have more of already removed stuff to pull out as I have only cut some back to the car side and soem to the engine side respectively. Still need to chase up to the fuse box etc.




Yep, that is a wheel dolly rammed with tonights unwanted crap.

Bring on tomorrow! :thumb:

[volvosneverdie]

Great news man. Well done.
