Triumph TT600 - Misfiring - we have a diagnosis!

[Blau Zedong]

Jesus christ, it looks like some of my wiring attempts in the bad old days before I learnt to do things properly.

If a garage wired the reg / rec they want bumming.

TC yeah, i'll be posting up asking how to test it. Long time since i've done wiring... let's hope i can still crimp the wires

Need to get my hands on some heat-shrink too.

I'll shout up on here once i've got the meter and test to see where the problem is.

Blue, i know. it's a wonder the bike's managed the 2000 miles i've put on it.

I had charging problems with my speed 4, i ended up replacing the whole lot in the end.

The standard wiring (or specifically the multi plug from the stator wires) is'nt great, and not really up to the job, so god knows how the dodgy rewire has affected it.

You are doing the right thing though by replacing the whole lot, hopefully it will cure your problems.

That 'spare' connector plug? They all have that, and i never worked it out either.

[Casper]

Mind and label the connections as you take it apart. saves a lot of head scratching.

When my gen and reg/rec fooked up i was given this doc to check parts.

[Casper]

Ok. Document want attatch. Ill e mail it in a mo if not attatched to this post.

[dextersaurus]

Cheers dude

Yeah, will NOT make that mistake again. absolute nightmare last time.

Cheers for the document, i'll follow that

Dunc

[dextersaurus]

Right.

So now i have:

New rear end of the wiring loom, need to cut and crimp the new bit to the old front end on the old one.

STILL waiting on the stator coil. shouldn't be long now.

Also got me a nice multimeter that i'll put to use... How do i check this reg/rec, since i dunno what it's off and what connections are what, with the dodgy wiring?

Oh, also got a paddock stand to get the rear wheel off. Woo for no centre stand.

SOON!

YELLOW WIRES: ALTERNATOR INPUT

BLACK WIRE: NEGATIVE OUTPUT

RED WIRE: POSITIVE OUTPUT

Just not sure if red is direct to battery.

[dextersaurus]

Righto.

I want to say I made good progress today, but I don't think I did.

Anyway, started with this

https://a6.sphotos.ak.fbcdn.net/hphotos-ak-snc6/249336_1886922746533_1645368025_1775436_6546518_n.jpg

Then 5 minutes later it was like this.

https://a5.sphotos.ak.fbcdn.net/hphotos-ak-ash4/247826_1904801473490_1645368025_1802123_5754548_n.jpg

Remember the state of the wiring on the reg/rec?
https://i624.photobucket.com/albums/tt325/duncdmc/DSCF0986.jpg?t=1305733581

I took it off and pulled the wiring, check the corrosion on this.
https://a2.sphotos.ak.fbcdn.net/hphotos-ak-ash4/246944_1905366287610_1645368025_1802764_3335028_n.jpg

And this left the wires a tad too short.
https://a8.sphotos.ak.fbcdn.net/hphotos-ak-ash4/252572_1905367327636_1645368025_1802765_3058900_n.jpg

So i set to work sorting out that mess of wiring...
https://a8.sphotos.ak.fbcdn.net/hphotos-ak-ash4/252499_1904948477165_1645368025_1802269_8103759_n.jpg

While waiting on the old man getting back with my tea i gave the fairings a quick scrub...
https://a6.sphotos.ak.fbcdn.net/hphotos-ak-ash4/251033_1905367687645_1645368025_1802766_4295594_n.jpg

Then joined the new half loom to the front of the old loom.
https://a5.sphotos.ak.fbcdn.net/hphotos-ak-snc6/248616_1905369687695_1645368025_1802769_6084128_n.jpg
https://a2.sphotos.ak.fbcdn.net/hphotos-ak-snc6/246637_1905370047704_1645368025_1802770_2760877_n.jpg

Then stuck the loom in the bike. This was a nightmare, i've still got one or two bits left to do, but the rain came down so had to cover her up and leave her for the night.

Hopefully get more done tomorrow... Ignition turns on now, dash lights up the like. just gonna finish the wiring, stick the tank and airbox on and see if it fires up, and how it runs.

Dunk, I hope they are not inline crimps I see in your photo

They are.

When i can get my hands on some heatshrink i'll solder/heatshrink them, but i need to get it running to test everything. long as it works for the time being, i'm happy.

Dunc

[Fortuna]

The reg/rec mod is quite a sound and decent mod...if done correctly.
I weep
Never should those connections from the alternator be spade.

[heehaw]

[dextersaurus]

I'd rather none of the connections were spade if i'm honest. As i've said, this bike was taken to an ELECTRICIAN who worked on it for a good few months to sort the problems.

I'm a 19 year old noob, and i can do a better job than that with limited tools and materials.

heehaw, you can always tell when someone's from the west coast of Scotland

Remember that program I told you about last night Dunc? Download it and buy the cable then you can put a new map on yourself. IIRC when my dad put a new map on his about 3 years ago it cost him £12. The cable cost £12 then you can do it yourself. You can also edit the maps.

[dextersaurus]

Right so now i've got it running.

When it's cold, it runs fine. auto choke comes on, runs fine, pulls fine...

Then when it warms up, it starts misfiring. EML is on, so it must be something.

Ideas?

Dunc

[chris-red]

Buy that cable so you can find out what error code it is throwing

[dextersaurus]

I have no money and no job anymore, so i'll need to wait till i get some to afford that. i know it's cheap but still

If i can get some ideas as to what it could be... I could get it sorted. if not, i'l just buy the cable next week.

Dunc

[chris-red]

The only thing I would do would be to go over the loom and check each connector, but for the sake of £12 I would rather be told exactly what the fault is so you can go straight to the issue.

[chris-red]

Do you have the service manual? I have a copy somewhere and will dig it out if required.

[dextersaurus]

Yeah, i've got a copy of it on the computer.

I'd rather spend the money on that too, but with 5 days pay for the 6 weeks work i've done, it's really got to last me 10 weeks. So anything to save money eh

Dunc

[dextersaurus]

Did a wee bit more work today. Now i'm REALLY confused.

Took the tank off and the airbox was sitting off the intakes. so i had to re-seat that as the strap has snapped, and tied it down temp with some string.

The Engine Management light is now OFF.

Still misfiring.

Took it all back off again, and changed the plugs and checked all the ignition packs for a spark, which i have.

New plugs in, packs back on, airbox on PROPERLY.

Checked the obvious connections.

took about 40 seconds to fire up. Spluttered a few times but it wouldn't start, then with a couple more shots on the starter it gradually fired up... sounded like it started on one cylinder, then another, then another, then the other.

At this point it was still reading about 60 on the coolant temp.

So i've sorted the airbox, changed plugs, i have an okay spark, and i've checked the connections.

What else could it be?

A bad earth?

Dunc

[chris-red]

Not mega relevant, but the battery strap and the airbox strap are identical.

[dextersaurus]

See, i'd have found that very useful if both hadn't snapped

i'm betting that all these problems are just caused by duff petrol, and that when i fill up tomorrow it'll start running fine again.

Bloody thing.

As long as it gets me to this interview i'm happy. it can break down on the way back, i don't care. that's what breakdown cover is for.

Dunc

[dextersaurus]

Righto, bit of news.

Decided to change the oil today, and checked the dipstick for the first time in a while.

It was WAY past the max mark.

So I emptied the sump, and out came over 6 litres of the stuff. filled one oil can to the brim, and a wee bit more into another one.

Thing is, it was absolutely stinking of petrol, so something's up.

I thought to start with that i'd holed a piston or broke rings or something, so checked the compression on each cylinder, and (from what i could tell from my smashed compression gauge) it was pushing out about 140-150psi. Probably more though, i'm not sure. but i know it's over 100psi so that's good.

Anyway. put it all back together again, gave the plugs a clean up before sticking them back in...

With the new oil in the engine is a bit quieter, but it's still misfiring like a mofo.

One thing i did notice is that there is a bit of a fuel leak from the quick release fuel lines on the bottom of the fuel tank. it's got the plastic female adaptors on the bottom of the tank, and metallic male connectors on the fuel line. i've had to seal them up myself due to the leak onto the hot engine, so i'm thinking this might be contributing to it. I'll have to take the fuel and injector pumps off the bike and give it a proper clean up, there's something really not right and i have no idea what it is
