TCI needed

[Squidley]

Hey Folks,

Dave Pankow can't seem to get a break with his 1st gens. I am helping him work on a no spark issue and it's looking like it's a TCI or in his case being a '90 VR a DCI. It appears that '90 was when they went to the different control system for the spark, so anything before '90 wont work on his bike. MICarl has been helping us with this problem and is of the belief also that this may be the culprit.

What I need to know if some of you pack rats out there have a good spare TCI (DCI) that we can test his bike against. This would only be to verify if in fact this is the problem, if anyone can help him out it would be greatly appreciated. You can PM me or Dave (Jus monkeyin around) and let us know...Thanks in advance

[MiCarl]

To elaborate: He needs a 90-93 ignition module.

I can't say I'm quite ready to give up parts yet but keep me in mind if you can't find anything else

Thanks Matt,

Were still in the testing phase and need a good TCI to troubleshoot Daves bike. If we narrow the problem to it, then we'll have to start to search out a good used one to install on his bike.

there's a junk yard that I found in peoria that has two school busses filled with random venture parts. I wouldn't have any clue what to look for, but if someone around this area would, I'd be happy to take 'em to the treasure trove to dig one out.

That sounds interesting.

hey squid,

just sent mmicarl a pm as to what my tci box of my 91 is doing. Muffinman has it at the present time but he was also sent a pm to turn it over to you guys for your testing. It does have a problem with not working the tach( thats how I ended up with one out of muffimans 92) but it would fire my bike and I wqas able to run it without the tach and it had a slight surge until you got it into the higher rpms. Hope it helps. Carl pm'd mer back and said he thought it would at least give you a starting poinbt.

Russ, if there are any in those buses you should get them. Darn things are rather scarce.

 

Anybody want to give Russ the number off one? I think it'll start with 3JJ-

Get me a part number and a picture of what to look for and I'll go dig for it. Among the things I saw last time I was in there: Markland passenger armrests, radiator shroud, ton of wiring harnesses, saddlebags, trunk parts, exhausts, radio parts, amps, oil filters, fairing parts, driver's backrest (with embossed Venture "V")...

 

Maybe I should plan a M&E (if I get my bike fixed) and plan a trip to the junkyard as part of it... but can't really ride bikes up in there. rough road and misc stuff scattered all over. would be easy to pick up something in a tire.

The '90-'93 uses the 3JJ-82305-11-00 igniter unit.

 

Earlier units (except 83) use the 41R-82305-11-00

 

They will be embosed on the top.

 

Plus the early units have an 6 pin and 8 pin connector and the

'90-'93 probably has a smaller one for the 6 pin...(inputs)

 

Here's what the 84-89 look like though.

90 -93 tci looks exactly the same with the same picups. Ask me how I know. Only diffewrence I've found is the sticker with the parts number is yellow on the 90-93 and black on the 837 84.

Thanks David,

I know that Dave is going outta his mind not being able to ride, and I dont blame him. Do appreciate all your help with this

No prob there squidley,

I just hope it works out for you guys.

I'm thinking, if the P/N of the Pick Up coil, and the " Ignition coils " are the same, and if there is NO difference in the wireing diagrams, from the 90's and later ---

 

Then it seems like the pre 90 TCI should work.

 

Maby the only difference, is internally in the Box.

 

Compare the wireing diagrams, and P/N's, if TCI P/N is the only thing that is different, you should be able to install a Pre 90 unit.

 

??? just speculating here.

[painterman67]

didnt quite follow the technical side of that geaorge , but I bought a working tci out of an 88 and although it hooked wright up all it would do is turn the bike over. No spark. Mine is a 91 . Put in a tci from a 92 and she fired wright up.

 

David

[GeorgeS]

Well then there must be some difference in the wireing, or PickUp coils ??

 

I would have to get the Specific, Schematics, for the different years, and compare them. Which I do not have at this point. My Sevice manual has a publishing date of 1989.

 

Also, maby pulling up P/N for the V-Max bikes from 89 and on, and compareing.

Might be some TCI units from V-Max that would work, just speculating ??

 

IF so, then watching for used TCI units from a V-Max on E-bay, might turn up the P/N that is needed for this bike. Again, just speculating.

Now thats not a bad idea think I'll go check

[Dano]

Well, include me in on this boat. My TCI just crashed on cylinders #1 & 2. Guess I'm hunting also.

A pre '90 won't work in a '90 and later Bike. They used a double(in Fact four Coils in two Casings) Pickup on the early Bikes and a single Pickup Coil on the later Units. Also the Flywheels are different between the Years.

 

Regarding the Vmax Units, in Theory, a fitting TCI (Year depending, same Years on the switch) from a Vmax should work in a Venture because the Wireing and the Vacuum Sensors are the same, but this is still unconfirmed. I have several Vmax Units lying around, but never came to testing one of these in a Venture.

[MiCarl]

I've cross referenced the part and the 90-93 igniter is unique to the Venture. That's not to say a Vmax igniter won't plug up and run but I'd bet the advance curve is different.

[Squeeze]

... That's not to say a Vmax igniter won't plug up and run but I'd bet the advance curve is different.

 

 

IF a Venture would run with the Vmax TCI, the Spark Advance sure would give it a bit more Power. Nothing you'd brag about, some Folks even wouldn't notice it, but if it would work, we'd have another Option for used Parts.

Pre 1990 utilized a TCI (Transistor Controlled Ignition). It utilized analog electronics to control the advance curve. It's essentially 4 units in one, with 4 pick up coils and 4 sets of circuitry in the box to fire each of the four coils. This is why when the TCI fails it often only looses one cylinder - very few of the components are shared.

 

From 1990 on Yamaha used a DCI (Digitally Controlled Ignition). There is one pick up coil which is watched by a microprocessor. The microprocessor then calculates itnition timing advance and position of the crankshaft and triggers each of the four coils based on it's calculations.

 

There is very little difference in the wiring schematic - primarily the loss of the wires from the three pick up coils which were dropped in 1990. Of course Yamaha used the same connectors but moved the wires around in them so that putting in the wrong igniter blows fuses.

I'll head over and dig through to see if they've got any of these in the busses. probably wont' be able to get over there until thursday, though.

If you just happen to see any 2nd gen or tour deluxe hard bags:fingers-crossed-emo would you please let me know.

Thanks!!!

I don't have it in front of me (it's at the shop) but I believe the one I yanked out of an 88 yesterday has 41R-11 on the blue field of the label followed by a 4 or 5 digit number embossed in a silver box. I suspect the 82305 portion of the part number designates it as an igniter and is therefore irrelevant on the box itself. The digits in the silver box are probably a serial number for the box.

 

I'd expect the 90-93 box to have 3JJ-11 in the blue field of the box. By the way, that part was superseded with the 3JJ-82305-12-00 unit. So if you find one labeled 3JJ-12 take it, it's the more gooder box.
