Ignition unit XS650SE

Hi there,

I'm looking for an electronic schema of the electronic ignition unit of my
1983 Yamaha XS650 Special Heritage. It's a Hitachi Type TID12-03. I've
already searched the internet extensively but there is nothing to find. I
also contacted Hitachi but they do not support end users. Is there anyone
who has a schema of this ignition unit or does anyone know where I could
possibly get it?

With kind regards,

What on earth is an XS650 Special Heritage?

 

Guess what? I've got a spare Hitachi unit for one of these, only it's a
TID12-01. Can't see that it'd be much different, though: maybe just a
slightly different ignition curve or summat.

If you're looking for a working iggie unit, yes, this one does.

 

Yamaha.......

 

Hallo,

Thanks for your offer. I'm not after replacing my unit. It still works. But
I'm after the circuit diagram. I want to know how it works and in worst case
be able to reproduce it.

Please post at the bottom in this newsgroup.

Why on earth would you want to do this stuff anyway? have a look
outside, there is a world full of intersting diversions.

 

XJ600s? Nah.

 

Ba Doom Tish

 

yeah, yer right. boring as watching paint dry. I'd rather the original
XJ600, looked better made.

Mind, the 900 diversion looked more convincing.

 

which newsgroup?

 

Does the electronic unit have a built-in advance curve or does it still
depend on mechanical advance? If the latter, then it'd be a fairly easy
job to build one from scratch by copying another simple unit as used on
many bikes of that era and adjusting to suit the Yamaha ignition
pickups. I'm sure there must be schematics out there for basic ignition
units from other models.

I have an XS650, but it has mechanical advance, so I'm not sure about
later versions.

 

There's nothing like getting a nose full of solder flux and scrabbling
around under the desk for tiny pingfuckits.

 

amazon books will get you either the haynes or clymer
manuals.
if you're cheap, try yahoo support groups for a person to
email a scanned copy.

 

basically a japanese version of a bonnevill with electric
start and a hinge in the frame.

Hi Dave,

Yes, there is a built-in advance curve in this ignition. That's why I want
to know how this particular ignition works. And I agree that when there is a
mechanical advance everything is much easier because there are lots of
electronic ignition kits that can be used. Alternatively you could reinstall
the mechanical advance which is possible with all xs650 models. But that is
not what I'm looking for. I would like to know if anyone has a circuit
diagram of this ignition. Yamaha and Hitachi are not very cooperative,
although Hitachi said this device is not being manufactured anymore. Well
that's just my point.

Hi,

Good point. I already have these books. You realy need them if you want to
keep driving a bike like this. And I hapen to like it (with this particular
bike). But the workshop manuals and owner manuals hardly ever give details
about the electronics. I just want to know what parts are in this ignition.
Thats all.

there should be wiring diagrams. all my other h/c manuals
have them and a list of electrical components.
did you check carefully? also check the yahoo and google
groups. you should get much help for free.
those 650's are great bikes. i've had several from a 72 to a
80. they all had personalities and responded to carefull
maintence. vintage bikes need to be cared for and about.
i wouldn't hesitate to take a well maintained 650 cross
country and have actually done so. my ass hurt, but the bike
ran without complaint. i did a check at the end of each day
and changed the oil every 1000 miles while going x-country.
if you get stuck, lmk and i'll try to help.
ride on....

 

Hallo,

I'm afraid we are talking about two different things. Yes, of course the
wiring diagram of the XS650 is in all the books I have. I've even studied
it......... But I opened that fascinating black box with IGNITION UNIT on
it. There is a printed cicuit board in it with electronic components on it.
The intergrated circuit on this board has been made unrecognizable as well
as an other few components. I want to know what components these are. If
necessary I want to be able to repair such an ignition unit or even
reproduce one. That's why I'm looking for a circuit diagram of the
electronic ignition unit. Maybe my question was not specific enough.
Of course I googled as much as possible until my fingers hurt. But I didn't
find any information on this subject on the internet. As a member of the
Dutch Yamaha 650 Twin Club (www.xs650.nl) I get all the help I need but most
XS650 enthousiast do have a more than average mechanical knowledge of this
bike and an excessive knowledge of the electrical system of this bike
because they all like to keep them riding. But electronics is something
else. Ignition units are now over 500 dollars (NOS) in Europe and second
hand cheaper on eBay. But because this unit seems so uncomplicated I want to
know all about it. For my bike it's the most critical part because it won't
ride without it.
By the way, my bike isn't riding anyway because I stripped it totally. I'm
rebuilding it as a caferace (like so many others). That's why my ignition
unit is on my writing desk now and that's why I've opened it and that's why
I want to know............. etc.

With kind regards,

Haro
