Occationaly e-bay comes up with some finds and I reckon this is one of them .... a 3TJ service manual in the original Yamaha folder.
Best of all it has an electrics diagram in colour. The paper is thin so I'll have to find a sheet of black paper and it will take a bit of time before I've scanned it but a clean pdf copy is on the cards

woo hoo!

well done mate. want me to stick it in the doc lib ?

Yup but probably wait till I've copied it

Well it's scanned and put together with bookmarks but it's 42 mb (37mb zipped) so I can't e-mail it.
I have just noticed a "large file" thingy in Yahoo which I assume is a file sharing thing.

It's a 3TJ2 SP Sevice Information so it really just gives data it's not a tear down and assembly manual.

Let me know if you want a copy by PM ing me your email.

Well Done Evil.... Thats spot on just that i needed
