Tiger Brain

[MIMbox]

Because I am Bored i did some Brain Salad Surgery ( anyone old enough for the music reference?)on my spare Tiger ECU.
If you ever wondered what was inside.

yep and the common failure of a Triumph Igniter box is the transistors that you see across the top of the board in the heat sinks
All a transistor is really is a switch , I had one fail on the 95 and it was the one that went to the #1 cylinder .It was fried so that all current was going to the coil all the time which overheated the coil and melted it

$2.55 for a new transistor from Radio Shack vs. $600 from TRiumph for a new Igniter , That was like 10 years ago .and that igniter is still working fine in Tigger #1

Most Bikes you won't have the luxury of opening up the ECU as they are sealed in epoxy resin .

I pulled mine apart as well due to the tach not ticking. Just a bit of a poke around looking for a burned trace or maybe an overheated resistor. I couldn't find anything amiss, so I buttoned er back up. Still runs great, still no tach.

Triumphs manual for tach repair. "Replace tachometer, if it still doesn't work, replace CDI unit" :roll:

No Google....

Emerson, Lake, and Palmer.  Very surreal album cover art by Giger.

Yup I have the album in the loft somewhere, it's next to my Dave Greenslade collection including the original "Pentateuach of the Cosmogeny", there is even a track on it titled "The Tiger and the Dove".

Giegers stuff is amazing but ultimately a bit scary (Sagem electronics is comparable), I'd love to see Gieger and Patrick Woodroffe colaborate on an album, weird man  :shock: pass the 'shrooms.
