Thank you for the comments and questions:
The bad circuit I mentioned here was actually the second one I found.
The first bad connection (similar with the brittle plastics) was to the alternator...
The alternator's rectifying circuit got damaged, and it may or may not, have killed the battery... voltages shot up to ±20VDC
This bad rectifier in turn allowed the voltages to spike at around 4,000PM and that got to the ECU Unit...
Then the Fuse on the Fuel Pump, ECU and Coils line blew when I was about 5 hrs from home (took me almost 20hrs to get a trailer and tow its home....)
I sorted everything out but the ECU stayed popping the fuse...
So finally I got the replacement and.....No more fuse popping!!
The package shows the key with the transponder in it.
I removed it and put it in my old key...that way I only needed to replace the HISS unit around the ignition setup, and not do a major strip down to replace the locks.
So you do't have to re-program anything... I only use 1off key in any case, as I made up shortened copies for the side boxes and such. They stay in the boxes and look like buttons, and (touch wood) so far no-one has messed with them - not realising they are keys...hehe.
Here's a link to the article on the side boxes knobs:
I saw this farkle at OH-Stoc on someones bike and thought it was a good idea. I went to Radio Shack for knobs but wasn't really happy with the knobs or the amount of work needed to turn them into key knobs so I went looking for another alternative. I found the bottle caps from certain Yamalube...

The tank is easy to replace the cap, but the ignition key set-up is not so much fun.
The HISS section is also held in-place by fancy torque bolts with centre pins in them, so you need a special torque tool to loosen.
And they don't come out all the way, but once loosened, the HISS unit can be easily removed.
I didn't have the special spanner, so I used a small sharp chisel and loosened them, then used it to retighten.
PS: I may just have to buy new keys and have them programmed/ copied off the original....
Probably better than having only one transponder (key)...
OUCH!!!
PSS: My milage is still the same 6,661.... which is 206,661kms
