How do I check a TRE ? 5th or 6th ?

[Tony Nitrous]

Just got my hands on a plug-in TRE today for the Busa.
(made by jsdproducts)
Can't say I notice anything with a quick spin around the block.

My Question is.....
I now find out there are two models of TRE.
JSD-1 and 2 for GSXR1000 and Busa
(Fixed 5th gear signal)
and JSD-1A and 2A for GSXR 6 / 7 and TL1000R
(Fixed 6th gear signal)

The TRE has no mark's or numbers on it anywhere.
How do I know if I have been sold the right one ?

Doing the clutch in / out / in / out at 2000rpm causes the rev's to drop / rise by about 500 which I have been told means its working.

OK, so its working, but is it now thinking its in 5th (which is what I want) or in 6th (which is restricted on a Busa)

Can I check with a multi-meter / 'lecky tester ?
I think a 5th gear Busa signal shopuld be 6.8ohm at the pink "gear indicator" wire ?

HELP....

OK, I just found out it is the 6.8k ohm resister that deresticts Busa's in 1st, 2nd and Top gears.

And that a GSXR6 / 7 and TL1000R de-restictor is 15k ohm,

Can i test mine just buy getting an auto-electician to put a meter on it ? or is there any other way of telling....
NO ! I dont want to see if it holds back at 300kph !!! (just yet)

run a multimeter over the wires, if an input plus output = 6.8ko then you've got the right one.

an electrician would do it in a sec.

or get one from Dick Smith for $15, it'll do. Make sure that you set it to the correct range though, on a Digitor cheapy you would set it to Ohms @ 200 (not 200 k) which is the lowest range settings for Ohms (resistance).

How many wires on the TRE (and color)?

Little plug in box that does the same as this...

http://www.wardsweb.org/busa/hayabusa_mods_tre.html

3 in and out.

Just need to go get a meter and work out if I test through the Box or across the pink / black at one end ?

My problem is its Saturday, 4.56am and I have a long day at work !

Thanks.

No probs mate, check the resistance between the pink and the other two wires. it could be either the green or black. One of them should give you you're resistance rating.

Thanks,
Good advise.............

Went to Super-Cheap today ( 'cos I was working next door )
Bought a cheap multi-meter for $13, never owned one before.
Read instructions.
Went home.
Off with the seat (2 screws)
Off with the tank (2 screws)
2 or 3 minutes at the most,
(My favourite Suzuki dealer wanted $45 to do this!)
Unpluged TRE,
Tested across the Pink and Black terminals of the TRE on the loom side, not the gearbox side, and.........

6.8ohm

Spot on what it should be.

Tony is now a happy little bunny that its in, fitted, and working, and he knows it IS the right one.
Not so happy that it doesnt seem to do much, I was expecting more or a differance in 1st and 2nd.

O-well, live and learn.

Still needs more power,
LOT'S MORE POWER !!!

You Sure ?
My meter says.....

2000K
200K
20K
2000
200

I get no reading at all on "200"
but get a spot on 6.8 reading on the "20K" setting
I bloody hate Electrics,
Cant see them,
Cant smell them,
Cant hear them,
Then the bastards bite you !!!!
