DEcosse,

Got bike back in parts. They had destroyed the original ECM, they tried to take the back off for some reason. Anyway I got another one but havent tried anything yet because they had lost some of the bolts holding tank and airbox and other things on and they had to order some more. Gonna pick them up tomorrow. Hopefully I can get back together and look at some things this weekend or next week.

Unbelievable!!!
You should make THEM pay for the replacement.

PM me to draw my attention back to this thread, when you have all the pieces and are ready to work on it
- I don't always look in on the Tigers on daily basis

DEcosse,

Finally got some time to do the checks you suggested. Here are results;

I checked #6 fuse along with all the rest and got 11.9v on all fuses on both sides.
I have all lights will come on when key is turned, engine light and neutral light and oil light , horn and headlights work too.
Fuel pump comes on and cycles off when pressure builds up.
Engine will not turn over when trying to start. Nothing!!
With key on, I get a .2v reading on ECU case. Dont know what thats all about. Triumph tech said that shouldnt be.

Just for kicks , I hooked up the old ECU that they tried to take the back off , just to see what it would do. Now nothing comes on. So it is really no good now.

What you think I need to do now? Thanks!!

Can you clarify "will not turn over":
Do you mean it won't crank or that it is cranking but won't fire?

As for the original ECM - no surprise there - still shaking my head over that one

Positive news that pump is priming with ignition on.

Do you know the history of the replacement ECM? Especially need to know the source model - best to use TuneECU to check what map is loaded and probably even upload the correct map

Ignore that ECM voltage thing - another piece of nonsense from an unqualified source

The motor "not turning over" is it is not cranking. Like kill switch on or sumthin. Oh and the rpm jumps up to about 3500 when you try and crank it,although nothing is turning over. I might try the TUNE ECU this weekend. I havent had much luck with it as far as getting that up and running and getting any readings on anything. I'll let you know what I find out. Thanks!!

OK - that is nothing to do with the ECM then.

For the starter to spin, you need positive power and ground return simultaneously to the starter solenoid - these are both switched sources so could be either that is missing preventing the solenoid from operating.

Ground - this comes via the clutch interlock switch - probably been a while, you are remembering to pull clutch lever, yes?
Otherwise need to make sure the switch is actually closing.

Positive - that comes via the Kill switch and on to the Starter Switch: we know that the Kill circuit is good since you have ignition power (confirmed by idiot lights and the pump priming); This signal also interrupts the headlight power so is good indicator for whether your start switch is operating - press and hold the start button WITHOUT operating clutch lever - do headlights go out while you hold start button?
If yes, then positive circuit is good - look to the clutch switch interlock as source of problem
If no, then start switch is not closing properly - look to the start switch itself.

Also, just check on the solenoid itself - make sure that the low current control wires did not get knocked off in the process of messing with the ECM

This (and the preceding) thread have been a fascinating contrast between a logical methodical approach and its opposite (including believing dealers). Should be pinned as an educational item!
