Clusters from same age/model should work, those from different age/model likely won't.

For me the clue is in the delayed rev-counter sweep issue. On the video, it showed an immediate sweep on switch-on, as it should. But then a second one a few seconds later! That should not happen. The only thing that could cause that, to my mind, is either an intermittent break in the ignition circuit somewhere, or a voltage on the cluster motherboard that is on the margins.

The problem is, as i see it, there's no easy way to test the actual voltage on the motherboard unless you have a complete test setup with cluster and ecu connected off the bike. You cannot get to the connector pins to test voltages when everything is connected. I had a similar problem years ago on my first T1050, and there is a cluster pins diagrammatic somewhere in the stickies.

In the end I found in my case (by hours of testing and the wiring diagram in hand)  that the fixed +12V feed was not there - and the reason was that a fuse in the fusebox that looked OK actually was not. Only testing with a meter showed that it was blown, even though it looked OK.

But you have a worse problem, an intermittent connection somewhere, the hardest of all faults to trace. Seems to me that it has to be down to the power feeds (either the fixed live or the switched live, or the earth connection) causing the problem. Repeated sweeps suggest an intermittent power feed break - whereas the earlier long delay suggests that the voltage is building up slowly enough to start a sweep.

It all points to a connection somewhere that is corroded, could be internal and invisible even, and supplying power intermittently. I know you've tested those microswitches, but have you thought of simply resoldering them on the board (in which case you could replace them anyway).

And of course what caused the corrosion. Has the bike gone from a damp to a very dry environment? Or vice versa? Humidity in garages has been known to cause problems in the UK.

Hi All, Thanks again for all your responses, guidance, and suggestions. From a number of additional conversations/texts/emails with Triumph owners and mechanics, my next step is to replace the wiring harness.

A Tiger 1050 comrade in New Hampshire with the same intermittent sweep/delayed start issue has been doing some parallel research and rec'd feedback from a Triumph Master Mechanic who has seen "similar electrical buggy" issues with multiple Tiger 1050's. Replacing the wiring harness resolved the issue on those bikes.

I'll report back!  :028:

If your sure it's the harness.



You might VERY, VERY CAREFULLY  cut the black wire tape and inspect the from right after the headstock back 8 inches.
Check each wires insulation  all asides.
I fixed that issue on several speed triples.  It's on known problem with that bike could happen on ours.

I seem to remember that a few years ago there was a recall on Sprint 1050s to replace the wiring loom because of breaks just behind the steering stem.

    :0461:   Stem/.. Another good way of saying it..

Reason I said in front of of head stock was to give a little  space to  inspect from the stem back.   The one I fixed was within 2 inch behind the stem. 
Had to cut more tape to allow a splice, solder and heat shrink the 3 wires I found affected or effected.  Always have a hard time getting the right ffected.

If you do replace the harness, looks like there are 5 different part numbers for the '07-'12 depending on if it is an ABS or non ABS model and broken down further by the VIN#.

T2500890 - Non ABS up to VIN# 461331
T2501061 - Non ABS VIN# 46132 to 46839
T2500891 - Non ABS VIN# 468640 and up
T2507000 - ABS version up to VIN# 440482
T2507001 - ABS version VIN#440483 and up

Looks like they are still available new but at $570US, eBay might be a cheaper option. But it is always a gamble buying a used harness. It is a lot of work to replace only to find the used one has issues too. :157:

I replaced the wiring harness/wiring loom with a used one from eBay (fit perfectly). I'm still experiencing the same start/sweep delay, no improvement  :087: :005:

Now that the original loom is on my garage floor, I'm I'm going to carefully inspect it, particularly near the steering stem.Thanks again for all the suggestions and guidance!

Maybe you need to find a really good friend and start swapping components off a healthy bike. At least you can exclude the entire wiring harness (but not the interface connections to the rest of the bike). Sounds like a nightmare, sorry.

Getting a bit drastic & expensive.
