i thought i should share some thing i learned today.

yesterday i had to take the tank off, and battery, to top up the coolant. ( minor spew of blue water while ticking over in traffic)

i put it all together and she ran fine. unfortunately the yellow engine management light was on. bike fine but annoying yellow light. i read the posts "money light on etc" and resolved to try the suggestion of letting it heat up from cold to hot ( fan running ) 3 times, in the hope of clearing the false fault.

i telephoned the dealer in cheltenham today to see what they thought. he kindly said visit us and we will connect it up and clear the fault, "we often get that when battery and fuel sender has been disconnectd". i asked are there any DIY tricks to clear the fault as i could not go there untill weekend and the tip is:

when hot stop the motor on the kill switch and leave it off for 20 seconds. and guess what it works! system reset and light gone away and me and tiger happy again!

Are you sure it wasn't the 3rd heat cycle when you did this?

it was the second time; sunday i discovered the warning light after reassembly (cold), and it was still there after a ride. monday night i warmed it up and used the kill switch so it was second heat cycle.

i dont know why though, its all magic to me.

have you had the same? did the 3 cycle trick work for you?

why dont triumph explain this in their owners manual?

I've been through the 3 cycle thing many times. I've got the factory shop manual and it describes the process. I have since gotten a tune boy so I can check what faults trigger the light in the 1st place, but low battery is pretty common. I've gotten some from turning the ignition on with one or another sensor unplugged. I've started the bike without hooking up the fuel level sensor and that also triggers a check engine light.

fantastic! thank you ! now i understand what happened( or what i did wrong )

on sunday after topping up the coolant i started the engine briefly, with the petrol tank off, to circulate the coolant to ensure cylinder head full. i supported the tank at the side of the bike and connected the fuel pipe and the fuel pump, but not the fuel level sensor. then topped up the coolant a little again, then reasembled the whole tank, battery saddle etc. ( it is a pain not having easy access to the thermostat/filler point)
when it was all done and i went for a test ride the yellow light was on.
The light cleared after 2 cold to hot cycles but there were probably 3 or 4 starts.
so lesson 1 is dont start the bike without a sensor connected.
lesson 2 is dont panic if you see a yellow light, just browse this forum for advice!

thank you again, steve

When I serviced my bike I was forced to turn the ignition on and off a few times with sensors disconnected, as part of the annoying process to put the alarm into service mode. As expected the yellow lamp came on after I'd put the bike back together but I found the three warmup/cooldown cycles cured it for me...

But what interests me is that I had some dodgy electrics connected to the accessory socket whilst I was camping in Scotland a few months later; I woke up to a completely flat battery (about 4 volts!). After an entire morning of attempting to jump start the bike off ropey jump start batteries and the alarm going off constantly (I could really grow to hate Datatool) I acquired a brand new battery, installed it, and the bike fired up instantly with no ECU warning light at all! How I got away with that one, I'll never know. An entire morning turning the ignition on and off and running the starter motor with the voltage varying between about 2v and 12v and no fault codes were logged! :hammer:

3 cycles always works for me.
