Replacing pin on ECU?

[SVboy]

I have a manual on CD. Will check that out. Bike is std-had tail tidy.

I have a manual on CD.

Armed with the wiring diagram, I would print a copy, grab a highlighter to mark circuits you have checked, and starting from the battery go thru the circuits from the battery forward, doing nothing more at this stage than a visual inspection for obvious problems, and with the bike running moving each loom and connector around to see if you can get the fault to trip.

As you go through each connector, unplug it and look for bent/displaced pins, corrosion, melted plastic bits or any other problems. A squirt of CRC contact cleaner wouldn't go astray while you are there but that's more a preventative measure.

Thank you ALLUN, and IMDYING-you have given me good advice on where to start. Will keep you posted.

Um isnt the red light the oil pressure light? If it is then its not really helpful other than to say the engine has stopped pumping oil, it would possibly be showing how fast power was restored to the circuit but its not a good indicator of any cause as it would hold up for a second or so until pressure drops.

.......o FI code on the dash, but the ignition light comes on.......

.........Thinking more-the red ignition light would......

It's the FI/IGN light by his descriptions....I think it has a key symbol on it?

What pin # is it?

[SVboy]

I stripped out the key barrel and ignition contacts over the weekend. Lots of muck in there, which I have cleaned up. Will report back when I get a chance to test it out.

Tip over switch!!!! Dirty or loose contacts maybe

I will check the TOS-it is seated correctly, but the penulum my have had a hissy-will remore cover and check....

i second that ive heard of ppl siliconing them in position so they dont turn when ya tip over

[SVboy]

It is with great relief that I can report that the fault was caused by the kickstand moving a bit, and causing the cut out switch to activate! All sorted!! Yay!

I think this is going to turn out to be nothing to do with the ECU pin, sounds like intermittent connection that is going bad when things move around due to the cornering force, the lean angle, the vibes at certain revs, or similar. Could be a wire or crimp going bad, or a dodgy switch on sidestand or anywhere else that kills the ignition.

Dodgy sidestand switch in the end huh?
Don't even ask about the blood sweat and tears that burned that particular lesson into me!

Glad you got it sorted mate :-)

[SVboy]

Cheers, I appreciate yours and all the others advice offered[even DBs!] in sorting this headache!!

You should be able to tell if the pin is unused as there will be no wire coming out of the plug in that position.

When the mechanic discovered the corrosion on the ecu pins/plug I got then professionally cleaned and neutralized, then we carefully checked the pins against the workshop wiring diagram, identified the missing pin no, and were happy to find it was a spare, and its absence has no effect. Thank god!!
