Advanced troubleshooting (ECU failure?)

That one little connection looks sketchy but if you can live w/it . 

You mean the second one from top left? It's the one I had my doubts about.. But the print burnt off so I have no idea what It's supposed to be.

[gstallons]

Yep ! I though I remembered techs using vinegar to remove damage from D-cell battery leakage but I can't remember. 

 Back in the mid 90s-2002 Ford p-ups would leak water through the windshield and drop onto the GEM / fuse box and cause ALL kinds of problems . You would tear into them and they would look 1000Xs worse than this . 

 This is of course damage from water intrusion . Try to reseal as good as possible when going back together.

Without wanting to discount intrusion, I reckon it is plausible that it might (also) be condensation. The air inside the box becomes humid it warms up from the warmth of the componentry. When it is all turned of, the casing starts to cool down, causing conensation inside the box. I'm not sure how likely it is in this case, but as I said, plausible, I reckon.

The described phenomenum is a big issue with sound systems at open-air events. The solution is generally to leave everything on all the way through. I heard a story from some colleagues that they had switched off the mixing desk at the end of the evening (a Midas XL3, a large analogue console...) and the next morning there was "a litre" of water inside.

When I bought it 8 years ago, the bike looked like it had been under water. So I'm not surprised to say the least. What is surprising, is that the corrosion forms an edge exactly on a quarter if the print. As if it was physically dipped in water. 

I started her up yesterday evening and she runs like a sewing machine again. Very happy!

IDK if anyone  where you live that repairs PC boards that can offer a spray to put on the board to stop / prevent any future problem(s) ?

 I am glad you got it started .

It does exist.

Personally I'd be buying a spare ecu JIC. The other issue these 15M ECU's have is the Baro pressure sensor failing. Not a big deal if you live at seal level and don't ride into the mountains. You'll know it's failed via Guzzidiag if it shows dashes in the baro readout screen or if the bike starts acting a bit flaky with significant altitude changes .

That brings up the question if @Mechanism's V11 now connects to guzzidiag (?)

I also got a kick out the phrase "seal level." After all, when was the last time you saw a seal in the mountains?

If you search for "conformal coating" you will see many products that offer a protective, breathable coating of thin polymeric film that does exactly what you want. Then you can immerse the bike again and it will still start. 😄

Mountains = good!

Seal Level =  okay . . .

Below seal level = NO GOOD!

Listen , I helped him get it running . AFA I am concerned , I would get a GOOD ECU , have a good map installed  and  run it. I am sure no one would risk running this ecu and having it fail on the road . My days of pushing (British) motorcycles back to the house are long gone .  You want to ride them uphill so WHEN they quit , you can ride your zero emission vehicle back home .

 There was this rich farmer that had an ultra-lite and he would fly by here a few times a week . this thing sputtered 10Xs worse than anything anyone on this forum has ever witnessed. The Lord God Jehovah , Yahweh , The Great I Am  etc. kept this man alive to make it home every time.  I would like to think He will help me but might say " Don't look at me I didn't tell you it would work" .

Still have to try if Guzzidiag connects. But very confident it will work again.

Also noticed the time between turning on ignition and priming of the fuelpump has been reduced. It's instant now, but used to take 1 or 2 seconds before.

Exactly. But this buys me the time to get a really nice one, and have it flashed and "plug and play ready" in the future. 

Many thanks for your support!

To think that most of my country actually IS below sea level 😉
