My post was more of an FYI than anything else since the modules are a mystery to many.

Wow, that's a really easy test.  Will be good info for people in the future if they don't have access to a running bike on which to test there modules.   That is if the test is reliable.

I did the test on three other modules I have (the other original to my bike and a spare set) and the results are pretty much indentical. What the test doesn't do is give readings while there is a load on the circuits. So, they could pass a simple bench test and still not work once in use. Oh the joys of solid state electronics!

Nice work!  Yep, the best test is substitution. 

She's alive.   

After a lot of  over the modules, I decided to get creative.  So I got my hands on Rameses' stock 1100 DS ECU and installed that.  It was a difficult procedure, but after some ingenious engineering, it fired right up.

Actually, I think it has more power than before as it seemed to wheelie a lot easier.

so....

what did you really do?

What do you mean   I took some pics because I figured no one would believe this. 

As you can see, the ECU is powered with an external power source as not to take away power from the engine.  The blow off valve is also visible in this shot:



From the other side, the oil filter is more visible.  It is used to filter out the dirty horsepower and, as you can tell, makes this bike a green machine:



And this over head shot shows it all.  The gauge is very important in order to monitor all the power and make sure I'm not about to blow up.  And the combination wrench provides critical contacts and grounds between the ECU and the air/power barrier.



Then it was time for a little test ride 

Not fair! 

Okay, the actual solution was fixing the connections in one of the plugs on the modules.

After pulling the three wire terminals out, and bending out the contacts inside the terminals to assure that they were making contact, it fires up and runs fine.   


I'm sure Jobu can add more detail as to which plug it was, etc., when he gets done at work.

So he stopped effing around and fixed the damn thing....

No, the effing around took place after it was fixed.

  Sorry Howie.  I'm a dickhead.

As Rameses said, there was a bad connection.  It was on the module that runs the horizontal cylinder at the three prong plug that goes to the coil.

However, that doesn't explain why the other cylinder wouldn't fire.

Here's the entire solution:

Howie, I took your suggestion and started checking for ground and power at the respective wires.  Everything was checking out fine but still no spark.  There is a two prong plug, not the pickup coil plug, the main plug (I don't remember exactly what it does but I'm sure Howie and Ducpainter know the one) that supplies power to the ignition.  I had checked and unplugged this plug numerous times and it seemed fine.  But decided to check it better.  I cut the black insulation off to get to the main wires (I think there two red and two black).  While checking voltage on one of the red wires, I decided to fire the starter to see if that was causing anything fishy.  And low and behold, the damn thing fired up, albeit on one cylinder, but I was so happy to here that desmo tune that I got a chubby.      I guess there was bad connection there as well.

So, then I started tracing wires from there and eventually got the other cylinder to fire intermittently.  With Rameses' help, I was able to find the bad connection as he described and got it running good.

It is officially now running the best it ever has and finally wheelies like a 2V 900 is suppose to.  So of course I had to clown around a little. 

Thanks for the help guys.  I make the beast with two backsing hate electrical problems.  I'm just glad that it cost me absolutely nothing, except for a little gas money, to fix. 

Gotta say, those photos and the accompaning text are hysterical.   Congrats on fixing your bike
