So the Uly completly died on me about 350 miles from home. Leading up to the death, the instrument cluster lights started flickering. The engine was stuttering, occasionally the needles would reset and the check engine light would come on. As this was happening I was trying to recall this site and all of the numerous threads I've seen with similar symptons. So when the death finally happened on some back road in VT, I popped the seat off and checked the ecm. There was a hairline crack in one of the connectors and with some wiggling I was able to get the bike back on. Further wiggling would dim the instrument cluster. I grabbed a zip tie and tried to secure it as best I could. I was able to make the 50 mile trip to the hotel without issue. We'll see what today has in store. So when I get back home will I just need a new ecm? Is there any fixing this? | ||

The first thing to do is to move the ECM or make something to keep the seat off of it. The seat flexing downward and putting pressure on the connectors is what cracks them. You can find lots of threads here about moving it. I believe a couple of people here have successfully carved the potting material out of the bottom of the ECM and re-flowed the solder on the leads from the connectors into the printed circuit board and then poured fresh potting material into the ECM case. If you've got some electronics skills, that shouldn't be too bad of a job. Alternatively you could buy a used ECM pretty cheap. | ||

It doesn't look that bad to go do surgery on the ECM. Once you have access to the solder pads, resoldering them with some certified "not lead free so it will actually work" solder from your secret stash contraband solder should be almost trivially easy. They are nice big solder pads. |
