Thank you Don. for chiming in here.


I removed the donor parts and reinstalled the OEM parts.


After I reconnected the Kill switch cluster everything was now functioning again.


But after some thought, I was moving the fuse box around to see if I could see the elusive two grounds under the faux tank.
So what Did I do to get it back online?


I had charged the battery (Bike been sitting a few weeks.)
Got to have a fully functioning battery for testing.


So I let the bike run for about 15-20 minutes (It never died this run) I Might add the longest it has since I bought it DOA.


All the gauges were normal. Charging at 14.1-14.3


Now being the investigator I am.


I needed to know what go it up and running.


The bike has a open hose. (Nosier than normal.)
My stethoscope says its under the air box plenum.


So I pulled the faux tank. to see if the Air box was sealed tight?


It has new filter in it.


I Think I found the suspect (Connection)
Smallest plug of the three out of the fuse box.




I'm soaking both ends overnight to dissolve the corrosion. (I'll pack all three with dielectric grease to keep moisture out of them)




Looking at the Plenum from my parts bike. I can see where the Vac leak is on the new SEi.
The Plenum has to come out. (wish I knew how to post pic's here)



I want to detail the engine anyways, So no worries there.






Now for Don's questions.


When the bike did start. It would idle at 1100.
Then drop to the mid 800 RPM range after it warmed up.


The eng did stumble when I rolled on the throttle.
My though at that time was.
It needs a good dose of Techron/Seafoam to get the injectors cleaned. (Sat for at least 3 yrs before I rescued it)



I been concentrating on parts restoration the past few weeks.
Until I tried to run the bike one last time before,
I removed all the parts for the transformation.


Kind of Glad I tried to run it and found the problem now instead of after I put it all back together to find out "why" the PO gave up on it!!.


I love these older bikes-my 87A was bullet proof, as was the LTD.
I like these injected bikes the most.





After I got it back online today.

The stumble if gone.



I tried shutting the bike down at least a dozen times to watch the dash.


The cray kill switch things I seen this morning are history.(poor connection issue)



I don't know how to upload a pic here? (of the dash with all the lights lit up.)



I've owned a LTD and the SEI I just stripped was a running bike. So I know what a good running LTD/SEi dash looks like.




So I'm hoping the fuse box connection was my Huckleberry?.


All the OEM parts are back on and the Computer shows 5 red lights. then then go out after a few seconds.




You thoughts Don, on what I found?? (Thank You Sir!)
