possibly found the culprit

[phil_long]

ok, so i been chasing this voltage issue(low voltage on my SM), and been researching a lot between Steve's website and turbobuicks.co m.  I decided to look at the ecm after looking at the ign switch, bat terminal, etc.  Seems like i'm getting about 4 tenths of voltage diff when just moving the ECM.  I want to check the connectors for corrosion, but my dumb behind dont know how to remove the plug without breaking anything.  and, which wire into the ECM am i checking for? pink/black?  thanks

Phil...if you look at it, you will see some retaining clips that hold the connectors down...pop them loose

Then pry gently up on the connectors, one at a time, and they will come unplugged.  Seems like one has to come off before the other one can come up/off.

Believe A6 is the one that you want   http://www.vortexbuicks-etc.com/ecmwiring.htm

I would unplug the the battery just in case you touch the wrong spot while cleaning....ev en tho A6 comes from the key.

Beyond corrosion, look for any pins/wires that are not completely pushed into the connectors....

will do.  Thanks steve

This is really pissin me off.  im trying to upload some pics so you can see my findings and ths stupid thingy keep spinning in circles

[Steve Wood]

just fix it...ten thousand words are a lot more interesting than a picture!

would alcohol be safe to use for the pins?

[phil_long]

ten thousand words?? Lol

[Steve Wood]

looks like you have had the classic water leak....best solution would be to buy the new harness ends from John Spina and start soldering.

Alcohol should not hurt, don't know if it will help

I have not had much luck with contact cleaner...migh t be tempted to try vinegar right before I called John to order the new connectors...

Ed probably knows how to clean them...I guess a soft brass brush might help a bit?

[Steve Wood]

Fix that and your car will go down the road saying thank you, Phil, I love you, Phil....

[phil_long]

are the ends from John expensive? Soldering is right up my alley, but doing it in that little space could suck.  Is there a link to that part from john?

[Steve Wood]

I am pretty sure he has them, but, I can never find anything on his site unless I am having an extra lucky day.  Davewentmissis ing will find them I would guess

[phil_long]

thanks steve.  im going to try and clean the contacts as best i can for now

[daveismissing]

These are nice- maybe your mechanics/comms guys have one to borrow?
