ok... here are the findings from the tests...

3 wire connector:

B/blue & Brown = .340
B/blue & g/w = .345
All is good there

B/blue = .001
Brown = .001
g/w = .001
All seems well here

Between Black/blue & Brown = 1 (i think this is infinity??? I dunno... )
Between Black/blue & Green/White = 1 ( I think this is infinity... )

1.  Did i do the test correctly? 
2.  What do the findings translate to?
3.  I hate electrical things!!!

I'm not sure what any of this means.... i set the multimeter to 2K (thats what is said) on the section with the omega not the "V".  I plugged the red probe into the far left plug (had an omega) and the black probe into the middle plug (labeled COM). 

Rats!  So much for the checklist.... 

Actually, your first test (values of .340 and .345) told you everything you needed to know.  Those readings mean that everything is well-connected from that first 3-wire connector all the way down to the signal generators and back.  Only if one of those had come out '1' (infinity, as you thought) would you need to continue down the list of tests.  Time to "refine" that post a bit....

The only related test that I can think of is to make sure that the connections to the OTHER half of the 3-wire connector (and THROUGH the connector) are good.  Otherwise, it's back to the drawing board.

Sorry if I got your hopes up.  I guess I'm out of the running for "Smartest GS'er".  Sigh.

its cool man... thanx for all your help...

What do you think about bad rings???  I dunno

Auxillary ground ... you knew it was comming.
Cool.
Srinath.

yeah... i know... i redid it twice!  I'm not sure where, however it bolts to the frame... where

Battery to wiring loom ... and then ... no idea ...
Also that same thing happened on my virago 535 and was a black box error.
Cool.
Srinath.

KY, did you try the suggestion posted earlier about taking off the exhaust and holding a piece of paper over the ports while cranking it over?  I wonder if there isn't a carb problem at the bottom of this considering how much of the electical system you're already replaced.

-M

ya got to isolate it....
old fire triangle stuff
air/fuel/spark
and in an engine....compression
what are you missing

untill you determine what ain't working you will not be able to fix it
really....is it a fuel prob or spark prob

did you paint the frame?
is the coil properly grounded to the frame....
did you swap coils and get the prob on the right?

 
In case it will help, here is a shot that I took a long time ago, with newly-added annotations:



The camera was held between the exhaust pipe and the front edge of the rear tire, pointing toward the front of the bike.

Here's one I don't think has been mentioned.

Bad diaphragm in the fuel pitcock resulting in sucking fuel thru the vacuum line and putting out the light in the left cylinder.

................................................
The only ones i haven't replaced are as follows:

Kickstand switch wire (possible???)
Oil pressure wire (possible???)
Rectifier/regulator (possible???)
clutch switch wire (posible???)

I'm going to look at that diagram (which thanks to kerry has been on my computer for some time now) and see if these could relate... I'm not sure.... lemme know what you think

These are not related to the ignition circuit in a way that would affect only the left cylinder.

[=s

ok... lemme try to remember all the suggestions...

Carbs:  I've got the best way to test them... since I just got ANOTHER GS that runs great... i'm going to swap the carbs tommorrow (its my day off).  If its carbs then the bike should run great now!

Auxilary Ground - ok... kerry... i thought i checked the auxilary ground... as  a matter of fact I thought I checked it twice.  I knew this was the first and most likely cause (and srinath as well) but that pic doesn't seem familiar to me.  I'll check that as well.

Coils being grounded to the frame:  I need to approach this at two different angles.  This problem has always existed even then my coils were tightened against the frame (and the bike hasn't been painted (the frame that is).  But now they are loose cause I've been taking them on and off so i left it that way for easy access.  I'll put them back on tight now though.

Compression:  I checked and that area is fine.  I'm starting to think fuel or aux ground must be this issue.  I'll also try the exhuast removal if none of the above work!

You guys have been so much help... hopefully we'll crack this one soon!  I'll get my findings back soon!

Thanx so much,
Austin

ok guys... i'm looking at kerry's picture... I'm not finding this auxilary ground wire.... is it the one that connects to the bottom of the oil pan??? if not could some one describe with words what it bolts into???

Back side of the motor if I remember. And John Bates suggestion is also a good possibility. BTW so is carb synch and the air screw setting ... if one if hooked or rammed too deep ...
Cool.
Srinath.

Just to confirm ... on pre-'01 bikes, the vacuum hose connects to the left carb.  On '01+ bikes it connects to the right carb.

Oil pan?  Yeah, I guess that's what it is.  If you're standing on the right-hand side of the bike, the ground wire connection is BEHIND the bundle of drainage tubes (and signal generator wire) that peek out between the frame and the rear of the engine ... just forward of the rear brake lever.

It's not the easiest thing to do, but you should be able to positively identify the ground wire by starting at the '-' terminal on the battery and following the wire down around the left side of the bike, kinda under the airbox, and across the back of the engine to that "bundle".

PS - I don't know of any reason that the ground wire HAS to be connected where it is.  If you have replaced the wiring harness you may have bolted it on somewhere else.  As long as it's a good connection....

i bought one once that had same problem turned out to be a broken wire from the ignition pick-up coil inside the casing about 8 inches back from ignition coils .look there .

+1 I lost a cylinder when I pinched one of these. I stillhad spark sometimes though.

Hey... i tested the resistance set at 2k on the ground wire (placing on probe on either end of the wire) and I got .000.  this would tell me that its a good wire... and the connection is good cause i double checked it and  put it back on... this is the phantom of all problem!

I hate this...     my bike
