stator-wire-repair14s.jpg (92449 bytes) stator-wire-repair13s.jpg (85764 bytes)   These are the yellow Stator wires I'm soldering up here.  I tin each wire with solder first, put a large crimp connector over them with the wires overlapping each other and crimp them.  Then I add more solder to the crimp connection.  I don't know how to make a better connection, but then again I haven't burnt up a stator ever that I can recall since I've been soldering my connections like this.  

Notice that I have colored tie-wraps of different colors on each wire set.  When I cut the plug out I matched up the wires with corresponding color wire ties to make sure I connect the right wires back together just as they were in the plug originally.  I don't even know if that matters on the stator or not as they're all yellow wires and it may not matter which one goes to which, but just to be on the safe side...  Also, I pretty much always use 2 pieces of heat shrink over any soldered connection instead of one.  It's a little safer I think and not overkill when it absolutely has to be fixed and the repair needs last a long time.

stator-wire-repair18s.jpg (75222 bytes) stator-wire-repair19s.jpg (69205 bytes)   I tape around one connector, then another, then all 3.

stator-wire-repair20s.jpg (107482 bytes)   Then I tape the whole thing.  I checked all the plugs that go around the battery area and found most to be lacking.  I ended up cutting all the plugs out and soldering all the wires that connect the fuse box, turn signal unit, reserve lighting unit, main switch, starter relay, voltage regulator and stator.  I only went looking to do the stator and regulator!  The harness looked just fine on the front end and at the rear.  I just think someone was spraying water around in that area and it got down in some of those connectors and left like that.  Big job, but I shouldn't have any worries out on the road and that's what it's all about.   david@kz1300.com


NOTE: On these newer browsers I've noticed that they don't always display my large images in full size when you open an image from the thumbnails.  Once you click the thumbnail and open the larger image, if you 'mouse over' the image you should see a " + " symbol or some other indicator like a box with arrows usually on the bottom right edge of the image.  If you click on the indicator, then the image will expand to it's full size which displays full screen on computers that use a 800 x 600 resolution setting for the monitor.  If you click the indicator again it will go back to the smaller image. Some people use a resolution setting of 1024 x 768 or higher on their monitors and for those users the images will appear smaller than full screen in size.  You can change your monitor settings easily enough if you desire.  Also, the indicator I've noticed is slow to appear even after the image appears to of completely loaded.  The indicator in Netscape seems to be a lot faster to display than the one in Internet Explorer.
