Gentlemen, Ladies
As of 1 January 2012 I have decided to get out of the Grounding Harness business. Yamaha has a current recall for this problem that will protect that nasty S4 spider, although the S6 and S7, which have also given us grief, remains unprotected. If your bike is a victim of the dreaded spider bite, take it directly to your Yamaha dealer and take advantage of the recall - it will cost you nothing.
If after you have the recall performed to your bike and you desire to go beyond Yamaha's solution, there is someone who can help you out. FJRForum member Art Cooper "road runner" has an excellent series of harnesses that will essentially do the same thing that my Grounding Harness did. His fix is to add a line from the various pigtail connectors of the high amp devices to an engine bolt. The net effect is to bleed off some of the current traveling across these "spider" connections and redirect it to the frame which is bonded to the battery with the ground strap. I have no problem recommending his solution going forward, he does excellent work. Check it out...
Ground Spider overload harnesses takes the high load away from spiders
I'm sure Art will be happy to take care of your needs.
As for my friends who purchased my Grounding Harness throughout the past 2 years, thank you very much, Please do me a favor and support your favorite tire manufactures and get out and ride.

Here it is...
My answer to the melting grounding shunt issue that has been plaguing the owners of Yamaha's second generation FJR 1300…
In contrast, here is Yamaha's Recall ground harness...
Please notice the Recall ground harness only provides an alternate electrical path for 1 pin in 1 spider to a large connector further up stream. . My Grounding Harness connects up to all 36 pins and provides a direct path to battery negative terminal.
For those of you who don't have the time to read the dozens of pages on this subject , here is the condensed version of the issue…
Yamaha upped the alternator output on the 2nd gen. bikes in 2006. They also introduced a new method of tying all the black (return) wires together on the way back to the battery negative terminal. They used a 6 pin Sumitomo MT connector that is open to the environment. When the bike is new all the connections are fresh and have minimal resistance to the current flowing through them.
In order to keep cost down they engineered the smallest gage wires to do the job. The largest wire that the connector is rated at is 1.0 mm2 (16 gage). My opinion is that the wire is large enough to work, but the connectors are the weak link. As the bike ages the pins oxidize thereby adding more resistance to the current. When this resistance builds it causes heat. With heat brings more resistance, and so on. Left unchecked, this is a recipe for a classic thermal runaway condition (see picture below). If all they had to do was handle 1 or 2 components, there would be no issue. However, these spyders are connected in series; the ones closest to the battery channels all the current on 1 skinny pin. It's typically that one, and the next one upstream from it on the fairing sub-harness that have a history of failure. My Grounding Harness takes the place of the forked shorting bars (aka ground spyders). It provides a second path of 10 gauge (thick) copper wire back to battery negative terminal for all 6 grounding shunts on the bike's wiring harness. Thats 6 groups of 6 wires attached to the 10 gage wire. The whole idea is to keep this from happening...
Several weeks back I built my first "proof of concept" Grounding Harness on my '06 AE model FJR. Prototype Grounding Harness Since then I built and installed 3 more, one on Don Carver's '06A, one on Roy Epperson's '07A, and one on my buddy Brian's 08A. All went in smoothly and have no reports of ground loop issues. The radio reception on my bike has not been impacted. What's involved is removal of the fuel tank, T bar, and heat shield. Removal of all 4 dash panels. Removal of the left side cover (by your ankle), and removal of the left inner fairing panel (behind the turn signal, next to the radiator/horn). Then you locate and remove the 6 grounding spyders (the ones with the all black wires) and attach my harness to them. My harness also attaches to the battery negative terminal. The other 2 spyders are serviced with dielectric grease (provided) reassembeled and tucked out of harm's way. It's not a difficult job if you are handy with some basic tools. The job will take about 2 hours if you keep at it. The 2 "Spider Nests" above the headlight sockets are the trickiest to get to. I am providing instructions on my personal website on how to install it. I am tooled up and am in production now. As of today I have 18 Grounding Harnesses ready to ship. My price is $90.00 plus shipping - UPS Ground, unless otherwise specified. This following is the waiting list gleaned from my Prototype Grounding Harness thread. I will send PM's to each in order as Grounding Harnesses become available. This PM will direct you to my personal website where you will make the PayPal transaction. VERY IMPORTANT... Please include your FJRForum name in the comment area on the PayPal order page. I need to keep this list up to date.

If you made a request on another thread and your name isn't listed above, send me a PM and I will get it up there. If you wish to buy a harness and haven't yet asked, please post your request on this thread. If I have you marked Deferred until later, when you are ready just send me a PM indicating so and I will re-activate your name at it's original place in line on the waiting list. For those of you with a 3 digit IBA number (the flea on the back of a flea, on the back of a flea), Let me know up front and I will attempt to accommodate your schedule. Many thanks to RZ350 and RoadRunner for the excellent work they did on tracing out the grounding circuit on the bike's wire harness. My Grounding Harness isn't the only fix offered on this FJRForum, RoadRunner went a different direction with his harness. Which ever method you choose, you will have addressed a major fault that has reared it's ugly head. Take care of it before your bike has a melt down and leaves you stranded several thousand/hundred miles from home. Thank you.
